Method for successfully adding Environment Variables

My method for successfully adding environment variables-general Linux technology-Linux technology and application information. For more information, see the following. To set the PATH of the environment variable in Linux:

There is a. bashrc file in the user's main directory. You can add the PATH settings in this file as follows:

Export PATH = "$ PATH:/your path1/:/your path2 /....."

Note: Each path must be separated.

Log out and restart X (logout ).

This method is indeed correct. I have no problem after the test, but pay attention to the problems I didn't realize at the beginning, because the profile file is actually a program, so the question of where to add is really depressing to me. I wanted to add only one PATH variable. I don't want it to have a program segment for setting the PATH variable, there is also an export later. Finally, I thought about the sentence I added:

PATH = "$ PATH:/usr/local/arm/2.95.3/bin"

It should be added to the end of the PATH string rather than replacing the string, so it has been changed, and the following export is also done, so it is done, the test is successful, no problem.
