NAMEzcmp, zdiff — compare compressed files
|zcmp||[ options] file [ file2]|
|zdiff||[ options] file [ file2]|
DESCRIPTIONzcmp 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):
- z, Z,
Extensions handled by bzip2(1):
Extensions handled by xz(1):
- Directory in which to place temporary files. If unset, /tmp is used.
- Temporary file for zcmp.
- Temporary file for zdiff.
CAVEATSzcmp 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:
- device special files
- filenames indicating the standard input (“-”)
