linux - Problem removing duplicate files using awk -

contents of part3.1.awk

{ current_line=$0 if (current_line!=prev) {     print $1 " -> " " -> " $5 " -> " $8 } prev=$0 }

to list of processes, run in terminal. want output removed duplicates , sorted too.

$ps -ef | awk -f part3.1.awk | sort

what wrong doing?

you sorting output awk script, when want sorting input.

$ps -ef | awk -f part3.1.awk | sort

should be

$ps -ef | sort | awk -f part 3.1.awk

but should tell you don't need awk remove duplicates. sort -u you, in

ps -ef | sort -u
