Quick question, what do I add to what config file to make bash run
'clear' prior to executing whatever commands I run in the terminal?
Thanks in advance?
Add this to your ~/.bashrc:
preexec () { clear; }
preexec_invoke_exec () {
[ -n "$COMP_LINE" ] && return # do nothing if completing
local this_command=`history 1 | sed -e "s/^[ ]*[0-9]*[ ]*//g"`;
preexec "$this_command"
}
trap 'preexec_invoke_exec' DEBUG
