Example gets all branches and tags:
\$ $0 -g git@github.com:hfossli/drmobile-integration.git -o ~/Desktop/drmobile-integration/branches/{{name}}/ -t -b
Flags:
-g Git repo
E.g. git@github.com:hfossli/drmobile-integration.git
-t Tags
-b Branches
-o Path to folder with format (string)
Possible variables:
- {{name}} (name of tag or branch)
- {{type}} ('tag' | 'branch')
E.g. ./path/{{name}}/ will produce ./path/develop/
-h Takes no arguments
Help - detailed guide
-d Takes no arguments
Dry-run (no actual writing)

mktemp will not work on some distros:

mktemp [OPTION]... [TEMPLATE]

Create a temporary file or directory, safely, and print its name.
TEMPLATE must contain at least 3 consecutive `X's in last component.
If TEMPLATE is not specified, use tmp.XXXXXXXXXX, and --tmpdir is implied.

Fixed that, and it worked! Thanks.
