INSERT
you can insert text from your host’s clipboard by pressing the right mouse button (default setting) or by pressing Shift + Ins. Note that this has the same effect as entering every character manually. So if you are using auto indentation in vim, this will very likely screw up your code.
To fix that, you can do the following:
Before pasting into vim, enable paste mode by entering :set paste.Press I to enter insert mode. The status bar should say -- INSERT (paste) -- now.Press Shift + Insert (The auto indentation of vim should not happen.)Press Esc to leave insert mode, and disable paste mode using :set nopaste again.

How to delete all lines of file in Vim

farbige man pages

Man pages sind nicht immer sehr übersichtlich. Die man pages etwas einzufärben hilft!

ans Ende der .bashrc

export LESS_TERMCAP_mb=$'\E[01;31m'
export LESS_TERMCAP_md=$'\E[01;31m'
export LESS_TERMCAP_me=$'\E[0m'
export LESS_TERMCAP_se=$'\E[0m'
export LESS_TERMCAP_so=$'\E[01;44;33m'
export LESS_TERMCAP_ue=$'\E[0m'
export LESS_TERMCAP_us=$'\E[01;32m'

schon sind die man pages in Farbe.

fun with chmod

Fun thing to do as root, in root: chmod -R 666 * Just as bad as rm -rf *, but more fun. “The files are all there, but I can’t do anything with them!” And you can’t change permissions, since chmod isn’t executable either. :-)
