NAME

     xzcmp, xzdiff, lzcmp, lzdiff - compare compressed files

SYNOPSIS

     xzcmp [cmp_options] file1 [file2
     xzdiff [diff_options] file1 [file2
     lzcmp [cmp_options] file1 [file2
     lzdiff [diff_options] file1 [file2

DESCRIPTION

     xzcmp  and  xzdiff  invoke  cmp(1)  or  diff(1)   on   files
     compressed   with  xz(1),  lzma(1),  gzip(1),  bzip2(1),  or
     lzop(1).  All  options  specified  are  passed  directly  to
     cmp(1)  or diff(1).  If only one file is specified, then the
     files compared are file1 (which must have a suffix of a sup-
     ported compression format) and file1 from which the compres-
     sion format suffix has been  stripped.   If  two  files  are
     specified,  then  they are uncompressed if necessary and fed
     to cmp(1) or  diff(1).   The  exit  status  from  cmp(1)  or
     diff(1) is preserved.

     The names lzcmp and lzdiff are provided for backward  compa-
     tibility with LZMA Utils.

BUGS

     Messages from the cmp(1) or diff(1) programs refer  to  tem-
     porary filenames instead of those specified.
