cmd=`echo $line | awk -F ‘;’ ‘{print $1}’`
count=`$cmd`

The variable cmd is storing the results of a command because you have the command encapsulated by backticks “. Based on this information it seems like you are doubling your work. I would modify as follows.

cmd=`echo $line | awk -F ‘;’ ‘{print $1}’`
count=”$cmd”

or

count=`echo $line | awk -F ‘;’ ‘{print $1}’`

If you really need it setup this way, use double or single quotes to encapsulate the command defined by cmd.

cmd=”echo $line | awk -F ‘;’ ‘{print $1}’”

I have not had luck storing commands that contain awk in a variable and calling it later. I usually use a function.

cmd () {
echo $line | awk -F ‘;’ ‘{print $1}’
}

count=`cmd`

CMD=’ps -elf|grep vnc’
eval $CMD

Thanks to all

Thanks a lot hanish

I am trying to execute some list of commands.So,I have added my commands inside a csv file.I am trying to read that command and execute the command and store the result of the command in the variable.

cmd=`echo $line | awk -F ‘;’ ‘{print $1}’`
After this “cmd” gets the value like “cat filename | wc -l ”

I am trying to store in a variable like this
count=`$cmd`.

Since there is a pipe i am getting error.
Can some one help me on this

CMD=’ps -elf|grep vnc’
eval $CMD

Thanks to all

CMD=’ps -ef|grep vnc’

Help me out…

You’ll be sorry when to look at the script a few months from now.

echo "done"


I want to take tar-backup of user home folders on RH9 Linux.

My short script is as follows :

#!/bin/bash
#pwd
cd /home
tar cvzf /backup/archive/usr1-`date +%C%y%m%d`.tar.gz usr1
tar cvzf /backup/archive/usr2-`date +%C%y%m%d`.tar.gz usr2
.
.
So On !!!!!!!!!

If i am running this script from cmd , it works fine. But If i cron the job it stops aborted on 2nd directory itself with half-completed tar file.
How to solve this problem? I am not so novice in Linux. Pls help.
