In order to map the arrow keys to use history commands under the emacs
mode with ksh(1), please put the following lines in the
${HOME}/.kshrc:
# Arrow keys to use history commands under the emacs command edition mode.
alias __A=`echo "\020"` # mapping arrow key 'up'
alias __B=`echo "\016"` # mapping arrow key 'down'
alias __C=`echo "\006"` # mapping arrow key 'right'
alias __D=`echo "\002"` # mapping arrow key 'left'
alias __H=`echo "\001"` # mapping arrow key 'home'
There are two underline characters in alias commands.
To be able to get the PageUp and PageDown keys to work in vi(1), edit
the ${HOME}/.exrc file and insert the following lines:
" Mapping PageUp & PageDown keys.
map ^[[5~ ^B
map ^[[6~ ^F
Note: comment begin with a " in .exrc, not a #.
How to enter the ^[[5~ character? You have to type Control+V, then press the PageUp key.
How to enter the ^B character? You have to type Control+Vn then press the Control+B keys.
As a last tip, here is how to change the prompt using working directory
information. Using export PS1='${PWD} $ ', the behavior is as follow:
/home/jpeg $ cd
/home/jpeg $ cd /var/log
/var/log $
Using export PS1='${PWD##*/} $ ', the behavior is as follow:
jpeg $ cd
jpeg $ cd /var/log
log $
