'dlpkg' will download a package to the current working directory or will mirror the source directory structure locally or if a directory argument is supplied will download to that

Note: 'dlpkg' does not resolve dependencies.

--> dlpkg -h

dlpkg [-options] [args]
 
-P  supply a directory to download to. can be combined with -d ie:
    
    dlpkg -d -P somedir
    
-d  downlowads the repository directory structure from the URL basename
    to pkg location. so for repo.com/path/to/src/location/pkg.txz 
    you would get src/location/pkg.txz locally. combined with the -P opt
    you would get somedir/src/location/pkg.txz

-h  show this help

Create a directory to work in cd into it.

mkdir work;
cd work;

I'll use slkn-vm (a SlackBuilder package that provides scripts to run qemu virtual machines) to demonstrate with.

--> dlpkg slkn-vm

Now to see if it downloaded the file.

--> ls
slkn-vm-1.1-noarch-7_Skn.txz

With the -d option...this will download the source directory structure along with the package...

--> dlpkg -d slkn-vm

A recursive listing shows the path to the file...

--> lr
.:
Slackbuilder-noarch-all/

./Slackbuilder-noarch-all:
slackerson/

./Slackbuilder-noarch-all/slackerson:
slkn-vm-1.1-noarch-7_Skn.txz

Similar to wget's -P, dlpkg's -P option lets you determine the path to the download location...

--> dlpkg -P here slkn-vm
