Kirkville - Why Use the Command Line in Mac OS X?: "I appreciate your reasons and would like to add one. After I execute a series
of commands that, taken together, define a task, I add the following:

history > cmds.yyyymmdd

where the yyyymmdd part is the current date. When I want to repeat a
cumbersome task, I execute the command

find ~/ -name 'cmds.*'

to retrieve a list of such files. Usually, the directory and date tell me what
task I was doing, so I can tell at once which cmds.* file will refresh my
memory about how to do a similar task.
