diff - Csh how to compare the content of two files in different sequence? -

-

need in comparing contents of 2 files (in different sequence , spacing) , output difference in csh. tried diff -w file1 file2, somehow doesn't work.

file1

cat white 123 dog brown 234 duck black 567 rat grey  345 fish blue 456

file2

fish               blue    456 rat                grey    345 dog                brown   234

output

cat white 123 duck black 567

thanks in advance.

you solve problem 2 steps:

  1. squeeze spaces , sort lines

    perl -w -ne 's/\s+/ /g; say' file1.txt | sort > file1.sorted.txt perl -w -ne 's/\s+/ /g; say' file2.txt | sort > file2.sorted.txt

  2. find out common lines in them

    comm -3 file?.sorted.txt
