Help with CSH please

dev44 — Tue, 02 Jun 2009 10:02:06 GMT

I have the following script that works great in sh/ksh. Can someone please help me with the syntax for csh. I can't get the if statement working.

Thanks

# custom code for denying generic account login
if logname > /dev/null 2>&1
then
LGNM=`logname`
if egrep "^${LGNM}$" /etc/not_loginable > /dev/null 2>&1
then
echo "\nDirect login not allowed for $LGNM\n"
echo "\nNO remote login allowed for $LGNM (`date '+%D %T'`)\n" |
sleep 3
logger -p user.err NOT_LOGINABLE
exit 1
fi
fi

Why csh?

man csh

"fi"? Try "endif".

man csh

And that's not the only thing you'd need to
change. For example:

> [...] 2>&1

The script is what I use to lock out "generic" accounts...so that they can only be "su'd" to. We have a few users who are csh and I need to make it work for those accounts

Hi:

> I have the following script that works great in sh/ksh

Then why in the ?!? In HP-UX the Posix shell is your standard. In AIX, Korn is the default; in Linux, the bash shell --- all cousins. Why would you want to rewrite it in the C-shell?

If you haven't read this, you should!
