`packelf` was inspired by [the idea of Klaus D](https://askubuntu.com/a/546305). It is used to pack a ELF program and its dependent libraries into a single executable file.
## Usage (packelf):
## Usage packelf:
```
Usage: ./packelf.sh <ELF_SRC_PATH> <DST_PATH> [ADDITIONAL_LIBS]
```
First, pack a ELF program. For example, you can pack `ls` like this:
Example:
```
# ./packelf.sh /bin/ls /root/ls
tar: Removing leading `/' from member names
'/bin/ls' was packed to '/root/ls'
Just run '/root/ls ARGS...' to execute the command.
Or run 'PACKELF_UNPACK_DIR=xxx /root/ls' to unpack it only.
# ./packelf.sh /usr/bin/mpv mpv-x86_64.AppRun
```
You can execute the packed program directly:
Note: Every time the packed program is executed, an internal unpacking operation is performed automatically, which results in a slower startup of the program.
```
# /root/ls -lh /root/ls
-rwxr-xr-x 1 root root 1.3M May 21 08:35 /root/ls
```
## Extract without running:
However, every time the packed program is executed, an internal unpacking operation is performed automatically, which results in a slower startup of the program.
You can extract the files of a created package without executing it with the following command:
## USAGE EXTRA TOOLS:
```
# ./<package> --packelf-extract
```
## Usage Extra Tools:
```
Usage: ./packelf-copylibs.sh <ELF_SRC_PATH> <PATH_TO_COPY_LIBRARIES>
