NR is the Number of Records. If the NR (Number of Records) is equal to 1 then that is the first line. The first line being the first row testing for NR==1 is a pattern match that matches the first line only. Then a small optimization is to exit immediately so as not to read any of the rest of the input. viosvrcmd -m Server-XXXXXXX -p va10XXX-VIOS2 -c "lsmap -all -npiv" | awk 'NR==1{print$1;exit}' > Please guide us to get only vfchostX column alone.Thanks... > > hscroot@vahmc032:~> viosvrcmd -m Server-XXXXXXX -p va10XXX-VIOS2 -c "lsmap > -all -npiv" | grep -i va10XXX > vfchost46 U9117.MMC.10E45C6-V2-C180 15 va10XXXXX AIX > > Note: awk '{print $1}' is not working. These types of shell scripting questions are probably better sent to the help-gnu-utils@gnu.org discussion mailing list. Email there won't open a bug ticket. That is generally the best place for random scripting questions using the utilities. Since this ticket has already been started please continue the conversation here for this discussion. Please keep 22886@debbugs.gnu.org in the recipient list for this topic. Bob
