Re: Bug with tcsh? : if evaluating true instead of false
I appreciate the help thanks! Sure, I'll send the script to you in an individual email instead of as an attachement to the list. Should anyone on the list want a copy, just drop me an email. I'd appreciate the script though, definitely, as any resource I have to learn all Unix script languages properly will only help in my becoming a better Unix admin as well as script more common tasks to help make my life a bit easier. When I've started to write shell scripts, I read a nice book which covered sh, csh and ksh with lots of examples. That was the first edition, but it's now in it's fourth edition and now have coverage of bash and tcsh plus you get info on sed awk.

There are a lot of sites on the topic. I would select one from a University. Have fun!

Bug with tcsh? : if evaluating true instead of false
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1
Ok, so I tried to make a simple script to add users so I wouldn't have
to type in groups/pw over and over again... the problem is that it's not
behaving like it should =o.
Script:
#!/bin/tcsh -x
#
if ( ( $# != 0 ) ) {
set GROUPS=;
set USER=;
if( ( $# == 2 ) ) {
set USER=$1;
set GROUPS=$0;
switch($0)
case -v:
set GROUPS=-G vip;
breaksw
case -w:
set GROUPS=-G vip,wheel;
breaksw
default:
echo bad argument(s) specified!;
exit(1);
endsw
} else if($# == 1) {
set USER=$0;
} else {
echo bad # of args; exiting..;
}
`pw add user -N -d /home/$USER -s /usr/local/bin/bash $GROUPS
$USER mkdir /home/$USER ln -s /home/dud.bash_login
/home/$USER/.bash_login`;
} else {
print Usage [-r|-v|-w] username
}
Output:
[EMAIL PROTECTED] ~]# ./mkuser
if ( ( 0 != 0 ) ) {
set GROUPS=
set USER=
if ( ( 0 == 2 ) ) {
set USER=
set GROUPS=./mkuser
switch ( ./mkuser )
echo bad argument(s) specified!
bad argument(s) specified!
exit ( 1 )
Basically it should drop out at the first if statement due to 0 != 0
being true and go straight to the else block, but it's falling through
to the switch statement. Any ideas?
Also..

Duh... tcsh syntax != C/C++ or Java syntax. Silly me... lol.

I usually do stuff in either bash or csh, depending on the level of difficulty, but try to use tcsh for all FreeBSD scripts on my system since tcsh is included as a part of the base system. Plus, I do like tcsh better in some ways because the syntax is similar to C/C++ and Java, but as you saw if I get in a programming funk with either of the 3 beforementioned languages, it's fun remembering language semantics sometimes :). I'd appreciate the script though, definitely, as any resource I have to learn all Unix script languages properly will only help in my becoming a better Unix admin as well as script more common tasks to help make my life a bit easier.

Got that done with /etc/login.access by adding: - -ALL except wheel:ALL Now since I mentioned it though I was wondering, does this create issues for secondary daemon accounts (www, mysql, etc)?
