shell script to call perl script problems
Ok, don't ask me why, but all calls to perl must be called by a shell script. Its really not ideal, but its what I have to work with.

Calling it isnt the issue, its passing in the arguments.

I have about 1000 perl scripts to call by a shell script. Right now, I'm executing the shell script and bringing in the entire perl script and its arguments as one string to be executed.

The shell script is simply

Code:
$*

However, when I call a perl script with its arguments, its fails many times because of the way the shell script is resolving the passed arguments. For example. Here's the shell script (callperl.sh) executing a perl script:

Code:
 
callperl.sh zipfile.pl "/tmp/last/done*.txt"

When it gets executed by the shell script, the parameter of "/tmp/last/done*.txt" gets resolved as all the files that matches the regex. This caused the perl script to failed because its exepecting the argument "tmp/last/done*.txt" and not a list of files. The

I've tried to encapsulate the arguments in various double quotes, tick marks, single quotes, etc. but cannot get the proper results.

Code:
 
callperl.sh zipfile.pl ""/tmp/last/done*.txt""
callperl.sh zipfile.pl \"/tmp/last/done*.txt\"
callperl.sh zipfile.pl '"/tmp/last/done*.txt"'
callperl.sh `zipfile.pl "/tmp/last/done*.txt"`



I'd like to have a single shell script that could call a perl scripts with any number of arguments, but have it resolve the arguments correctly because the number of arguments varies greatly. Not only that, but there are over 1000 perl scripts that need to be called this way. Is there a simple way to do this? What am I missing?

NAME

       sieveshell - remotely manipulate sieve scripts

SYNOPSIS

       sieveshell [--user=user] [--authname=authname] [--realm=realm] [--exec=script] server[:port]

       sieveshell --help

DESCRIPTION

       sieveshell allows users to manipulate their scripts on a remote server.	It works via MANAGESIEVE, a work in progress.

       The following commands are recognized:

	   list list scripts on server.

	   put <filename> upload script to server.

	   get <name> [<filename>] get script. if no filename display to stdout

	   delete <name> delete script.

	   activate <name> activate script.

	   deactivate deactivate all scripts.

OPTIONS

       -u user, --user=user
	   The authorization name to request; by default, derived from the authentication credentials.

       -a authname, --authname=authname
	   The user to use for authentication (defaults to current user).

       -r realm, --realm=realm
	   The realm to attempt authentication in.

       -e script, --exec=script
	   Instead of working interactively, run commands from script, and exit when done.
