ASA 5505 - "invalid input detected" when attempting to delete image from flash

esa_fresa — Tue, 12 Mar 2019 07:26:59 GMT

I'm unable to delete an image from flash on 5505. I'm able to question mark after erase but as soon as I add a / to specify the file name it gives me invalid input with the ^ pointing at the F in flash:. Any ideas what's causing this? I've tried entering it from both exec and conf t mode with same issue, and I'm confident that I'm in privilege 15, although show privilege isn't a recognized command either, which further confuses me.

# erase flash:/asa917-k8.bin
^
ERROR: % Invalid input detected at '^' marker.
#

# erase ?

disk0: Filesystem to be erased
flash: Filesystem to be erased
# erase flash:/?
ERROR: % Unrecognized command
# erase flash:?

flash:

delete flash:/asa917-k8.bin

delete flash:/asa917-k8.bin

Well that worked. I'm still

Well that worked. I'm still confused on why show priv wasn't recognized. Or why there's an erase and a delete command with different functionality. Oh well. Thank you!

erase is for wiping the whole

erase is for wiping the whole flash disk, not just a single file. So consider yourself a lucky escape there.
