NOt very structured data, but what the hey! Middle file could be reworked into a shell case statement as a dynamic psart of a parent script. Using shell 'while read a b c' command, the three fields can be loaded into three variables, the first applied to the dynamic case statement that prints the desired output with the third.
Code:
#!/bin/bash
zcase="case \$a in
$( while read x
do
echo "(*$x*)
echo $x \$c
;;"
done <$1 )
esac"
while read a b c
do
$zcase
done
Assumes file1 on stdin, file 2 on command line and file 3 output is stdout.
I'm trying to find files which have urls such as "services/amf/fri/home.html" and "services/amj/fri/air.html" - so the pattern I want to match with grep, logically, is one that has

3. ending in "html"

The clear command specifically says it can only clear the entire terminal display. There are no arguments. So I'm wondering if there are any work arounds.
Carriage return does not work for this as it only moves the cursor to the beginning of the line we're on. And obviously NL only goes down. If... (1 Reply)

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.
