how to make this work
hi,
I have been trying to make my script work but could not, tried some of the suggestions from here but I am not getting the correct result.
I have a script that was
Param1 ="$1"
Param2 ="$2"
$Script1 log -t "$param1" "$param2" | grep operation > /dev/null || {
echo "Message" >&2
exit 1 }
exit 0
Now I need to introduce a function in place of grep operation
something like
{
awk ' / dgdg/
..
END {
if(condition)
{
I should exit out like Exit 0
}
else
{
I am unable to pull in the operation
|| { echo "Message" >&2 exit 1}
}
}'
}
Please suggest how we can get

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"`
SEE ALSO
avenger(1),
The Mail Avenger home page: <http://www.mailavenger.org/>.
BUGS
escape is designed for the Bourne shell, which is what Mail Avenger scripts use. escape might or might not work with other shells.
