Re: How to know when mc is running in a terminal

[Mike Smithson]

Thanks frank. The answer was in front of my nose the whole time.

Environment variable MC_TMPDIR can be used to know that you're being
called from mc. For some reason MC_SID disappears but MC_TMPDIR does
not.

I needed something more specific than just knowing whether I'm
in pts or not. I want to know if it's mc's F4 EDIT command calling, or
at least being called from a terminal with mc running in it.

if [ -n $DISPLAY -a -n $MC_TMPDIR ]; then
# we're being called from mc in XWindow terminal

Try the shell command 'tty'. In the Linux console it will reply e.g.  
/dev/tty1. In a graphic terminal the reply will be /dev/pts/0.

How to know when mc is running in a terminal

[Mike Smithson]

I have a specialized F4 script ($EDITOR) that I need
to know whether my editor is being called from mc or
not.

The MC_ env vars don't seem to exist when F4 is hit.

Question: how can a script know whether it is being
called from F4 in mc or just a terminal?

Thanks in advance.
