 screendump - dump the contents of a virtual console to stdout 

You’ll need root privileges to run screendump, so use sudo.

You can use script. It will basically save everything printed on the terminal in that script session.

script makes a typescript of everything printed on your terminal. It is useful for students who need a hardcopy record of an interactive session as proof of an assignment, as the typescript file can be printed out later with lpr(1). You can start a script session by just typing script in the terminal, all the subsequent commands and their outputs will all be saved in a file named typescript in the current directory. You can save the result to a different file too by just starting script like: 

script output.txt To logout of the script session (stop saving the contents), just type exit.

$ script output.txt Script started, file is output.txt $ ls output.txt testfile.txt foo.txt $ exit exit Script done, file is output.txt 

$ cat output.txt Script started on 2020-07-23 09:57:16+05:30 $ ls output.txt testfile.txt foo.txt $ exit exit Script done on 2020-07-23 09:57:34+05:30

Copying text from a terminal

Most mature terminal emulators permit users to copy or save their contents.

General approach

In graphical terminal emulators, contents are typically selectable by mouse, and can then be copied using the context menu, Edit menu or a key combination such as Ctrl+Shift+c .

Terminals without CLIPBOARD selection

Xorg

Some emulators do not support the CLIPBOARD selection natively, and copy data to the PRIMARY selection. For them xclip may be used:

$ xclip -o | xclip -selection clipboard -i

The above command reads data from the PRIMARY selection and writes it to CLIPBOARD selection.

Other clipboard managers such as autocutsel provide automatic synchronization between selection buffers.

Wayland

Utilities like wl-clipboard and clipboard AUR can copy data to the Wayland clipboard:

Intercepting commands output

Use tee to intercept the output of a command.

$ command 2>&1 | tee output-file

After the command is executed, output-file will contain its output, while having displayed the output at the same time.

Accessing Linux terminal backlog

The backlog of a native terminal named /dev/ttyN may be accessed via /dev/vcsN . Hence, if one is working in /dev/tty1 , the following snippet will let store the backlog in a file output-file :

Comparison of common emulators

The factual accuracy of this article or section is disputed.

Unless the «Key combination» column states otherwise, the key combination is Ctrl+Shift+c .

Emulator	Select to PRIMARY	CLIPBOARD
		Key combination	Context menu	Window menu	Select
Alacritty	Yes	Yes	No	No	No
aterm AUR	Yes	No	No	No	No
eterm AUR	Yes	No	No	No	No

xfce4-terminal	Yes	Yes	Yes	Yes	No
xterm	Yes	Optional[1]	No	No	Yes
Yakuake	Yes	Yes	Yes	No	Optional

Special cases

putty

The xclip approach works for putty: one just has to remember that the xclip invocation should be done on the local computer (in another terminal), not on the remote machine to which putty is connected.

urxvt

Selecting text to CLIPBOARD requires the selection-to-clipboard perl extension. See rxvt-unicode#Cut and paste for details.

xterm

Access to the CLIPBOARD selection in xterm requires additional steps.

mlterm

In addition to Ctrl+Shift+c , you can use Ctrl+Insert if you do not want to kill processes accidentally.

The Linux cp Command – How to Copy Files in Linux

Dillion Megida

There are a couple different ways to copy and paste content when you’re working on your computer.

If you spend more time in the user interface of your device, you’ll probably use your mouse to do this. You can copy files by right-clicking on the file and selecting «Copy», then going to a different directory and selecting «Paste».

For my terminal friends, you can also perform file copy-paste operations without leaving the terminal. In a Linux-based terminal, you do this using the cp command.

In this article, I’ll explain what the cp command is and show you how to copy and paste files and directories in Linux using the terminal.

What is the cp command?

You use the cp command for copying files from one location to another. This command can also copy directories (folders).

The syntax of this command is:

cp [. file/directory-sources] [destination] 

[file/directory-sources] specifies the sources of the files or directories you want to copy. And the [destination] argument specifies the location you want to copy the file to.

