Joe,
I just downloaded version 1.6.5.
A documentation comment and request. Reading the code, there is mention of the 'p' option on line 41 (added in version 1.6) but there is no mention of the 'p' switch/option in the script help (function usage) lines 74-98. This means that if I do a:
cache_dirs -h
I will not see any reference to the 'p' switch.
Considering your comments on lines 129-136, I think it is important that people know about changing cache_pressure and the 'p' switch should be documented.
Please consider updating the usage function to include 'p' switch.
Thanks,
Rick
