A shell function for quickly opening Xcode project files.

xcopen.sh

#!/bin/sh

# Usage:
#     xcopen [projfile|dirname]
#
# The argument is optional. If an argument is specified and its extension
# is 'xcodeproj', it is treated as a project file. Otherwise, it is treated
# as the directory name. If no argument is specified, the directory name is
# set to '.' (the current working directory). If a project file is specified,
# it is opened. Otherwise, the first project file in the specified directory
# is opened.
#
# Note: the Xcode.app used to open the project file is determined via a call
# to xcode-select(1).
#
# Examples:
#    xcopen ~/Documents/Project/Project.xcodeproj
#    xcopen ~/Documents/Project
#    xcopen
