Change script

ust3 — Wed, 07 Nov 2007 21:29:19 GMT

The below is the script to check the user no. , when user2 is login and run the script ($awk -F: -v me=$me '$1==me {print $2}' test.txt ) , the output is 2 .
$me=$(whoami)
$awk -F: -v me=$me '$1==me {print $2}' /tmp/test.txt
$2

The current test.txt is as below:
$vi test.txt
user1:1
user2:2
user3:3

now , if the test.txt is changed the format as below , can advise how to change my script to check the user no.

$vi /tmp/test.txt
user1 - 1
user2 - 2
user3 - 3

Hi ,

do you have the space between the user and the number ?
-- if no space then replace the -F: with -F- and it should work , so the full line will be

awk -F- -v me=$me '$1 == me { print $2}' /tmp/test1.txt

otherwise try this -- if you want the space

awk -v me=$me '$1==me {print $3}' /tmp/test.txt
