System.cmd - No such file or directory

Hello, I am trying to run an lp (That is LP in caps for clarity), and am getting an error:
/usr/bin/lp: No such file or directory

that executable exists on the box because ‘which lp’ returns /usr/bin/lp

Here is how I am running it:

 System.cmd("/usr/bin/lp", [
      "-h",
      "printer:631",
      "-U",
      "printuser",
      "-o",
      "fit-to-page",
      "-d",
      name,
      path
    ])

I have also tried by not providing the full path to lp but also get the same error. Additionally, i’ve tried with :os.cmd and that also shows the same error… Anyone have any ideas?

Does the file exist that are specified via name and path?

Yes: File.exists?("/usr/bin/lp") returns true. Sorry I should have mentioned that.

Im Not asking if lp exists, but if the file you specify as print target via path and name.

Please show the exact error message. Does System.cmd("which", ["lp"]) return the expected path? Are you running inside docker or some other construct?
