It depends of the command. Most basic binaries come from gnu.org.
Whatever your distribution is, Debian repository is a good starting point
to get source files, at this url:
Type the name of the file in the section "search contents" (bin/ls to get
less matches than just ls)
Then you see the file in the package fileutils, and from the package page
you can download the source tarball (not modified by Debian) :

Your executable file must be in your path:
"echo $PATH" to see it
"export PATH=~/bin:$PATH" to insert a new directory at the start of your path
Put this in ~/.bashrc (or similar depending of your shell) to make it permanent.
Usual directories are /usr/local/bin (system-wide) or ~/bin (each user)
