Also, I sometimes accidentally open a .pyc when I intend to open the corresponding .py. ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor

If Nautilus understands regular expressions, then instead of listing every single .pyc file by name, potentially thousands of them, you just need a single entry: .*pyc to hide *every* .pyc file. Or use .*py[co] for .pyc and .pyo files. If Nautilus *doesn't* understand regular expressions, well, that's just another example of why Gnome is not good enough for serious work.

Is the aforementioned command the best way? [1]. It isn't clear what you mean by "hide them". If you mean that you want to use the ls command to get a directory listing, but just not see the .pyc files, then all you need is: ls *.py which will list the .py files and nothing else. You can remove the .pyc and .pyo files, or move them elsewhere: rm *.py[co] mv *.py[co] some/other/directory/ and let Python recreate them as needed. If you're using a GUI file manager, there may be an option to hide certain files. I know that KDE 3, at least, hides files starting with a leading dot, and backup files ending with ~ so it's quite likely that there's a way to hide .pyc and .pyo files. Check the documentation for your GUI file manager. The command you give: ls *.py[co] >> .hidden doesn't hide anything. It lists the .pyc and .pyo files, but rather than printing to the terminal, it appends them to a file called .hidden in the current directory. Ah, wait, I see! Nautilus uses the .hidden file to suppress the display of those files. I wonder whether putting a single line: .*py[co] inside .hidden will work?

[Tutor] ls *.py[co] >> .hidden
Hi, I would like to hide .pyc and .pyo files because they are visually distracting. Is the aforementioned command the best way? [1]. I know Python 3 uses __pycache__ (much better!), but I also need Python 2. And not writing bytecode files altogether using what's-that-environment-var-called-again is not an option for me. I use Debian Linux (Jessie, since today, yaaayy!)
