How to pipe command

Hi All,


I want to create a command that executes a text editor with the most recent file in the current current directory.

So a good start to achieve this is :

ls -lrt | cut -c55- | tail -1

which provides the name of the most recent file in a directory

The problem is to pipe the result of this command with the text editor command (suppose dtpad).

So my question is : does it exist a way to make something like

ls -lrt | cut -c55- | tail -1 | dtpad XXXX

where XXXX is a variable or a command to force the dtpad command to take as parameter the result of the pipe


Thanks by advance,
Nicolas.

GSHSEC(8)						    BSD System Manager's Manual 						 GSHSEC(8)

NAME
gshsec -- control utility for shared secret devices SYNOPSIS
gshsec label [-hv] name prov prov ... gshsec stop [-fv] name ... gshsec clear [-v] prov ... gshsec dump prov ... gshsec list gshsec status gshsec load gshsec unload DESCRIPTION
The gshsec utility is used for setting up a device which contains a shared secret. The secret is shared between the given providers. To collect the secret, all providers are needed. If one of the components is missing, there is no way to get any useful data from the rest of them. The first argument to gshsec indicates an action to be performed: label Set up a shared secret device from the given components with the specified name. Metadata are stored in the last sector of every component. stop Turn off an existing shared secret device by its name. This command does not touch on-disk metadata! clear Clear metadata on the given providers. dump Dump metadata stored on the given providers. list See geom(8). status See geom(8). load See geom(8). unload See geom(8). Additional options: -f Force the removal of the specified shared secret device. -h Hardcode providers' names in metadata. -v Be more verbose. EXIT STATUS
Exit status is 0 on success, and 1 if the command fails. EXAMPLES
The following example shows how to create a shared secret device. The secret will be split between a slice on a local disk and a USB Pen drive. gshsec label -v secret /dev/ada0s1 /dev/da0 newfs /dev/shsec/secret From now on, when the USB Pen drive is inserted, it will be automatically detected and connected, making the secret available via the /dev/shsec/secret device. SEE ALSO
geom(4), gbde(8), geom(8), newfs(8) HISTORY
The gshsec utility appeared in FreeBSD 5.4. AUTHORS
