TMPDIR
Directory in which to place temporary files. If unset, /tmp is used.
zdiff1
Compare compressed files
Usage
zcmp [options]
file1
[file2]
zdiff [options]
file1
[file2]
Overview
zcmp and zdiff are filters that invoke cmp(1) or diff(1) respectively to compare compressed files. Such files generally have a “Z” or “gz” extension (both the compress(1) and gzip(1) formats are supported). 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.
Environment
Files
-
/tmp/zcmp.XXXXXXXXXX -
Temporary file for
zcmp. -
/tmp/zdiff.XXXXXXXXXX -
Temporary file for
zdiff.
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 (‘-’)
