You are missing the echo in the else branch.
On top, a function will always have a complete set of parameters of its own, so, in your case, usage will always have zero parameters, regardless of how many parameters your script has gotten. Do input error testing in the body of the script, then call respective error handlers/functions.

ARCHPATH(1)						      General Commands Manual						       ARCHPATH(1)

NAME
archpath - output arch (tla/Bazaar) archive names, with support for branches SYNOPSIS
archpath archpath branch archpath branch--version DESCRIPTION
archpath is intended to be run in an arch (tla or Bazaar) working copy. In its simplest usage, archpath with no parameters outputs the package name (archive/category--branch--version) associated with the working copy. If a parameter is given, it may either be a branch--version, in which case archpath will output a corresponding package name in the current archive and category, or a plain branch name (without '--"), in which case archpath will output a corresponding package name in the current archive and category and with the same version as the current working copy. This is useful for branching. For example, if you're using Bazaar and you want to create a branch for a new feature, you might use a com- mand like this: baz branch $(archpath) $(archpath new-feature) Or if you want to tag your current code onto a 'releases' branch as version 1.0, you might use a command like this: baz branch $(archpath) $(archpath releases--1.0) That's much easier than using 'baz tree-version' to look up the package name and manually modifying the result.
