- Also this works for title strings, it is no solution for those of
- us, who want to include escape sequences _INTO_ the prompt.
- I like to have the host name included into the prompt string
- and highlighted by inverse video. So my prompt is defined as:
-
- ME=`logname`
- if [ -w /etc/passwd ]
- then PCH="#"
- else PCH=">"
- fi
- SMSO=`tput smso`
- RMSO=`tput rmso`
- PS1="$ME@$SMSO\h$RMSO:$TERMLINE \w \!$PCH "
-
- I have omitted the code to determine $TERMLINE (which will be
- usually something like 'tty05'), because it is somewhat nasty
- and has nothing to do with problem here.
