Should I put #! (shebang) in Python scripts, and what form should it take?
Should I put the shebang in my Python scripts? In what form?
shebang
Cannot pass an argument to python with “#!/usr/bin/env python”
I needed to have a directly executable python script, so i started the file with #!/usr/bin/env python. However, I also need unbuffered output, so i tried #!/usr/bin/env python -u, but that fails with python -u: no such file or directory.
Who runs the interpreter for files that are execute-only?
If the current user only has execute (–x) permissions on a file, under which user does the interpreter (specified by #!/path/to/interpreter at the beginning of the file) run?
Separate environment with different /bin/sh
I have a bunch of shell scripts which incorrectly assume /bin/sh to be equivalent to /bin/bash. E.g., they have the #!/bin/sh shebang, but use the source command instead of . (dot).
Choose interpreter after script start e.g. if/else inside hashbang
Is there any way to dynamically choose the interpreter that’s executing a script? I have a script that I’m running on two different systems, and the interpreter I want to use is located in different locations on the two systems. What I end up having to to is change the hashbang line every time I switch over. I would like to do something that is the logical equivalent of this (I realize that this exact construct is impossible):
Run script in a screen
I want to run a bash script in a detached screen. The script calls a program a few times, each of which takes too long to wait. My first thought was to simply open a screen and then call the script, but it appears that I can’t detach (by ctrl-a d) while the script is running. So I did some research and found this instruction to replace the shebang with following:
