This may be little confusing. I have Script1, which pulls data from the system and creates another script(lets say script2). While I run script1 I need to add printf/echo statements for script2, so that when I run script2 I see those statement.
eg: script1 765
script2
I thought it would be something like this.
on script1

Hello script guru's
as i write more and more code i always block at managing output... either writing to standard out, writing to files via std out (log, temp file, etc). Don't get me wrong 99% of the time it DOES the job but maybe there is more efficient.

Hello
I want to check whether certain arguments were passed to the script, and when those are, not doing a log entry.
If those arguments are not passed, always do a log entry (*new call*).
What currently i have is this:

Hello,
For some reason i dont remember, i currently believe (but beeing unsure) that printf is available on more diffrent systems (unix, bsd, linux, ??) than echo is.

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"`

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.
