How do you use this?

How do you use this?

Call it like this:

./coderesign.sh source "iPhone Distribution: Name" -p "path/to/profile" [-d "display name"] [-e entitlements] [-k keychain] [-b "BundleIdentifier"] outputIpa

Basically, you will pass the original .ipa (source) and an cert identify for which you must have the private key. The -p argument is useful to specify a new or different provisioning file and the other arguments allow you to rename and/or change the bundle id. It's been a few years since I last used it, i don't remember using the -k or -e arguments often.

Good luck!
