In the Korn Shell (ksh), I'm trying to set my PS1 to include my system-
name and userid as amdahl!krs and no matter how I quote the
exclamation, it gets interpreted as the command process number. I even
tried saving the desired string in another variable and just including
the variable in the PS description. Samples:
PS1='amdahl"!"krs ...' or PS1='amdahl"\!"krs ..."
gives
amdahl123krs ... or amdahl\123krs ...
----------------------------------------------------------
MYLOC='amdahl!krs' or MYLOC='amdahl\!krs'
PS1='$MYLOC ...' PS1='$MYLOC ...'
also gives
amdahl123krs ... or amdahl\123krs ...
----------------------------------------------------------
How can I get a real printable exclamation into a Prompt String????
Thanks.

Try: PS1="amdahl!!krs " It seems that to "escape" the exclamation mark, use another exclamation mark. -- Harold Bamford AT&T Bell Labs IE 2F-524 (312) 369-7397

I thought that there must be a way to do this, but when I tried lots of variations (in addition to the ones Kris tried) I still came up empty. Therefore I checked out the source to ksh and voila! I found the answer. The way to get a "!" in a prompt string is to put two of them in. The command: PS1="popeye!!sherm" leads to the prompt "popeye!sherm". This works on the most recent version of ksh (06/03/86) but the source as far back as 06/84 indicates it was treated the same way. Unfortunately I have found no indication of this in any ksh documentation. I am posting this followup rather than replying directly to Kris since I think others may be interested too (if only for curiosity's sake). -- Paul Sherman AT&T Information Systems, Lincroft, NJ {pegasus|ihnp4}!popeye!sherm (201) 576-6316

Do this: PS1="amdahl!!krs " # TWO !'s The extra space at the end makes long prompts easier on the eye. If you don't want it, you don't need the "'s. The two-! feature is (to the best of my knowledge) undocumented. It was a lucky guess on my part. Any comments, Dave (congrats on the DMTS)? -Ed Horch ihnp4!cord!ebh
