When setting the export path in Unix, example:
export PATH=$PATH: $EC2_HOME/bin
If I quit terminal and open it back up to continue working, I have to go through all the steps again, setting up the paths each time. I'm wondering how I can set the path and have it "stick" so my system knows where to find everything the next time I open terminal without having to do it all over again. Thanks!
Firstly, we use the dirname command to find the directory in which a file is located. Then we change the directory using the cd command. Next, we print the current working directory using the pwd command. Here, we have applied the -P option to show the physical location instead of the symbolic link.
The export command sets and/or exports variables to the environment. It is equivalent to typeset –x, except when used within functions. Here, the PATH variable is set and exported: $ export PATH=$PATH:/usr/5bin. Multiple variables can be given to the export command.
To modify your path In all cases, replace /dir/path with the directory you want the shell to search. Note: Earlier entries in the path take precedence over later ones. If you want the directories you add to your path to take precedence, in the examples above, replace $PATH\:/dir/path with /dir/path:$PATH .
Open ~/.bashrc.
This file is loaded every time you start up a new shell (if you're using Bash, which most people are). If you're using a different shell, the file may have a different name, like ~/.shrc
.
Add the line you need to the bottom of the file:
export PATH=$PATH:$EC2_HOME/bi
Other info rolled up from elsewhere in the thread:
There are multiple places to put this, depending on your shell and your needs. All of these files are in your home directory:
For Bash:
.bashrc (executed when you shart a shell)
OR
.bash_profile (executed when you log in)
For csh and tcsh:
.cshrc
For sh and ksh:
.profile
Add it to your .cshrc file (for csh and tcsh), .profile file (for sh and ksh), or .bash_profile file (for bash)
