When logged in as root if I type "env" there are a bunch of environment settings including one for CLASSPATH. However, I ran a cron script that ran this command "env > cronEnv". I noticed that the environment variables were entirely different inside the script. There wasn't even a CLASSPATH... (2 Replies)

ping -c 1 192.168.1.20 > ~/onlinestatus.txt
So, the script is called "status", it's executable, and in the correct path, etc. In a terminal window (I'm using Mac OS X), I can type status, and it will create... (4 Replies)

This has to be the ultimate newbie question...
I have a script that works well. To run it, I cut and paste it into a putty session.
Is there a way to put the script into a file and just run that file -- like a DOS batch file?
I'd like to schedule the file to run daily.
Thanks,... (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.
