Where is the PATH variable defined? I mean besides .bash_profile or .bashrc.

/etc/profile

Here is the thing.
I need to remove QTDIR variable and related but I forgot where I put them. What files can contain this kind of variables?

Hi,

/etc/profile is executed whenever the user log in the system.

The system uses .bashrc, .bash_profile, .profile, .cshrc , it depends of
the user shell defined in the /etc/password when the account was created.

You should read "man bash"

When bash is invoked as an interactive login shell, or as a non-inter-
active shell with the --login option, it first reads and executes com-
mands from the file /etc/profile, if that file exists. After reading
that file, it looks for ~/.bash_profile, ~/.bash_login, and ~/.pro-
file, in that order, and reads and executes commands from the first
one that exists and is readable. The --noprofile option may be used
when the shell is started to inhibit this behavior.

When a login shell exits, bash reads and executes commands from the
file ~/.bash_logout, if it exists.

When an interactive shell that is not a login shell is started, bash
reads and executes commands from ~/.bashrc, if that file exists. This
may be inhibited by using the --norc option. The --rcfile file option
will force bash to read and execute commands from file instead of
~/.bashrc.

or "man csh"

A login shell begins by executing commands from the system files
/etc/csh.cshrc and /etc/csh.login. It then executes commands from
files in the user’s home directory: first ~/.tcshrc (+) or, if
~/.tcshrc is not found, ~/.cshrc, then ~/.history (or the value of the
histfile shell variable), then ~/.login, and finally ~/.cshdirs (or
the value of the dirsfile shell variable) (+). The shell may read
/etc/csh.login before instead of after /etc/csh.cshrc, and ~/.login
before instead of after ~/.tcshrc or ~/.cshrc and ~/.history, if so
compiled; see the version shell variable. (+)

Non-login shells read only /etc/csh.cshrc and ~/.tcshrc or ~/.cshrc on
startup.


Good luck,

I'm using bash.
I checked .bash_profile and .bashrc and there is nothing about QTDIR.
I can't find .profile file. I don't have it in my home directory.
But QTDIR is defined somewhere because I can do 'echo $QTDIR' and I get the path.
Now, qt documentation for the 3.3 version says that I should have it in the .profile file. But I can't find it.
