List all executables called by a shell script. Take this tool as a package maintainer's knife to check if all needed 3rd binaries are referenced

usage: shellexeclist [-h] [--forceshell FORCESHELL] files [files ...]

a tool to list executables called by a shell script

positional arguments:
  files                 Files to analyze

optional arguments:
  -h, --help            show this help message and exit
  --forceshell FORCESHELL
                        Force to interpret as shell x

By default the used shell is guessed by the shebang, to override that decision pass --forceshell=<the shell of your choice> to CLI.

• bash
• sh (POSIX shell)
• ksh
• zsh

if a not supported shell is found interpretation will fall back to POSIX shell

shellexeclist testfiles/K01speech-dispatcher

returns

[
dirname
echo
exit
install
ln
log_daemon_msg
log_end_msg
set
sh
sleep
start-stop-daemon
test

meaning that this particular script calls all of the mentioned executables in some way

There's is no way to tell if a script is gracefully handling missing executables - this process still requires manual inspection of the sources
