How do you return to a sourced bash script?
Is it important that you can change environment variables? Since otherwise you can just execute the script by executing it without source:
someneatscriptthatendsprematurely.sh
You need the return
statement:
return [n]
Causes a function to exit with the return value specified by
n
. Ifn
is omitted, the return status is that of the last command executed in the function body. If used outside a function, but during execution of a script by the.
(source) command, it causes the shell to stop executing that script and return eithern
or the exit status of the last command executed within the script as the exit status of the script. If used outside a function and not during execution of a script by.
, the return status is false. Any command associated with the RETURN trap is executed before execution resumes after the function or script.
You can see this in action with the following two scripts:
script1.sh:
. script2.sh
echo hello again
script2.sh:
echo hello
return
echo goodbye
When you run script1.sh
, you see:
hello
hello again
