Shell Programming and Scripting

'junk' is just a placeholder for fields in the '/etc/passwd' file we/you want to skip reading.
Make sure you copy/paste the code 'as-is' - you seem to be refering to 'useID' and not 'userID' as it's used in the code snippet.

thx for the quick reply

now i get

userID->[] username->[uucp]

copy/paste the line from the /etc/passwd file with 'uucp' on it, pls.

You understand that this was just a 'hint' how to do the mapping, doncha ya? You can assign any existing userID from your system to the 'userID' variable. Probably copy/pasting a couple of lines here help.....

yay it works, thank you vgersh99

here are a few line from the /etc/passwd

jasmeet.manik:x:1422:100:Jasmeet Manik:/home/jasmeet.manik:/bin/bash
pascal.morano:x:1423:100:Pascal Morano:/home/pascal.morano:/bin/bash
shan.luo:x:1424:100:Shan Luo:/home/shan.luo:/bin/bash
raeika.memari:x:1425:100:Raeika Memari:/home/raeika.memari:/bin/bash
shakirat.raji:x:1426:100:Shakirat Raji:/home/shakirat.raji:/bin/bash

its back to doing what it was doing before

am still a bit confused on how the link between the current processes and the /etc/passwd is achieved

given a snippet from /etc/passwd file
and the script:

Code:

#!/bin/ksh

userID='raeika.memari'

while IFS=: read userIDpasswd junk junk junk userName junk
do
   if [ "${userID}" = "${userIDpasswd}" ]; then
      echo "userID->[${userID}] userName->[${userName}]"
   fi;
done < /etc/passwd

I get the following output:

Code:

userID->[raeika.memari] userName->[Raeika Memari]

thx again.

how would i feed the usernames of the currently logged in users to the userID variable?
