问题 The last time I searched for it I concluded it's not possible, or at least not portable, so I gave up and forgot. However, in a comment to this answer I posted, I was suggested to check env's man page, which contains the following -S, --split-string=S process and split S into separate arguments; used to pass multiple arguments on shebang lines Searching for "multiple parameters" shebang only find 3 results, and none of those mentions this option. What is state of this topic at the moment in

问题 I have several PowerShell scripts that I'd like to invoke directly as a command from a Bash shell in Cygwin. For example, if I write a script with the filename Write-Foo.ps1 , I'd like to execute it as a command from any working directory: $ Write-Foo.ps1 arg1 arg2 ... To do this, I add the script to my PATH, make it executable, and include the following interpreter shebang/hashbang at the beginning of the file: #!/usr/bin/env powershell Write-Host 'Foo' ... It's a common (ab)use of the env

问题 I want to place my Python script into directory listed in PATH and call that script just by typing its name from any location in cygwin on Windows. I'm using shebang #!/usr/bin/env python that works perfect on Linux machine. Nevertheless by calling the following line from windows cygwin I get an error: $ my_script.py some arguments C:\app\Python36\python.exe: can't open file '/cygdrive/d/11_scripts/my_script.py': [Errno 2] No such file or directory Problem is caused by the fact that cygwin

问题 I'm trying to run a Python script from the command line as a command on Windows -- so no usage of "Python" or ".py". If my script is named "testing.py", I am attempting to make this name into a command and call "testing" from the command line. Going through the docs it seems I need to use this shebang #!/usr/bin/env python as long as I have Python in my PATH. https://docs.python.org/3/using/windows.html#shebang-lines I also have the script folder in my PATH, so something like "testing.py" is

问题 Let's say you have 2 conda environments: py3_env and py3_clone_env If you have a script.py with the following structure: #![shebang] import sys def main(): print("hello world", file=sys.stdout) if __name__ == "__main__": main() Is it possible to have the shebang be a variable that is determined from the current conda environment? For example: From py3_env environment: #!~/anaconda/envs/py3_env/bin/python and from py3_clone_env environment: #!~/anaconda/envs/py3_clone_env/bin/python 回答1: I

问题 I'm having a little issue with adding shebang #! with my php script on RedHat linux. I have a small piece of test code with shebang added (I've tried different variations as well), but I get the following error message everytime I try to run the script. Error msg: -bash: script.php: command not found Test script: #!/bin/env php <?php echo "test"; ?> Shebang #! variations: #!/usr/bin/php #!/usr/bin/env php 回答1: It should (for most systems) be #!/usr/bin/env php , but your error isn't related

问题 I'm writing a (somewhat) modular application in Python 3 and I'd like to run arbitrary programs from it, said program being specified at runtime and not necessarily a python script. So I use for example, subprocess.call([spam, "-i", eggs, "-o", ham]) If spam is a python script, with shebang to python3 and executable rights, I get OSError: [Errno 8] Exec format error if I subprocess.call(["python3", spam, "-i", eggs, "-o", ham]) it works fine. Do you know why? How can I run spam without
