Bash glob pattern behaviour different between terminal and shell script

Question

I have a glob pattern {,**/}*.* for recursing through all files in current directory plus children. In the terminal if I run echo {,**/}*.* it outputs all of the files in the current directory plus the nested directories. When I run a shell script which contains this line it only does one directory deep.

I understand that terminal has different behaviour than the shell: adding shopt -s extglob made no difference.

#!/bin/bash

shopt -s extglob
echo {,**/}*.*

I am on MacOSX with Bash 4 terminal and shopt -s globstar enabled.

Answer 1

Thanks @Aserre and @anubhava, it was indeed the combination of bash path and making sure globstar was enabled (for MacOSX). Full script is:

#!/usr/local/bin/bash

shopt -s globstar

echo {,**/}*.*

And yes ./** would suffice but that wasn't my problem :)

Answer 2

{,**/}*.* will not give you all files in current directory plus children. Instead it would give you results of the format

directory/file.ext

You might have used ./** instead

If you globstar, ** will expand to everything in the folder. ie do

shopt -s globstar
echo ./** # this would suffice

Apart from that, borrowing [ this ] comment, you need to use a shell version that supports globstar. This is evident from you getting

shopt: globstar: invalid shell option name

Then,

#!/bin/bash -> #!/usr/local/bin/bash

should do the job
