I'm running Red Hat Linux 4.2, and am wondering where the PATH variable
is initially set for the bash shell. When I type "set" on the command
line, I find out that

PATH=/usr/local/bin:/bin:/usr/bin:/usr/X11R6/bin:/usr/bin/mh:/home/spencer/bin

My ~/.bash_profile has the following line:

PATH=$PATH:$HOME/bin

The /etc/profile has the following line:

PATH="$PATH:/usr/X11R6/bin"

So where do /usr/local/bin, /bin, /usr/bin, and /usr/bin/mh get placed into
the PATH? Is there a file that gets read before /etc/profile? Also,
the placement of /usr/bin/mh seems to indicate that it gets added after
/etc/profile is read and before ~/.bash_profile is read.

Thanks for any help.

Huh? /etc/environment? On what system would this be?

From the login(1) man pages:

Login enters information into the environment (see environ(7)) specify-
ing the user's home directory (HOME), command interpreter (SHELL), search
path (PATH), terminal type (TERM) and user name (both LOGNAME and USER).
^^^^^^

The standard shells, csh(1) and sh(1), do not fork before executing the
login utility.

AIX 3.2 / AIX 4.1

From the login(1) man pages:
Initiates a session The login command initializes the user en-
vironment from the user database, from the command line, and from
the /etc/environment configuration file; changes the current
directory to the user's home directory (normally); and runs the
user's initial program.

SunOS/Solaris, freeBSD, SCO, AIX,
5.5.1/2.5.1 also have /etc/profile then ~/.profile almost all variants do.

I believe that it also executes /etc/profile before executing
~/.profile. However, I am not sure if this happens before or after
sourcing /etc/environment. Of course this assumes that we are not
talking about the c shell. In addition, if the shell is the korn shell,
if ENV= is set then the file named in $ENV is sourced as well.
I do not know how much of this applies to other flavors of unix.

Hi,

The user env. is set by the following way:
1. /etc/login.defs - for shadow passw. login
2. /etc/profile
3. ~/.profile, ~/.bash_profile, etc.

This of cource may vary, depending on which login program you use.
