losetup: invalid option -- 'l'
Usage:
losetup loop_device give info
losetup -a | --all list all used
losetup -d | --detach <loopdev> [<loopdev> ...] delete
losetup -f | --find find unused
losetup -c | --set-capacity <loopdev> resize
losetup -j | --associated <file> [-o <num>] list all associated with <file>
losetup [ options ] {-f|--find|loopdev} <file> setup
Options:
...
-p | --pass-fd <num> read passphrase from file descriptor <num>
-r | --read-only setup read-only loop device
--show print device name (with -f <file>)
-N | --nohashpass Do not hash the given password (Debian hashes)
-k | --keybits <num> specify number of bits in the hashed key given
to the cipher. Some ciphers support several key
sizes and might be more efficient with a smaller
key size. Key sizes < 128 are generally not
recommended
-v | --verbose verbose mode
