How to set PATH only in bash script temporarily?
it's simply not true. If you write a script and change the $PATH variable, the change live only in the script:
vi test.sh
inside the file:
#!/bin/bash
export PATH="$PATH:test"
let's test:
echo $PATH
/usr/lib64/qt-3.3/bin:/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/home/matteo/.local/bin:/home/matteo/bin:./bin:/home/matteo/.local/bin:/home/matteo/bin:./bin
chmod ug+x test
./test
echo $PATH
/usr/lib64/qt-3.3/bin:/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/home/matteo/.local/bin:/home/matteo/bin:./bin:/home/matteo/.local/bin:/home/matteo/bin:./bin
same output. The change is effective only inside the script!
I think you are looking for "source" command (linux).
First write you set Path command (or whatelse) in file, like this loadMyEnvironment.sh
#!/bin/bash
export PATH="$PATH:test"
export MESSAGE="Now i am available on the current shell"
Now,type in the shell,
> source ./loadMyenvironment.sh
Now, in current shell you can check that your envs are loaded.
> echo $MESSAGE
Now i am available on the current shell
hope this helps.
