Hello, i was trying to add a specific path to the PATH enviroment variable. I read some answers about this, but didnt succeed. Right now, although the file "/etc/profiles" contains the desired path, when i type:
# echo $PATH
i don't see it. i was looking to add it to the files "/etc/profile" and "/etc/bashrc" as well, but didnt find where.
Please help, Oded
~ is your home directory, so ~/.bash_profile is in your home dir and it's created by default when you create a user account.
To add a custom path to the PATH env var for all users, you can edit /etc/profile and/or /etc/bashrc but I think it's better to create a file under /etc/profile.d/ e.g. /etc/profile.d/file.sh (the name doesn't matter but the extension must be .sh), and put this in it:
PATH=$PATH:/path/to/wherever export PATH
Thanks! Even if an answer is covered in more broad terms by another, it can be helpful for people looking for a specific answer to have some overlap.
Ahmad Samir is right for the following reasons: 1. Security. 2. It is cleaner because it promotes modularity. However to activate and test immediately without loging out you can make the settings available to the shell environment by sourcing as follows:
source /etc/profile.d/allusersoath.sh or using sh interpreter sh /etc/profile.d/allusersoath.sh or using bash interpreter bash /etc/profile.d/allusersoath.sh or use . command . /etc/profile.d/allusersoath.sh it will execute the script in the current shell without forking a sub shell. In other words, this executes the commands specified in the scriptfile in the current shell, and prepares the environment for you.

As indicated by /etc/bashrc and /etc/profile, create custom.sh in /etc/profile.d/ by executing
touch /etc/profile.d/custom.sh
and
chmod +x /etc/profile.d/custom.sh
This file is not a sytem file such as /etc/bashrc, but customed (hence the name) to the user such as ~/.bashrc. Enter into this file the following (not my actual file, just a demonstration)
> if shopt -q login_shell; then
> printf '%s %s\n %s\n' 'Loading /etc/profile.d/custom.sh'\
> '(See /etc/bashrc or /etc/profile)...'\
> 'Invoking interactive login shell...'
> if [ "$TERM" = "linux" ]; then
> printf '%b %s%b\n' "\E[32mHi $USER from Virtual Console" `tty` "\E[0m"
> fi
> printf '%s:\n' 'Set following ENV variable(s)'
> printf ' %s\n' '1. SAMPLE_VAR1'
> SAMPLE_VAR1="From file /etc/profile.d/custom.sh, a sample variable."
> else
> printf '%s %s\n %s\n' 'Loading /etc/profile.d/custom.sh'\
> '(See /etc/bashrc or /etc/profile)...'\
> 'Invoking interactive non-login shell...'
> printf '%s:\n' 'Set following ENV variable(s)'
> printf '%s\n' '1. SAMPLE_VAR2'
> SAMPLE_VAR2="From file /etc/profile.d/custom.sh, a sample variable."
> if my_bin=$(echo $PATH | grep "$HOME/bin"); then
> printf '%s\n' "Path to \"${my_bin##*:}\" already set."
> else
> PATH=$PATH:$HOME/bin
> fi
> fi
Into the files
enter, for example,
"# My Section"
"printf '%s\n' 'Loading /etc/bashrc...'"
"# Done My Section"
Now
Caveat: don't put environment variables into ~/.bashrc; use custom.sh.

Do not edit global system files - use
~/.bashrcinstead: https://ask.fedoraproject.org/en/question/35168/cant-login-in-fedora-after-switching-from-openjdk-to-oracle-java/ . The answer to you question is provided at https://ask.fedoraproject.org/en/question/24028/how-to-set-environment-variable-permanet/So, how do i set a permanent change to PATH?
If you want to change the PATH env var for just one user, revert the changes you did in /etc/profile and instead edit ~/.bash_profile.
By default you should find these two lines in ~/.bash_profile:
for example in this case $HOME/bin is added to the PATH env var. Note that you'll need to log out / log in for the changes to take effect in bash sessions (or you can
source ~/.bash_profilemanually until you log out / log in).Thanks for your answer, but i think i don't have this file. Anyway, not in /ect and not in / And, i would like to set the PATH env var to all users.
@Ahmad Samir - looks like you have all the info for a very thorough answer!
