Filesystem commands

Command
Filesystem
Description
cd
All
Changes the working directory.
delete
All
Deletes a file. On Class A filesystems, this command marks the file for deletion; the squeeze command purges deleted files from the filesystem. On Class B filesystems, the files disappear from directory listings (unless you use /all), but there is no way to reclaim the space, short of erasing the entire filesystem. On Class C filesystems, the file is deleted immediately.
