In my examples, I meant to say "looking for first field" and "looking for 5th field" rather than record... sorry for any confusion use awk -F: '{ print $1 }'

gawk fails on first record (remaining records are OK) if using an FS value of anything but the default (of space). I have generated input files and tested with a variety of FS values and the first record ALWAYS returns the entire record as $1 and doesn't break it down into the appropriate fields. Remaining records return as expected. First record only $1 has a value (of the whole record) and remaining fields are null. I can duplicate this error under redhat 5.2, 6.1 and 6.2, and using a variety of different FS values, including ":" (documented below), "/", "a" and several other values. Example: input file: cat /etc/passwd root:x:0:0:root:/root:/bin/bash bin:x:1:1:bin:/bin: daemon:x:2:2:daemon:/sbin: looking for first record: cat /etc/passwd | gawk '{FS=":"}{print $1}' root:x:0:0:root:/root:/bin/bash bin daemon looking for 5th record: cat /etc/passwd | gawk '{FS=":"}{print $5}' <<--this field returned nothing except an output record seperator, --I would have expected the word "root" bin daemon
