Question for those who know a lot about bash scripts

Question

bash

It is required from the bash script to change the value of the variables: PATH and others. Everything seems to work, but it doesn't.

#!/bin/bash

export PATHMY="text"
export PATH="$PATH:/home/myname/test"

I'm doing

echo $PATHMY

Empty, no other variables changed either.

I added the same code to .profile, I log in with a new one and the variables are in place.

How to get changes without logging out?

Ubuntu 11.04 x32

UPD: Perhaps there is a solution in perl or something else - it will not be bad either.

Answer 1

Run the script like this:

 . ./script.sh

Answer 2

In the file ~/.bashrc
Add lines:

PATHMY="text"
PATH="$PATH:/home/myname/test"

Each new bash session will use these variables, declare globally - too, but in /etc/bash.bashrc
In the current session, type these commands in the console or remove export from the script.

Answer 3

1. Through export, variables are changed only within the framework of this session.
2. Therefore, you need to register in .profile or bash.rc.

Answer 4

bash -l

Answer 5

:~$ sourcescript.sh

Answer 6

but frisky is not so necessary?

PATHMY="text"
export $PATHMY

Answer 7

Describe the normal task before you, please. then you can think about how to solve the problem

Answer 8

Do not produce unnecessary entities, declare the variable in the script itself:
PATHMY="text"
PATH="$PATHMY:/home/myname/test"
