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  speci‐
       fied,  it  is  compared to the uncompressed contents of file1.gz.  If two files are speci‐
       fied, their contents (uncompressed if necessary) are fed to cmp or diff.  The input  files
       are not modified.  The exit status from cmp or diff is preserved.

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