Have been watching a number of crackme-type walk-throughs, where the speaker relies heavily on xclip to capture a command line output so that the mouse can be used to paste data into the browser. I could never get it to work with Chrome, until today.
To use xclip with Chrome, add the following to ~/.bashrc (or .bash_aliases if you have it):
alias xclip="xclip -selection clipboard"
After that, it should work as expected.
