Suggested April 2024 How To Record Terminal Session In Ubuntu

If you are a frequent terminal user, you may come across situations where you need to debug the code or copy the output of a script for future reference. For such cases, you may want to record the terminal session to obtain the log file of all the input commands you have entered and their outputs. Here is one way that you can use to record terminal session in Ubuntu.

Setting Up

Open a terminal and install bsdutils

sudo

apt-get install

bsdutils

Once installed, you will be able to use two commands script and scriptreplay to record the existing session and play back the recording.

Usage

The usage is pretty simple. To start the recording, you just need to use the command:

Once you entered the command, you should see the line “Script started...“. Everything that you enter in the Terminal (including its output) will now be recorded.

Once you are done with the recording, simply type exit to end the recording. You should see the line “Script done,...” that denotes the end of recording.

To view the recording, you can either open the saved file (recording.txt) in your text editor or use the command scriptreplay

scriptreplay ~

/

timing.txt ~

/

recording.txt

That’s it. While it is simple, it can be really useful for debugging, or even troubleshooting your friend’s computer by showing them what you have typed and the expected output they should see in the terminal.

Is this helpful to you? What other uses can you think of?

How To Add Or Remove Ppa In Ubuntu Using Gui And Terminal

Ubuntu is one of the most popular Linux-based operating systems used by millions of people around the world. It is known for its ease of use, reliability, and security features. One of the most important features of Ubuntu is its package management system, which allows users to easily install, update, and remove software packages on their system.

One of the most popular ways to install software on Ubuntu is through Personal Package Archives (PPAs). PPAs are repositories that contain software packages that are not available in the official Ubuntu repositories. They are typically maintained by individuals or teams of developers who create and maintain their own packages.

In this article, we will discuss how to add or remove a PPA in Ubuntu using both the graphical user interface (GUI) and the command-line interface (Terminal).

Adding a PPA using GUI

The easiest way to add a PPA in Ubuntu is through the GUI. Here are the steps −

Step 1: Open the Software & Updates Tool Step 2: Go to the Other Software Tab

Once you have opened the Software & Updates tool, go to the “Other Software” tab. This tab displays all the third-party repositories that are currently enabled on your system.

Step 4: Enter the Details of the PPA

In the new window, enter the details of the PPA. This includes the PPA’s name, the PPA’s location, and the PPA’s key. You can find this information on the website of the PPA’s maintainer.

Step 6: Close the Software & Updates Tool

Once Ubuntu has finished updating your software sources, close the Software & Updates tool. You can now install software packages from the newly added PPA using the Ubuntu Software Center or the Terminal.

Adding a PPA using Terminal

If you prefer to use the command-line interface, you can also add a PPA using the Terminal. Here are the steps −

Step 1: Open the Terminal Step 2: Add the PPA

To add a PPA, enter the following command in the Terminal −

sudo add-apt-repository ppa:PPA-NAME

Replace “PPA-NAME” with the name of the PPA you want to add. For example, if you want to add the PPA for the GIMP image editor, you would enter the following command −

sudo add-apt-repository ppa:otto-kesselgulasch/gimp Step 3: Update your Software Sources

After you have added the PPA, you need to update your software sources. To do this, enter the following command in the Terminal −

sudo apt-get update

This will download and install the key for the PPA, and then update your software sources.

Removing a PPA using GUI

If you want to remove a PPA from your system, you can do so using the Software & Updates tool. Here are the steps −

Step 1: Open the Software & Updates Tool Step 2: Go to the Other Software Tab

In the Software & Updates tool, go to the “Other Software” tab. This tab displays all the third-party repositories that are currently enabled on your system.

Step 3: Select the PPA You Want to Remove Step 5: Close the Software & Updates Tool

Once Ubuntu has finished removing the PPA, close the Software & Updates tool. The PPA will no longer be available on your system.

Removing a PPA Using Terminal

If you prefer to use the Terminal, you can also remove a PPA using the command-line interface. Here are the steps −

Step 1: Open the Terminal Step 2: Remove the PPA

To remove a PPA, enter the following command in the Terminal −

sudo add-apt-repository --remove ppa:PPA-NAME

Replace “PPA-NAME” with the name of the PPA you want to remove. For example, if you want to remove the PPA for the GIMP image editor, you would enter the following command −

sudo add-apt-repository --remove ppa:otto-kesselgulasch/gimp Step 3: Update Your Software Sources

After you have removed the PPA, you need to update your software sources. To do this, enter the following command in the Terminal −

sudo apt-get update

This will remove the PPA from your system and update your software sources.

Benefits of Using PPAs in Ubuntu

PPAs can offer a number of benefits to Ubuntu users, including −

Access to the latest software − PPAs can provide access to the latest versions of software packages that are not yet available in the official Ubuntu repositories. This can be especially useful for developers who need access to bleeding-edge software for their work.

Increased software selection − PPAs can offer a wider selection of software packages than the official Ubuntu repositories, which can be useful for users who have specific software needs.

Easy installation and updates − Once you have added a PPA to your system, you can easily install and update software packages from that PPA using either the Ubuntu Software Center or the Terminal.

Tips for Using PPAs in Ubuntu

When using PPAs in Ubuntu, it’s important to follow some best practices to ensure that your system remains secure and stable −

Only add PPAs from trusted sources − Before adding a PPA to your system, make sure that it comes from a trusted source. PPAs from untrusted sources can potentially contain malicious software that can compromise your system’s security.

Be selective when adding PPAs − Adding too many PPAs to your system can potentially cause conflicts between packages and make it harder to maintain your system. Be selective when adding PPAs, and only add those that you really need.

Keep your PPAs up-to-date − Just like with the official Ubuntu repositories, it’s important to keep your PPAs up-to-date. Make sure to regularly update your software sources to ensure that you have access to the latest software packages.

Conclusion

Adding or removing a PPA in Ubuntu is a simple process that can be done using either the GUI or the Terminal. PPAs can provide access to a wide range of software packages that are not available in the official Ubuntu repositories, making them a powerful tool for Ubuntu users. However, it is important to only add PPAs from trusted sources to avoid any potential security risks. With the steps outlined in this article, you can easily manage PPAs on your Ubuntu system and ensure that you have access to the software you need.

How To Change Terminal Output Color In Linux?

Introduction

The Linux Terminal is a powerful tool that allows users to interact with the operating system through the command line. However, the terminal’s default output color can be dull and unattractive. In this article, we will discuss several ways to change the terminal output color in Linux. We’ll cover the use of different commands and tools that can be used to customize the terminal’s color scheme, as well as some examples of how to use them. This guide is intended for Linux users who want to improve their terminal experience by changing the output color.

Using the “LS” command

One of the easiest ways to change the terminal output color in Linux is by using the “ls” command. The “ls” command is used to list the contents of a directory and has several options that can be used to customize the output. Here is an example of the “ls” command −

$ ls

The output will look like this −

bin@ home/ lib32@ media/ root/ sys/ vmlinuz@ boot/ chúng tôi lib64@ mnt/ run/ tmp/ vmlinuz.old@ dev/ chúng tôi libx32@ opt/ sbin@ usr/ etc/ lib@ lost+found/ proc/ srv/ var/ Using the “LS_COLORS” environment variable

Another way to change the color of terminal output on Linux is to use the “LS_COLORS” environment variable. This variable can be used to set the color scheme for the “ls” command. The variable can be set in the “.bashrc” file, located in the user’s home directory. To set the “LS_COLORS” variable, add the following line to the “.bashrc” file −

$ export LS_COLORS='rs=0:di=01;34:ln=01;36:mh=00:pi=40;33:so=01;35:do=01;35:bd=40;33;01:cd=40;33;01:or=40;31;01:mi=00:su=37;41:sg=30;43:ca=30;41:tw=30;42:ow=34;42:st=37;44:ex=01;32:*.'

The line above sets the color scheme for different file types. For example, “of” represents the directory and “1;35” represents the color code of the directory. Similarly, “ex” represents the executable and “01;32” represents the color code of the executable.

