Filtering /etc/passwd in Unix

I'd like to filter the content of /etc/passwd, only showing the lines for which the value in the third column is greater than 999.

Is there an easy way to do this with a one liner? I'd like to do it without writing a boring for-loop.

This is a simple way to do it:

awk -F: '$3 > 999' /etc/passwd

This uses awk with a field separator of : and instructs it to print the line if the third field is greater than 999. If you want to only print the first field (username) or construct some new lines based on the fields, this is a starting point:

awk -F: '{if ($3 > 999) print "user", $1, "uid", $3}' /etc/passwd
