/usr/bin/lockfile is missing in Beta 4

Originator:Nate.Walck
Number:rdar://21962862 Date Originated:23-Jul-2015 09:47 AM
Status:Closed Resolved:Nope
Product:OS X Product Version:10.11 15A226f
Classification:Other Bug Reproducible:Yes
 
Summary:
The 'lockfile' binary, which normally lives in '/usr/bin' has gone missing in 10.11 Beta 4.

This binary was extremely useful for writing bash scripts that wouldn't stomp on each other while running as a service. Was this binary removed intentionally? If so, can we expect it to stay gone?

 It would be super useful to have this functionality and I am certain it will break scripts for many folks.

Steps to Reproduce:
1. Go to /usr/bin
2. Observe that the lockfile binary is missing

Expected Results:
1. Go to /usr/bin
2. Celebrate and use the lockfile binary

Actual Results:
1. Go to /usr/bin
2. Despair over the missing lockfile binary and consider making your own janky lockfile solution for scripts.

Version:
OS X 10.11 Beta 15A226f

Notes:
There is no known workaround at this time, other than implementing your own lockfile solution from scratch (ewwww)

Configuration:
This is persistent on 10.11 beta 15A226f
