If you just want some improvements to the existing script, I would recommend:
Improvements:
Use shell to expand $SourceLocation/* not a sub-shell + ls command.
Ignore sub-directories or other special files within the script directory.
Quoted $file references to cater for white space in file names.
Avoid unnecessary eval call for security reasons.

I have this Korn shell script that runs via a cron entry. It runs in a loop "watching" a specific file system for files with a certain name. The file system that it is watching is an upload file system for an FTP server. When files that are the correct name come in, it takes the extension of the... (1 Reply)

I'm learning bash and have discovered that the shell can only work with integers and not decimals.
I'd like to run my scripts in korn to account for this, but just now, when I tried to run my script, I got an error message that said 'no such file or directory,' even though when I'm in the shell... (3 Replies)

escape
escape(1) Mail Avenger 0.8.3 escape(1)NAME
escape - escape shell special characters in a string
SYNOPSIS
escape string
DESCRIPTION
escape prepends a "" character to all shell special characters in string, making it safe to compose a shell command with the result.
EXAMPLES
The following is a contrived example showing how one can unintentionally end up executing the contents of a string:
$ var='; echo gotcha!'
$ eval echo hi $var
hi
gotcha!
$
Using escape, one can avoid executing the contents of $var:
$ eval echo hi `escape "$var"`
hi ; echo gotcha!
$
A less contrived example is passing arguments to Mail Avenger bodytest commands containing possibly unsafe environment variables. For
example, you might write a hypothetical reject_bcc script to reject mail not explicitly addressed to the recipient:
#!/bin/sh
formail -x to -x cc -x resent-to -x resent-cc
| fgrep "$1" > /dev/null
&& exit 0
echo "<$1>.. address does not accept blind carbon copies"
exit 100
To invoke this script, passing it the recipient address as an argument, you would need to put the following in your Mail Avenger rcpt
script:
bodytest reject_bcc `escape "$RECIPIENT"`

BUGS
escape is designed for the Bourne shell, which is what Mail Avenger scripts use. escape might or might not work with other shells.
