NAME
gzcmp, gzdiff - compare compressed files SYNOPSIS
gzcmp [ cmp_options ] file1 [ file2 ] gzdiff [ diff_options ] file1 [ file2 ] DESCRIPTION
gzcmp and gzdiff are used to invoke the cmp or the diff program on compressed files. All options specified are passed directly to cmp or diff. If only 1 file is specified, then the files compared are file1 and an uncompressed file1.gz. If two files are specified, then they are uncompressed if necessary and fed to cmp or diff. The exit status from cmp or diff is preserved. SEE ALSO
cmp(1), diff(1), gzmore(1), gzgrep(1), gznew(1), gzforce(1), gzip(1), gzexe(1) BUGS
Messages from the cmp or diff programs refer to temporary filenames instead of those specified. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +--------------------+-----------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +--------------------+-----------------+ |Availability | SUNWgzip | +--------------------+-----------------+ |Interface Stability | External | +--------------------+-----------------+ NOTES
Source for gzip is available in the SUNWgzipS package. GZDIFF(1)
