As @Olivier Dulac noted in the comment, this is valid only when the script is in the current directory. Otherwise something like /path/to/the/script/my_shell_script.sh or ../../other/dir/my_shell_script.sh must be used. And if the script is in the directory listed in the PATH, then just my_shell_script.sh will suffice. | |
| Nov 10, 2021 at 21:14 | comment | added | The Quark | "Note that if you invoke a script by specifying the interpreter on the command line, as is done in both cases given in the question, exec() will execute the interpreter specified on the command line, it won't even look at the script." This explains why running ./myscript.sh results in a process named "myscript.sh" whereas running bash myscript.sh (or having #! /usr/bin/env bash in the shebang line) results in a "bash" process. Thanks! | |

| Dec 12, 2016 at 3:02 | comment | added | Thomas Nyman | @AlexanderMills I would imagine child_process.{exec(),execFile(),spawn()} all would be implemented using the C exec() (through process). | |
| Dec 11, 2016 at 19:51 | comment | added | Alexander Mills | Huh, yeah I am indeede familiar with the Java API you just mentioned, I wonder if there is a way to invoke the lower level exec() call from Node.js somehow | |
| Dec 11, 2016 at 16:02 | comment | added | Thomas Nyman | @AlexanderMills The exec() referred to in this answer is a system call, the command exec is a shell builtin, which is why you cannot invoke an exec program from Node.js or Java. However, any shell command invoked by e.g. Runtime.exec() in Java is eventually processed by the exec() system call. | |
| Dec 9, 2016 at 20:26 | comment | added | Alexander Mills | thanks Thomas for this answer. Pretend we launch the script as a child process from Node.js or Java or whatever. Can we launch an "exec" process, and then exec will run the shell script? I ask beause I am looking for answers to this question: stackoverflow.com/questions/41067872/… | |
