How can I use the value of an argument as a filename? Example:
The argument for a process is 999. I would like the output of the process to be placed in a file called 999. I have tried using $$1, but that only assigns a unigue number.
thanks

pmt-ehd
pmt-ehd(8) pam_mount pmt-ehd(8)Name
pmt-ehd - create an encrypted disk image
Syntax
pmt-ehd [-DFx] [-c fscipher] [-h hash] [-k fscipher_keybits] [-t fstype] -f container_path -s size_in_mb
Options
Mandatory options that are absent are inquired interactively, and pmt-ehd will exit if stdin is not a terminal.
-D Turn on debugging strings.
-F Force operation that would otherwise ask for interactive confirmation. Multiple -F can be specified to apply more force.
-c cipher
The cipher to be used for the filesystem. This can take any value that cryptsetup(8) recognizes, usually in the form of "cipher-
mode[-extras]". Recommended are aes-cbc-essiv:sha256 (this is the default) or aes-xts-essiv:sha256.
-f path
Store the new disk image at path. If the file already exists, pmt-ehd will prompt before overwriting unless -F is given. If path
refers to a symlink, pmt-ehd will act even more cautious.
-h hash
Message digest/hash used for key derivation in the PBKDF2 stage. The default is sha512.
-i cipher
(This option had been removed in pam_mount/pmt_ehd 2.11.)
-k keybits
The keysize for the cipher specified with -c. Some ciphers support multiple keysizes, AES for example is available with at least the
keysizes 192 and 256. Defaults to 256 (to match aes-cbc-essiv). Note that XTS uses two keys, but drawn from the same key material,
so aes-cbc-256 is equivalent to aes-xts-512, and aes-cbc-128 is to aes-xts-256.
-p path
(This option had been removed in pam_mount/pmt_ehd 2.11.)
-s size
The initial size of the encrypted filesystem, in megabytes. This option is ignored when the filesystem is created on a block device.
-t fstype
Filesystem to use for the encrypted filesystem. Defaults to xfs.
-u user
Give the container and fskey files to user (because the program is usually runs as root, and the files would otherwise retain root
ownership).
-x Do not initialize the container with random bytes. This may impact secrecy.
Description
pmt-ehd can be used to create a new encrypted container, and replaces the previous mkehd script as well as any HOWTOs that explain how to
do it manually. Without any arguments, pmt-ehd will interactively ask for all missing parameters. To create a container with a size of 256
MB, use:
pmt-ehd -f /home/user.cont -s 256
