问题
When setting the export path in Unix, example:
export PATH=$PATH: $EC2_HOME/bin
If I quit terminal and open it back up to continue working, I have to go through all the steps again, setting up the paths each time. I'm wondering how I can set the path and have it "stick" so my system knows where to find everything the next time I open terminal without having to do it all over again. Thanks!
回答1:
Open ~/.bashrc. This file is loaded every time you start up a new shell (if you're using Bash, which most people are). If you're using a different shell, the file may have a different name, like ~/.shrc.
Add the line you need to the bottom of the file:
export PATH=$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
回答2:
Add it to your .cshrc file (for csh and tcsh), .profile file (for sh and ksh), or .bash_profile file (for bash)
回答3:
You need to find your profile file and put that line in there. Suppose you use bash, the profile files are .bashrc and .bash_profile, found in ~. These files will vary depending on which shell you use.
回答4:
You have to put those commands into one of the "autostart" files of your shell.
For bash this would be .bashrc in your homedirectory (create it if necessary)
回答5:
add it to your .bashrc or another .bash startup file.
回答6:
... and for ksh edit .profile.
