náhrada preexec v bashi (bohužel mi to funguje jen v bash-3.1)

$ cat ~/.bashrc 
...
# xterm title ('user@host pwd' in title, 'pwd' in icon)
if [ "$TERM" = xterm -o "$TERM" = rxvt ]; then
        PS1="$PS1"'\[\e]2;\u@\h \w\a\e]1;\w\a\]'
        # current command in xterm title ('user@host pwd [command]')
        # bash-2.05b doesn't have BASH_COMMAND, bash-3.0 has it, but it's broken
        trap 'bash_command_works="$BASH_COMMAND"' DEBUG
        trap DEBUG
        if test "$bash_command_works" = 'trap DEBUG'; then
                trap 'echo -ne "\\e]2;$LOGNAME@$HOSTNAME ${PWD/$HOME/~} [$BASH_COMMAND]\\a"' DEBUG
        fi
fi
