[SOLVED] Extract range of users with awk

kikinovak · 08-02-2014, 03:46 AM

Hi,

Here's a line using awk to extract "real" users on my system:

Code:

bash-4.2$ awk -F: '$3 > 999 {print $1}' /etc/passwd | sort
glagaffe
jktartempion
kikinovak
lgibaud
mshanseifan

Does anyone know how I can combine several conditions? I would like, for example, to extract only users with an UID between 1000 and 2000. In other words, $3 > 999 and $3 < 2000. I can't seem to find the correct syntax for that.

Cheers,

Niki

awk -F: '$3 > 999 && $3 < 2000 {print $1}' /etc/passwd | sort

Thanks very much. I just found it out by myself. Just a matter of replacing & by &&. I really should wait until I wake up completely before undertaking this sort of task. Anyway, SOLVED.

San Marco coffee in a Riviera espresso machine, FYI.

So that's why you woke up so quickly!
