Hello, I'm running Ubuntu Linux 5.04.
I just started teaching myself Python today, and have been reading a few things to get started. I came across something in one (namely http://docs.python.org/tut/node4.html#SECTION004220000000000000000) that confused me a little. It says: ------------ On BSD'ish Unix systems, Python scripts can be made directly executable, like shell scripts, by putting the line #! /usr/bin/env python (assuming that the interpreter is on the user's PATH) at the beginning of the script and giving the file an executable mode. The "#!" must be the first two characters of the file. On some platforms, this first line must end with a Unix-style line ending ("\n"), not a Mac OS ("\r") or Windows ("\r\n") line ending. Note that the hash, or pound, character, "#", is used to start a comment in Python. The script can be given a executable mode, or permission, using the chmod command: $ chmod +x myscript.py ----------- So I created a file named helloworld.py, and put in it: #! /usr/bin/env python print "Hello, world!" and then used $ chmod +x helloworld.py to set the permissions. Finally, I went to my terminal and typed $ helloworld.py but I was given the bash: helloworld.py: command not found error. Can someone tell me (1)Am I right in saying that something is directly executable if I can enter the filename in the command line and it runs? (2)Am I setting up the script to be directly executable correctly? and (3)Am I trying to run the directly executable script correctly? Thanks a lot. I hope this post isn't too hard to follow; I know I'm asking a lot. ~~Ted Present -- http://mail.python.org/mailman/listinfo/python-list