To understand the rest of this article, I will use this folder structure example. Let’s say a directory called DirectoryA has two directories in it: DirectoryA_1 and DirectoryA_2. These subdirectories have many files and sub directories in them.

I’ll also assume you’re currently in the DirectoryA location in the terminal, so if you aren’t, make sure you are:

How to copy files with the cp command

If you want to copy a file, say README.txt from DirectoryA_1 to DirectoryA_2, you will use the cp command like this:

cp ./DirectoryA_1/README.txt ./DirectoryA_2 # ./DirectoryA_1/README.txt is the source file # ./DirectoryA_2 is the destination 

If you want to copy more than a file from DirectoryA_1 to DirectoryA_2, you will use the cp command like this:

cp ./DirectoryA_1/README.txt ./DirectoryA_1/ANOTHER_FILE.txt ./DirectoryA_2 

As you can see, you will put all the source files first, and the last argument will be the destination.

How to copy directories with the cp command

By default, the cp command works with files. So if you attempt to copy a directory like this:

cp ./DirectoryA_1/Folder/ ./DirectoryA_2 

You will get an error stating:

./DirectoryA_1/Folder/ is a directory

To copy directories, you have to pass the -r flag. This flag informs the cp command to recursively copy a directory and its contents (which could be files or other sub directories). So for the previous command, you can add the flag before the directory sources like this:

cp -r ./DirectoryA_1/Folder/ ./DirectoryA_2 

This command will recursively copy the Folder directory in ./DirectoryA_1/ as well as all files and directories in the Folder directory.

How to copy files that match a glob pattern

A glob pattern is similar to Regex, which allows you to match multiple files with names that match a specific pattern. Learn more about the difference here: Regex vs Glob patterns.

For example, if you want to copy all files in DirectoryA_1 with the .txt extension, you can execute this command:

cp ./DirectoryA_1/*.txt ./DirectoryA_2 

./DirectoryA_1/*.txt matches files with the .txt extension in their names, and the cp command can copy all those files to the destination.

You can check out the glob documentation to learn more about globbing patterns and characters you can use.

Now you know how to copy files (and directories) right from the command line. Thanks for reading!

How to copy files via terminal?

1) By using -i for interactive you will be asked if you would like to replace the file:

cp -i /home/levan/kdenlive/untitelds.mpg /media/sda3/SkyDrive/ 

or you can use -b to create a backup of your file:

cp -b /home/levan/kdenlive/untitelds.mpg /media/sda3/SkyDrive 

2) Same as the above:

cp (-i or -b) /media/sda3/SkyDrive/untitelds.mpg /home/levan/kdenlive 

3) Use -R for recursive and -i for interactive:

4) This last one can be done via the mv command, move is like cutting:

mv -i ~/MyFile ~/OtherFolder/MyFile 

if you want to move a directory, use:

mv -Ri ~/MyDirectory ~/OtherDirectory/ 

@WarriorIng64 you can use four spaces identation for code blocks, or you can surround small pieces of code with `s.

@WarriorIng64 That is triggered by the bash tag in the question. highlighting will be enabled by default by the system. If you answer a question with bash tag, the hightlighting will follow bash style and so on.

@Anwar I was just partway through making a Meta post on this when I saw your comment. Of course, I credited you in the answer. 🙂

When ~/Dropbox/RECENT/ is your current directory:

And I want to copy input.txt with another name in my current directory.

Again with ~/Dropbox/RECENT/ as current directory:

Existing filenames can be auto-completed using TAB .

Long version of the same copy command (when you are not in ~/Dropbox/RECENT/ ):

cp /home/$USER/Dropbox/RECENT/input.txt /home/$USER/Dropbox/RECENT/SORT/ 

I put a / behind every directory. If SORT does NOT exist a cp will also create a file named SORT making you think something went wrong. Adding the / will have cp error out and not copy the file.

Copying a file something.txt to file folder : use cp something.txt folder/

Copying a file something.txt to the current directory as something2.txt : use cp something.txt something2.txt
