Top Forums UNIX for Dummies Questions & Answers Extract common data out of multiple files Post 302748029 by Scrutinizer on Monday 24th of December 2012 06:44:51 AM

If there is maximum of 1 entry per file:
Code:
awk '++A[$0]>=ARGC-1' file*

This would then be a bit more robust:
Code:
awk '{$1=$1} ++A[$0]>=ARGC-1' file*

But 1000 files is probably going to be too many for the command line length.

Otherwise try:
Code:
( 
  set -- file*
  for f
  do
    cat "$f"
  done | awk '{$1=$1} ++A[$0]>=c' c=$# 
)