Using the “Tput” command

The “tput” command can be used to change the color of terminal output on Linux. The “tput” command can be used to set the color scheme of the terminal, as well as change the background and text color. Below is an example of how to use the “tput” command to set the text color to red −

$ tput setaf 1

The above command sets the text color to red. To change the background color, use the “setab” option instead of “setaf”. Here is an example of how to use the “tput” command to set the background color to blue −

$ tput setab 4 Using “Gnome-Terminal” ANSI escape codes

Another method to change the color of terminal output is to use ANSI escape codes. ANSI escape codes are standardized commands used to manipulate the behavior and appearance of text in a terminal or terminal emulator. For example, we can write a script that prints the red words “Hello world” on a green background using the echo command and then resets the colors to normal −

#!/bin/sh RED_ON_GREEN='33[31;42m' RESET='33[0m' echo "${RED_ON_GREEN}Hello world${RESET}"

“33” is the most platform-independent way of encoding an ESC character in the terminal, although a reference, “e”, can also be used on Linux. Also, it’s worth noting that the color settings aren’t encapsulated in any way. As a result, if we don’t restart them, they will bleed out of our script, which is undesirable in most cases. We can find the full list of color codes on Wikipedia.

#!/bin/sh RED_FG=`tput setaf 1` GREEN_BG=`tput setab 2` RESET=`tput sgr0` echo "${RED_FG}${GREEN_BG}Hello world${RESET}" tput command

The tput command is another option that can be used to change the color of terminal output on Linux. The tput command allows users to query the terminfo database and provides a convenient way to extract the escape codes we need. For example, we can recreate the script from the previous section using the tput command −

Conclusion

In this article, we have discussed various ways to change the color of terminal output in Linux. We have covered the use of several commands and tools such as the “ls” command, the “LS_COLORS” environment variable, the “tput” command, and Gnome-Terminal to customize the terminal’s color scheme. We also discussed using ANSI escape codes and the tput command to change the color of terminal output. Using these methods, you can make your terminal more visually appealing and easier to read. Remember to use commands with the correct syntax and options to change the color of terminal output on Linux.

How To Record Your Screen In Windows 11

In the not-too-distant Windows past, a third-party app was your only option. These days, there are three separate tools built into the user experience. 

But not just have one? As it turns out, each has a specific purpose, but also its own limitations – so it’s important to choose wisely. Here’s everything you need to know about screen recording on Windows 11. 

How to record Windows 11 screen using Snipping Tool

The Snipping Tool has been part of Windows since 2002, but it was only with the release of Windows 11 that it gained screen recording capabilities. It’s very easy to capture and share footage this way, but there’s one big drawback: it doesn’t include audio.  

If that’s fine for you, here’s how to use it: 

Open the Snipping Tool app – the easiest way is by searching for it next to the Start menu 

Anyron Copeman / Foundry

Hold and drag to select the area of the screen you’d like to record 

Anyron Copeman / Foundry

Perform the action that you’d like to record, pausing at any time if you need to 

Play back the recording and make sure it’s what you were looking for 

This is an MP4 file, so it can be viewed via any app which supports that format.  

How to record Windows 11 screen using Clipchamp

Microsoft bought the Clipchamp video editing software in 2023, before adding it to Windows 11 a few months later. The app includes a powerful screen recording feature as one of the capture methods, and it supports audio too. 

However, the free version of Clipchamp limits you to 30 minutes of video at up to 1080p resolution. For anything more, you’ll have to pay for an ‘Essentials’ subscription or get Microsoft 365. If you don’t mind that, here’s how to use it: 

Open the Clipchamp app – the easiest way is by searching for it next to the Start menu 

If this is your first time using Clipchamp, sign in or create an account. You can skip most of the setup

Anyron Copeman / Foundry

From the screen that appears, select the ‘Record & create’ tab on the left side

Anyron Copeman / Foundry

Choose between just your camera, just your screen or both

Anyron Copeman / Foundry

Accept relevant permissions when prompted 

Choose your microphone and camera (if applicable), then hit the big red button to start recording

Give the app download permission, then make any edits you’d like 

How to record Windows 11 screen using Xbox Game Bar

The Xbox Game Bar was added to Windows 10 as an easy way to capture gameplay, but it can be used to record your screen and audio. However, the caveat here is that it just records the entire screen, with no way to select a specific tab or window. 

Here’s how to use it: 

Open the app/s you want to record and make sure they’re on screen 

Use the Windows Key + Alt + R shortcut, which will begin recording immediately

Once again, this is an MP4 file that can easy be shared and played on other devices.
