Hi,
I have two files(file 1 file2), each contains one word in ecah line.
I am trying to get the words in file2 that are not in file1. saving
result in file3
I need equivelant awk command to the following grep
grep -F -x -v -f file2 file1 > file3
grep takes time and is beeing killed because file2 is about 40000 long
,and file1 is about 25000
if I would do c program, It would have two nested for that will take
time too.
please I will appriciate any suggestions.
From the description you have provided I would first try the Unix
command-line program 'comm'.
Try 'man comm' and look in particular at the '-3' option.
Thank you very much.
