A little time ago, I found out, that I can create custom commandterminals with expanding the PATH-variable. Unfortunately, it gets always resettet, when I close the terminal and opens it again.
Do you know how to fix this problem?
Because when I want to start a few scripts with terminalcommands, I don't want to expand the PATH-variable everytime before ...
I understand you have some executables in one of your home folders, e.g., in ~/bin and you want to be able to execute them without always typing the full path ~/bin/my_cool_executable.
You already observed that entering PATH=~/bin:$PATH in your terminal made things work... but only until you close the terminal. When you open a new one, your former PATH variable gets reset to its original value. By the way, I guess you know how to, at any time, check the value of the PATH variable: like so:
echo "$PATH"
How to make your change permanent so that your PATH will still be the same when you reopen a new terminal? It's very easy, you just need to edit your .bashrc file. Let's use the gedit editor: In a terminal, type this:
gedit ~/.bashrc
This opens up the gedit editor. Scroll to the end of the file and add this:
# Added by me on 2013/06/24
PATH=~/bin:$PATH
export PATH
and save the file and quit gedit. Then close your terminal and open a new one. Now your PATH variable should have ~/bin in front of it so that your commands in ~/bin will be accessible without typing their full path. And you know how to check that: echo "$PATH".
Enjoy!
Warning. It is considered bad practice and a security vulnerability to put . in your PATH variable.
/usr/local/bin instead of fiddling with the PATH variable... or in /usr/local/sbin if they must only be accessed by root.

.bashrc? – gniourf_gniourf Jun 24 '13 at 16:47.bashrcfile like so:gedit ~/.bashrcand put whatever you want in there (at the bottom of the file is better), e.g.,PATH="~/my/cool/path/:$PATH"and export this variable: after the line you just entered, putexport PATHthen save the file, then close your terminal and reopen it and now your executables in~/my/cool/pathwill be found. – gniourf_gniourf Jun 24 '13 at 17:00:)– gniourf_gniourf Jun 24 '13 at 17:10
