$PATH can have several paths separated by a colon (:). E.g.:

export PATH=/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/sbin:/home/myuser/bin

Set the $PATH environment variable to include the directory where you installed the bin directory with shell scripts and two consecutive export entries as in example.

Example:

export ANT_HOME=/path/to/ant/dir
export PATH=${PATH}:${ANT_HOME}/bin:${JAVA_HOME}/bin

To make them permanent entries update the bash_profile file.

One way to add multiple executables to the $PATH variable is:

export PATH=/path/to/executable1:\
/path/to/executable2:\
/path/to/executable3:\
/path/to/executable4

If a $PATH already exists in .bash_profile, and you want them to take precedence over executables (like java and php), you can do:

export PATH=$PATH:/path/to/executable1:\
/path/to/executable2:\
/path/to/executable3:\
/path/to/executable4

If the path to any executable contains whitespaces, add the part / ... executableX in quotes.

Once you're done making changes in your bash_profile, source the file in a terminal session so that changes are effective immediately:

source .bash_profile
