aware of the -Rf flags, that force the recursive removal of an entire directory. Our first solution was to use this tool. The command function, which does the shelling out, runs rm -rf as if we were could have been the end of this talk. But it wasn’t. How many of you think that shelling out to rm -rf was a good solution? How many not? The Problem With the Solution? • Shelling out to a binary can Removeat(directory, path) } v_7b8mqs45lgch7rf49sdm240000gn/T/989178669/eeeeeeee/ooo /var/folders/bq/ } Removeat(directory, path) } v_7b8mqs45lgch7rf49sdm240000gn/T/989178669/eeeeeeee/ /var/folders/bq/
