Accessing custom bash script from SBCL

votes

I've seen this question but it doesn't seem to apply here.

Using SBCL, this works fine:

(run-program "/bin/ls" () :output *standard-output*)

So does this:

(run-program "/Applications/Safari.app/Contents/MacOS/Safari" ())

It launches a Safari window.

I can create a bash script in my bin directory that just has this in it:

/Applications/Safari.app/Contents/MacOS/Safari

When I run this bash script from the Terminal, Safari opens.

But I cannot run this script from inside SBCL:

(run-program "/Users/myhome/bin/safariscript" ())

REPL reports:

Couldn't execute "/Users/myhome/bin/safariscript": Exec format error
[Condition of type SIMPLE-ERROR]

The script certainly works fine on its own. I've searched ad nauseum for the meaning of this error without any help that would apply to a lisp environment, so I wonder if there is a broader issue at play here?

Shell scripts need a shell-bang line in it in order to be run via execve or anything that uses it, such as run-program. So you should use this as your file's content:

#!/bin/sh
exec /Applications/Safari.app/Contents/MacOS/Safari
