1. What language is that? I want to read up on it.
Shell scripting -- Bourne shell specifically. Any UNIX has some sort of Bourne shell or other. You may have heard of BASH, KSH, and POSIX shells -- these are all Bourne shells. BASH and KSH have useful extensions on the generic Bourne shell, while the POSIX version is fairly 'pure'. Pure POSIX shell code generally ought to run fine in all three.
When you login to a UNIX system with PUTTY or something, or open a terminal on a UNIX desktop, and see a prompt like user@host #, you're probably typing into a Bourne shell. It can take commands line-by-line as you type them in. It's also an entire programming language, though rather purpose-specific. The one thing it's really good at is running and organizing other commands -- i.e. what you're wanting to do here

2. What would be the general form of any unix command?
I'm afraid this question is so vague it's difficult to answer.

3. What would the unix command to run this with the arguments look like?
[edit] Oh, I think I see what you mean.
Code:
# This only needs to be done once, ever. It sets the file executable, so it can be run.
chmod +x ./myscript.sh
# The arguments don't need to be in any order, except that cfgname must be straight after -cfg, etc.
./myscript.sh -cfg cfgname -dir dir -run 3 -mask -root

does this look right?
Code:
#!/bin/sh
OPT=0
OP=0
while [ "$#" -gt 0 ]
do
case "$1" in
-cfg) cfg_file=$2; shift ;;
-dir) file_name=$2; shift ;;
-run) run_num=$2; shift ;;
-mask) OPT=1 ;;
-root) OP=1 ;;
*) break ;;
esac
shift
done
if [ -z "$cfg_file" ]
then
echo "No config file given" >&2
exit 1
fi
if [ -z "$file_name" ]
then
echo "No file name given" >&2
exit 1
fi
if [ -z "$run_num" ]
then
echo "No run number given" >&2
exit 1
fi
if [ "$OPT" -eq 1 ]
then
../bin/takeData -l -dir $file_name -trimVcal 60 -mask
cd ../convert_to_tree/
cp $file_name/phCalibrationFitTan_C0.dat $file_name/phCalibrationFit60_C0.dat
cp $file_name/phCalibrationFit60_C0.dat ~/log/bt0500$run_num
cp ../convert_to_tree/config.dat_original ~/log/bt0500$run_num
./convert_to_tree -l -r $run_num
./pulseHeightMain $run_num
fi
if [ "$OP" -eq 1 ]
then
cd ~/log/bt05r00$run_num
root -l
else
../bin/takeData -l -dir $file_name -trimVcal 60
cd ../convert_to_tree/
./Analyze.py --dir $file_name --cfg $cfg_file $run_num

then
cd ~/log/bt0500$run_num
root -l
fi
fi
Mostly correct but you're missing a 'fi' here and there. You're also missing the special #!/bin/sh first line which tells UNIX which shell to run this code with. It's possible your system uses /usr/bin/sh instead of /bin/sh, change as appropriate. I've highlighted fixes in red.

I added another option to run the change directory and run root -l and I want to add a -h help option and print some stuff. I'm assuming I'd ad a -h) *something* ;;
Yep. It doesn't have to all be on one line, either. command1 ; command2 ; command3 is equivalent to
Code:
command1
command2
command3
;; on the other hand, is purely a case thing, you don't find it in other kinds of statements.
So, you can do
Code:
case "$something" in
-h)
something
something else
yet more commands
exit # to quit immediately, so it doesn't try to run commands below
;;
esac
'option' can even be a glob, i.e. if you wanted to match all strings beginning with 'opt', you could do opt*)
