Hi Corona,
I wrote a complete script to fulfill my requirement [1]. It seems that I am making some mistake. It is throwing following error:
I guess, root based application does not need "exit 0", but then how shall I exit it.
All,
I want to run a non-root script as the root user with non-root environment variables with crontab. The non-root user would have environment variables for database access such as Oracle or Sybase. The root user does not have the Oracle or Sybase enviroment variables. I thought you could do... (2 Replies)
I'm writing an application (Progress language) that needs to:
1) load the contents of a cron table into the Progress application;
2) display this information in a human manner and allow a select group of people to update it (these people are logged in as themselves, not as root);
3) save... (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.
