zdiff
ZDIFF(1) BSD General Commands Manual ZDIFF(1)NAME
zcmp, zdiff -- compare compressed files
SYNOPSIS
zcmp [options] file [file2]
zdiff [options] file [file2]
DESCRIPTION
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
specified, 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.
ENVIRONMENT
TMPDIR Directory in which to place temporary files. If unset, /tmp is used.
FILES
/tmp/zcmp.XXXXXXXXXX Temporary file for zcmp.
/tmp/zdiff.XXXXXXXXXX Temporary file for zdiff.
SEE ALSO bzip2(1), cmp(1), diff(1), gzip(1), xz(1)CAVEATS
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 (``-'')
