Full Discussion: String editing using sed? awk?
Homework and Emergencies Homework & Coursework Questions String editing using sed? awk? Post 302370788 by peage1475 on Thursday 12th of November 2009 11:41:45 AM

ok here is what I am trying but it does not seem to work correcty
Code:
cat test1 | while read path
do
if cmp -s $path ./public_html/index.html
then
echo $path >> files
else
echo "working..."
fi
done

from my understanding cmp -s will produce either a 0, if the files are identical, or a 1 if the files are different. So my if statment says that if the files are different add $path to files, else prin working. why is this only producing working... when I know for a fact that there are at least 5 that are modified different then the one it is comparing too?

zdiff

ZDIFF(1)						      General Commands Manual							  ZDIFF(1)

NAME

       zcmp, zdiff - compare compressed files

SYNOPSIS

       zcmp [ cmp_options ] file1 [ file2 ]
       zdiff [ diff_options ] file1 [ file2 ]

DESCRIPTION

       Zcmp  and  zdiff are used to invoke the cmp or the diff program on files compressed via gzip.  All options specified are passed directly to
       cmp or diff.  If only file1 is specified, it is compared to the uncompressed contents of file1.gz.  If two files are specified, their  con-
       tents  (uncompressed  if  necessary)  are  fed to cmp or diff.  The input files are not modified.  The exit status from cmp or diff is pre-
       served.

SEE ALSO

       cmp(1), diff(1), zmore(1), zgrep(1), znew(1), zforce(1), gzip(1), gzexe(1)

BUGS

       Messages from the cmp or diff programs may refer to file names such as "-" instead of to the file names specified.
