shebang under linux does not split arguments

linux bash shell ubuntu gnu-coreutils

On Linux, you can't pass more than one argument via the shebang line. All arguments will be passed as a single string to the executable:

#!/bin/foo -a -b -c

will pass one option "-a -b -c" to /bin/foo, plus the contents of the file. Like if you would call:

/bin/foo '-a -b -c' contents-of-file.txt

The behaviour should be the same on most unix derivates nowadays, but it can differ, I haven't tested them all :)

It's hard to find proper documentation for this, the best I could quickly find was this: https://www.in-ulm.de/~mascheck/various/shebang/#splitting

As a workaround you would normally create a shell wrapper:

#!/bin/bashexec kotlin --arg1 --arg2 ... /path/to/kotlin-script

linux bash shell ubuntu gnu-coreutils

Check your coreutils version:

apt-cache policy coreutils

Starting with coreutils 8.30 you will be able to use:

#!/usr/bin/env -S command arg1 arg2 ...

You may want to upgrade your coreutils
