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.
dir	All	Displays the directory's contents. The /all option shows deleted and undeleted files.
erase	A, B	Erases the entire filesystem.
format	A, C	Formats the filesystem.
fsck	C	Verifies the filesystem's consistency.
mkdir	C	Makes a new subdirectory.
more	All	Displays a file's contents.
pwd	All	Displays the current directory.
rename	C	Renames a file.
rmdir	C	Deletes a directory.
show file descriptors	All	Shows open file descriptors.
show file information	All	Shows file size, location, etc.
show file system	All	Shows available filesystems on the device.
squeeze	A	Makes more room by moving files to the beginning of the flash memory, removing deleted files, and removing files with errors.
tftp-server	All	Sets the device to act as a TFTP server.
undelete	A, B	Recovers any deleted files. Erased files cannot be undeleted.
verify	All	Verifies that a file's checksum is correct.
