/usr/local/bin
. How can I add /usr/local/bin
to my PATH variable, so that I can run the command without specify the path?In Linux, PATH
environment variable stores a set of directories to search for an executable command when the command is typed by a user. The value of PATH
variable is formatted as a series of colon-separated absolute paths. Each user has a user-specific PATH
environment variable (initialized with system-wide default PATH
variable).
To check the current PATH
environment variable of a user, run the following command as the user:
$ echo $PATH
/usr/lib64/qt-3.3/bin:/bin:/usr/bin:/usr/sbin:/sbin:/home/xmodulo/bin
Alternatively, run:
$ env | grep PATH
PATH=/usr/lib64/qt-3.3/bin:/bin:/usr/bin:/usr/sbin:/sbin:/home/xmodulo/bin
If the command that you type is not found in any of these directories, the shell will throw an error message: "command not found"
If you want to add an additional directory (e.g., /usr/local/bin
) to your PATH
variable, you can follow these instructions.
PATH
Environment Variable for a Particular User OnlyIf you want to temporarily add a new directory (e.g., /usr/local/bin
) to a user's default search path in the current login session, you can simply type the following.
$ PATH=$PATH:/usr/local/bin
Now check if PATH
has been updated:
$ echo $PATH
/usr/lib64/qt-3.3/bin:/bin:/usr/bin:/usr/sbin:/sbin:/home/xmodulo/bin:/usr/local/bin
The updated PATH
will then remain effective in the current login session. The change, however, will be lost in any new terminal session.
(For bash
users) If you want to change PATH
variable permanently, open ~/.bashrc
(or ~/.bash_profile
) with a text editor, and append the following line.
export PATH=$PATH:/usr/local/bin
Then activate the change permanently by running:
$ source ~/.bashrc (or source ~/.bash_profile)
PATH
Environment Variable System-wideIf you want to permanently add /usr/local/bin
to system-wide default PATH
variable, edit /etc/profile
as follows.
$ sudo vi /etc/profile
export PATH=$PATH:/usr/local/bin
Once you re-login, the updated PATH
variable will take effect.
