Variable present or not, syntax question....

cameleon666 · 11-19-2008, 12:25 PM

if [ find /etc/httpd/conf.d/ -type f -exec grep -l 'redcube' {} \ ];
then
echo "Variable present"
else
echo "Adding Variable"
echo Include /etc/httpd/conf.d/redcube.include >> /etc/httpd/conf.d/zz010_psa_httpd.conf
fi

How to correct it, when string redcube found just show variable present if not add it at end of file.

Correct what?? What's your question, and what are you trying to do, and what's not working? On what version/distro of Linux? Please clarify.

i believe you want to use "$?" which is a system variable that contains a number based off the *last* commands success.

here is some code i wrote last year making use of the $? var

Code:

        while read line 
        do
            inputfile=`echo $line |cut -d\| -f3 |cut -c1-6`
            grep ${inputfile} ${TEMPDIR}/bleh.run.tmp > /dev/null
            if [ $? != 0 ]; then
                grep $inputfile ${TEMPDIR}/bleh.tmp  | head -1 >> ${TEMPDIR}/blehReadyToGo.tmp
            fi
        done < ${TEMPDIR}/bleh.tmp

thx guys

well i want to make a script that will read file zz010_psa_httpd.conf file and search for redcube text, if this text is found script will exit, if there are no redcube text in that file it will add other text - at end of this file.

sorry for my english...

this script will run by cron everyday.

Code:

#!/bin/bash

zz010="/path/to/zz010_psa_httpd.conf"

cat $zz010 |grep redcube > /dev/null
if [ $? != 0 ]; then
     echo "redcube" >> $zz010
fi

explanation... assign the path to your file to the variable zz010.

cat the variable (which is really your file), and grep for the word "redcube", and send any output to /dev/null (deletes it)

if the last command was successful, do nothing and exit the program.

if the last command failed, append the word redcube to the variable $zz010
