I need to know if Bash has some solution for my case. I need after some conditions to do a "double return". I mean, to perform a return of a function and also return the parent function to skip the rest of the code of that parent function.
I know that I can do a conditional using function return values to achieve this. But I'd like to know if in Bash exist something like "break 2" for functions. I don't want if possible to modify the code of the parent function because as you can imagine, in my real script there are dozens of functions and I don't want to modify all of them.
Example:
#!/bin/bash
function sublevelone() {
echo "sublevelone"
# Return 2, or break 2 or something :D
}
function main() {
sublevelone
echo "This is the part of the code to being avoid executed"
}
main
This is kinda whacky but if you use parentheses to define levelone
, it will execute the function in a subshell and then you can exit out of that shell from an inner function. That said, I think it's more appropriate to use return
to send back value that you check for in the parent function.
#!/bin/bash
function leveltwo() {
echo "two"
exit
}
function levelone() (
echo "one"
leveltwo
echo "three"
)
levelone
echo "four"
Will print:
one
two
four
