I have a Bookworm 64 bit lite Pi
I have a python3 script at /opt/wibble/foobar that works, and runs fine if I do 'cd /opt/wibble' and then 'python3 ./foobar' or './foobar'. Note that the script is owned by dsf:dsf, though I am ian:ian:However, if I copy the script to a little further down the tree, it no longer works:same script, same ownership, same permissions. It does still work with 'python3 foobar', and if I run python interactively it can read and execute the file:What causes this, and how do I fix it?
I've checked each directory down the path, and all have at least r-x for for all u g & o permissions.The script is nothing special:
