Thanks again for your help above, much appreciated.
I'm now trying to use the eval statement as advised above before attempting an array.
Can anyone tell me what i'm doing wrong? I sort of understand the method behind the eval command but haven't been able to use it successfully with the below script...
It should be self explanatory what im trying to acheive, any help would be appreciated. Thanks!

I am fairly new to scripting. But I have been able to extract and format all of my information required into one file. My issue is that one character is on a separate line. I need to be able to add the character to the previous line.

Hi folks!
Kind of a noob question... from an OLD AIX/HPUX Admin.
I am writing a script to ease use of a command; an extended aliasing if you will. What I want to do is set several variables (OPT1, OPT2, etc) with command arguments, such as --help, --list-all, etc. Later in the script, I... (5 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.
