Hi all,
Think this is a pretty simple problem, but I've been thinking about it for a few days. Let's say that I'm going to have to output the contents of a file as the body of a mailx message.
I'll probably do this: cat <filename> | mailx <extra commands>
However, how do I go about doing... (1 Reply)

Hello,
I'm trying to run a program on a directory (traverse sub dirs too) through my csh script. Arrays support in CSH is appalling, something like associative arrays would have helped me do this so much easier.
Anyway, I want to hold some details extracted from the program and then at the... (0 Replies)
I have these

That's I... (3 Replies)

Alright, so I'm writing a file for the lexical analyzer (lex). It will be used to check C code (collecting the identifiers and storing those names along with the line numbers the identifier was found on). I'm not used to 'C' so I'm having some difficulty.
I am using a function (insertId()) to... (4 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.
