I am having the worst time trying to figure out this simple little script and I'm about to go nuts.
I have to use csh to create this script for a class and the problem I run into is checking my number range, just validating that the number is between 1 and 9 inclusive. I tried:
But it gives me a file redirection error message and I understand why, my brain is just quitting on me in trying to figure out how to fix it. Any help would be greatly appreciated!
Hi
I have always used ksh in the past, but now am using csh. To zero a file using ksh, you simply > filename. What is the command to do the same using csh?
Thanks in advance. (3 Replies)
I created a simple script and attempted to run it. All that the scrip contained was "ls -l".
At first I received the message "ksh: run_dir: not found"
I then tried typing "csh run_dir" This time the script worked.
typing echo $SHELL produced /bin/ksh
I would like to understand why this... (4 Replies)

I am using this code
echo "opt_tpath = $opt_tpath"
if ($opt_tpath == 1) echo " -tpath = $Atpath\n"
and is giving
opt_tpath = 0
Atpath: Undefined variable.
Atpath should only be printed in opt_tpath == 1 but it still tries to print.

LEARN ABOUT SUNOS
goto
exit(1) User Commands exit(1)NAME
exit, return, goto - shell built-in functions to enable the execution of the shell to advance beyond its sequence of steps
SYNOPSIS
sh
exit [n]
return [n]
csh
exit [ ( expr )]
goto label
ksh
*exit [n]
*return [n]
DESCRIPTION
sh
exit will cause the calling shell or shell script to exit with the exit status specified by n. If n is omitted the exit status is that of
the last command executed (an EOF will also cause the shell to exit.)
return causes a function to exit with the return value specified by n. If n is omitted, the return status is that of the last command exe-
cuted.
csh
exit will cause the calling shell or shell script to exit, either with the value of the status variable or with the value specified by the
expression expr.
The goto built-in uses a specified label as a search string amongst commands. The shell rewinds its input as much as possible and searches
for a line of the form label: possibly preceded by space or tab characters. Execution continues after the indicated line. It is an error to
jump to a label that occurs between a while or for built-in command and its corresponding end.
ksh
exit will cause the calling shell or shell script to exit with the exit status specified by n. The value will be the least significant 8
bits of the specified status. If n is omitted then the exit status is that of the last command executed. When exit occurs when executing
a trap, the last command refers to the command that executed before the trap was invoked. An end-of-file will also cause the shell to exit
except for a shell which has the ignoreeof option (See set below) turned on.
return causes a shell function or '.' script to return to the invoking script with the return status specified by n. The value will be the
least significant 8 bits of the specified status. If n is omitted then the return status is that of the last command executed. If return
is invoked while not in a function or a '.' script, then it is the same as an exit.
On this man page, ksh(1) commands that are preceded by one or two * (asterisks) are treated specially in the following ways:
1. Variable assignment lists preceding the command remain in effect when the command completes.
2. I/O redirections are processed after variable assignments.
3. Errors cause a script that contains them to abort.
4. Words, following a command preceded by ** that are in the format of a variable assignment, are expanded with the same rules as a vari-
able assignment. This means that tilde substitution is performed after the = sign and word splitting and file name generation are not
performed.
