gzexe - create auto-decompressing executables
gzexe [-d] file ...
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 or programs it needs to perform on-thefly decompression:
sh(1), mktemp(1), rm(1), echo(1), tail(1), gzip(1),
and chmod(1).
gzip(1)
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.
