Re: having trouble with virtualenvwrapper - need to run 'source ~/.profile' every time.

What I mean by "I don't know about sourceing virtualenvwrapper.sh" is that I don't know, and don't have the inclination to research, whether, having sourced the file in a shell, you should avoid sourcing it again in a sub-shell.

What I mean by guard variables is that you could, at the end of your .bashrc, export a variable that is unlikely to clash with the variables of other systems, e.g.;

    export BASHRC_HAS_ALREADY_BEEN RUN

And earlier in the file test the variable to guard against redoing the things that should not be redone.

    if [ "$BASHRC_HAS_ALREADY_BEEN RUN" -ne "1" ]; then
       # Put stuff that shouldn't be done twice here
    fi

That's the one, thank you so much! I saw in the comments of .profile that it would not be read if there was a .bashrc file present, so my next step was creating that file and putting those lines in it, but I'm very afraid of pooching my install. Noob, like I said. :>

I have Aspergers, so I'm not clear on what you meant by "I don't know about sourceing virtualenvwrapper.sh.  (Guard variables are your friend.)" - I'm assuming, though, that you're referring to a security concern in this line, presumably based on the idea that someone could access virtualenvwrapper.sh and put malicious code in there.

If I've assessed your comment correctly, is there a good, basic tutorial on {guard variables}, as well as the larger schema into which they fit? Preferably one that *does* assume intelligence, but does *not* assume a lot of existing knowledge on the part of the user?


Whatever the case, thank you again for the new knowledge about .profile and .bashrc. :>

The file you want (assuming that your shell is bash) is .bashrc because it is run every time a bash shell is started, even if it is not a login shell.

Note, however, that settings that shouldn't be done multiple times, such as appending ":$HOME/bin" to the PATH, should be protected with an if so they only happen once, no matter how many sub-shells you start (such as by running something in parentheses), so that PATH doesn't grow without bound.  The WORKON_HOME and PROJECT_HOME settings don't suffer from this problem because it doesn't hurt to set them again to the same value.  I don't know about sourceing virtualenvwrapper.sh.  (Guard variables are your friend.)

For some of this stuff it may also be possible to set the environment of the X session, making it available in the environment of shells that are started by the window manager, but you'll have to do your own research on that.

Does gnome-terminal make sense to you in this context? I popped up "edit" on the terminal launcher and that's in the Application field. I would, theoretically, add whatever option for gnome-terminal specifies it as a login shell?

Testing this, I added --login to the field, per this page, but it didn't ask for a login, nor did it run .profile.

Not sure if I'm barking up the proper tree here, natch.

...every time I open a terminal, that is. As I understand it, .profile is the file to edit in Linux Mint, and it does exist, with some basic code in it, in my home dir. So, per this tutorial, I added the following to .profile:
Your terminal is being opened without specifying it as a "login shell". Not sure which terminal program you are using so you will need to check on options; for xterm it is the -ls option.
