NAME
gzexe —
create auto-decompressing
executables
SYNOPSIS
gzexe |
[-d] file ... |
DESCRIPTION
Thegzexe 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 or
programs it needs to perform on-the-fly decompression:
sh(1),
mktemp(1), rm(1),
echo(1), tail(1),
gzip(1), and
chmod(1).

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.
