create auto-decompressing executables
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:
- Decompress executables previously compressed by
program refuses to compress
non-regular or non-executable files, files with a setuid or setgid bit set,
files that are already compressed using
, files in
, or programs it needs to perform
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.
