The operating system is indispensable in the computer. And the development of Linux is very rapid, there is a trend to catch up with Microsoft. Here introduces the knowledge of Linux, so that you can learn to apply Linux system well. For example, to add the / etc/apache/bin directory to PATH, there are three ways:

1.#PATH=$PATH:/etc/apache/bin

Using this method, it is only valid for the current session, that is, every time you log out or log out of the system, the PATH setting becomes invalid.

2.#vi / etc/profile

Add PATH=$PATH:/etc/apache/bin at the appropriate location (note: = that is, there cannot be any spaces on either side of the equal sign)

This method will not be changed unless you manually force the value of PATH to be changed.

3.#vi / .bash_profile

Modify the PATH line to add / etc/apache/bin

This method works for users.

Note: if you want to change the PATH, you must log in again to take effect. The following methods can simplify the work:

If / etc/profile is modified, the value of the source profile or dot command. / profile,PATH will take effect immediately after editing.

The principle of this method is to execute the / etc/profile shell script again, note that it is not possible to use sh / etc/profile, because the sh is executed in the child shell process, even if the PATH changes will not be reflected in the current environment, but the source is executed in the current shell process, so we can see the PATH change.
