copy flash tftp
This is the command to use to copy the current IOS image to whatever tftp server you are using.
show file systems - shows the various places (directories) on a cisco router where files are stored
cd nvram: - this changes the current directory to the nvram directory. To get back to flash, which is apparently the home directory, just type cd by itself
dir - just like DOS! - shows listing of files in the current directory
pwd - just like Linux! - shows what the present working directory is
show file information flash:c870-advsecurityk9-mz.124-4.T7.bin - this gives some info about the file named c870-advsecurityk9-mz.124-4.T7.bin in the flash: directory
delete slot0:myconfig - this erases the file named myconfig in slot0:
Erasing flash memory
In order to reclaim any space taken up by files in Flash memory, you must erase the entire file system using the erase flash: or erase bootflash: EXEC command. These commands reclaim all of the space in Flash memory, erasing all files, deleted or not, in the process. Once erased, these files cannot be recovered. Before erasing Flash memory, save any files you want to keep in another location (an FTP server, for example). Copy the files back to Flash memory after you have erased the device.
