Shell tips

Enable "vi mode" in your ksh shell and embrace the feeling of vi shortcuts:

echo "set -o vi" >> $HOME/.kshrc

In a new shell, you can navigate the history with Esc + j or k

Move the cursor in a long command with h or l

Search and filter the history with Esc + /

Vi lovers, see to add xcape -e 'Alt_L=Escape' & to your "$HOME/.xsession" file.
