Not a problem.

Most of these commands can be found by running pkgtool and selecting
the "SETUP" option. Additionally these can be found individually in
the /var/log/setup/ directory.

"setup" is not included in a Slackware install. It is only present in
the RAM disk used by the installer. It's not easy to find. Basically,
the installer loads a compressed ext2 filesystem into a small amount of
your system's RAM as an initrd (initial ram disk), so you'll have to
copy that, uncompress it, and mount it.
mount /mnt/cdrom
cd /mnt/cdrom/isolinux/
cp initrd.img /tmp/initrd.img.gz
cd /tmp
gunzip initrd.img.gz
mkdir /mnt/loopback
mount -t ext2 /tmp/initrd.img /mnt/loopback -o loop
You can now find setup somewhere under /mnt/loopback. setup is just a
shell script, so use your favorite text editor to read it. No need to
hunt down source code.

man find
There are a _lot_ of options to find to find files by name, wildcard,
timestamp, permissions, etc. Only time will breed familiarity with the
wonderful find utility, but many websites offer the basics.

I don't really understand the question. Could you please rephrase it?

I'm not sure I'm following you. In DOS, batch files are simple scripts
you can create to do certain things. In Linux, we have something very
similar, though IMHO much more powerful in shell scripts. There are
many different shells: bash, bourne, ash, csh, tcsh, zsh, etc. and each
has its own rules for writing scripts. There is no single "script
language".
As for other programs, there are some built-in programs to the kernel,
but not many. Most everything is an "external" program if I understand
your terminology correctly.
