GZEXE(1) - General Commands Manual
NAME #
gzexe - create auto-decompressing executables
SYNOPSIS #
gzexe [-d] file …
DESCRIPTION #
The gzexe utility uses gzip(1) to compress executables, producing executables that decompress on-the-fly when executed. This saves disk space, at the cost of slower execution times. The original executables are saved by copying each of them to a file with the same name with a ‘~’ suffix appended. After verifying that the compressed executables work as expected, the backup files can be removed.
The options are as follows:
-d
Decompress executables previously compressed by gzexe.
The gzexe program refuses to compress non-regular or non-executable files, files with a setuid or setgid bit set, files that are already compressed using gzexe, files in /bin or /sbin, or programs it needs to perform on-the-fly decompression: sh(1), basename(1), mktemp(1), rm(1), echo(1), tail(1), gzip(1), and chmod(1).
SEE ALSO #
CAVEATS #
The gzexe utility replaces files by overwriting them with the generated compressed executable. To be able to do this, it is required that the original files are writable.
