Hi
Could be stupid, but I can figure out... I have a script that downloads a file from a http server ( virus definitions file ). The thing is that when I run it from the console (bash) works fine, but when I put it in the root's cron it doesn't, and it generates a core file.

Hi,
I have trouble with quotations of the M4 preprocessor.
I want to write a basic makro that removes all spaces and newlines at the end and at the beginning of a string.
I tried this:
define(`TRIM_END', `patsubst(`$1', `\(\\n\| \)*$', `')')
define(`TRIM', `patsubst(`TRIM_END(`$1')',... (0 Replies)
Dear Friends,
I am having a crazy issue with ftp.
I am doing 'mput' of 4 files (z1, z2, z3, z4) as below. But ftp transfers only every alternative file !! - ie; If I do mput z* for above, it sends only z1 and z3. Note that all the files are same and I tried this for several dummy files. All... (3 Replies)

Hello All,
was looking at a script wrote by someone and when I try and run it in ksh it gives me an error. Could ksh version be a problem or is there something wrong that I'm missing, when I run it from the command line it works. Thanks!

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.
