get the first column of each line as a parameter

melanie_pfefer · #1 (**permalink**) 07-22-2008

hi

I have a file with this format

server1

ort1
server2

ort2
server3

ort3

I already built a script that starts 1 server.

I want to add 'ALL' option to start all servers

how to do that (for loop? awk? sed....)

thanks for your help

What have you tried so far and where exactly are you stuck?
And please use code tags for your samples.

snippet:

Code:

INFILE="./myserverlist"

if [[ $1 = "ALL" ]]; then
   while read SERVER PORT; do
      echo ${SERVER} ${PORT}
   done < ${INFILE}
else
   echo "No or wrong parameter!"
fi

exit 0

Change the "echo" vs. your start syntax.
You can parse other parameters with optargs or witch case/esac.

EDIT: Sorry, yes, Danmero is right, I was a bit too fast. Please use tags and show what you got next time.
