In Linux, you can use the command-line utility “xclip” to copy a file to the clipboard.
Here’s an example of how to copy a file called “file.txt” to the clipboard:
xclip -sel clip < file.txt
This command uses the xclip utility to copy the contents of the file “file.txt” to the clipboard. The “-sel” option specifies the selection to use, in this case “clip” for the clipboard.
You can also use “xsel” instead of “xclip” and it works the same way, for example:
xsel -b < file.txt
Please note that these commands are for a basic usage and you should adapt them according to your specific requirements. Also, before making any changes, it’s recommended to have a backup plan in case something goes wrong, and also to test the changes before applying them to your production environment.
Additionally, you can use other command-line utilities like “pbcopy” and “xsel” depending on your Linux distribution and requirements. Also, some GUI based file managers also have the feature to copy a file to the clipboard, you can check the documentation of the file manager you are using.
