Top Forums UNIX for Dummies Questions & Answers Strip out number from wc output? Post 302910359 by neutronscott on Wednesday 23rd of July 2014 09:43:07 PM

so the output seems to be of only 1 wc command? $() will only strip the last \n. it sounds like a \r but wc shouldn't output that. is this Windows or Cygwin?

if you do
Code:
echo "$(wc -l file) $(wc -l file)" | cat -e

do you get
Code:
0 file^M0 file$

if so try replacing wc with a function that'll strip that
Code:
wc() { command wc "$@" | sed 's/\r//'; }
