My bash script:
#!/bin/bash
cd /tmp
Before running my script:
pwd: /
After running my script:
pwd: /
After runnig my script trough sourcing it:
pwd: /tmp
How I can stay at the path from the script without sourcing it ?

How do I avoid accidental overwriting of a file on bash shell? You can tell bash shell not to delete file data / contents by mistake by setting noclobber variable. It can keep you from accidentally destroying your existing files by redirecting input over an already-existing file.
You can go back to the parent directory of any current directory by using the command cd .. , as the full path of the current working directory is understood by Bash . You can also go back to your home directory (e.g. /users/jpalomino ) at any time using the command cd ~ (the character known as the tilde).
The exit command can be written into a Bash script to manually terminate it at a certain point. An exit code of 0 usually indicates that the script exited without any errors. An exit code of 1 or higher usually indicates that an error was encountered upon exit.
End is the way you "call" the text you are about to insert. Once you are done, you indicate the end of the block with the same word in the very beginning of a new line.
You can't. Changes to the current directory only affect the current process.

Let me elaborate a little bit on this:
When you run the script, bash creates a new process for it, and changes to the current directory only affect that process.
When you source the script, the script is executed directly by the shell you are running, without creating extra processes, so changes to the current directory are visible to your main shell process.
So, as Ignacio pointed out, this can not be done
