[Bash] Add Executable Files to $PATH with Bash
$PATH
PATH is a global environment variable that represents a list of directories bash looks in for executable files. The executable files for bash commands like grep are all somewhere on your OS’s PATH. We can add our own folders to PATH to make our executables available as a command to bash. In this lesson we’ll learn how to add a new folder to our PATH in .bash_profile and how to symlink an executable file into /usr/local/bin, which is in PATH by default.
Note that in zsh, when modifying your PATH you to provide an absolute path, ~ is not expanded.
You can see the PATH
:
echo $PATH
You can see one executable command where it located:
which ng
Add your executable command to the $PATH:
export PATH="$PATH:~/my-scripts"
Make the script:
mkdir -p my-scripts
echo 'echo hello' > my-scripts/hello
chmod +x my-scripts/hello
source .bash_profile
Then run hello
, you shoul see the output.
Other way
Another way to add an executable to $PATH is by symlinking an executable file into an existing folder that is always in $PATH.
echo 'echo hello2' > my-scripts/hello2
ln -s ~/hello2 /usr/local/bin
