zcmp, zdiff -- compare compressed files
zcmp [options] file [file2] zdiff [options] file [file2]
zcmp and zdiff are filters that invoke cmp(1) or diff(1) respectively to compare compressed files. Any options that are specified are passed to cmp(1) or diff(1). If only file1 is specified, it is compared against a file with the same name, but with the extension removed. When both file1 or file2 are spec- ified, either file may be compressed. Extensions handled by gzip(1): o z, Z, o gz, o taz, o tgz. Extensions handled by bzip2(1): o bz, o bz2, o tbz, o tbz2. Extensions handled by xz(1): o lzma, o xz, o tlz, o txz.
TMPDIR Directory in which to place temporary files. If unset, /tmp is used.
/tmp/zcmp.XXXXXXXXXX Temporary file for zcmp. /tmp/zdiff.XXXXXXXXXX Temporary file for zdiff.
zcmp and zdiff rely solely on the file extension to determine what is, or is not, a compressed file. Consequently, the following are not supported as arguments: - directories - device special files - filenames indicating the standard input (``-'') BSD May 23, 2011 BSD
