Restore git submodules from .gitmodules

Question

I have a folder, which was a git repo. It contains some files and .gitmodules file. Now, when I do git init and then git submodule init, the latter

Answer 1

I know its been a while, but I want to share this version that calls git config only once, doesn't requires a script and also handles branches:

git config -f .gitmodules --get-regexp '^submodule\.' | perl -lane'
$conf{$F[0]} = $F[1]}{
@mods = map {s,\.path$,,; $_} grep {/\.path$/} keys(%conf);
sub expand{$i = shift; map {$conf{$i . $_}} qw(.path .url .branch)}
for $i (@mods){
    ($path, $url, $branch) = expand($i);
    print(qq{rm -rf $path});
    print(qq{git submodule add -b $branch $url $path});
}
'

The only side effect is the output of the commands, nothing gets executed, so you can audit before committing to them.

This works with a simple copy and paste at the console, but should be trivial to put in a shell script.

example output:
