I want to write an interactive line in a C-shell script which asks the operator if he/she wants to continue - something like :
"Do you want to continue ? [y]es/[n]o: "
set answer=($<)
when I try to test answer
if ($answer =~ [yY])
it returns me no match - I have tried also with [Y][y] and also with == operator,
where am I wrong? I must wite it in csh - this is the used shell for this user.
Thank you,
ionut

Re: C-shell script
just for test,
what is the content of $answer?
Try visualizing it with a
set -x
at the beginning of the script. Honestly i do not know what the sintax " $< " means...
Maybe using a
read answer
will do the trick.

Re: C-shell script
this syntax set a=($<) is proposed in "Shells: User's guide" book from HP for interactive shell-scripts for c-shell.
just for test: when I type y as answer it returns me:
y =~[Yy] no match
