Usage

onion-address-validate reads an onion address from the standard input and will return an exit code of 0 if the address is valid and a nonzero exit code otherwise. For example:

$ echo "pg6mmjiyjmcrsslvykfwnntlaru7p5svn6y2ymmju6nubxndf4pscryd.onion" | onion-address-validate
$ echo $?                
0
$ echo "qg6mmjiyjmcrsslvykfwnntlaru7p5svn6y2ymmju6nubxndf4pscryd.onion" | onion-address-validate
error: checksum mismatch
$ echo $?
1
