prog2: I understand that there are three parameters that need to be passed($1, $2p, $3), but I don't know what they are. I assume one is a file name and another is a command, but I am not sure what the third is.

That's a start.
Then you need to know how the sed command works: after the options (here: -n) the next word is the sed code. Usually one puts quotes around it, to make it better visible (and allow spaces in it). The next word(s) is(are) input files.
Compare this information with "man sed"; it starts with a short invocation description.
You need to read more in order to understand the given sed command, and what parameters make sense.

./prog2 1,4d Zidane

These are two arguments! Parameter $1 will become 1,4d

The eqivalent of set -x in sh-derived shells is set echo in csh-derived shells. All shells take a -x option:

Code:

sh -x shscript
csh -x cshscript

Where did my programs go?

I notice that (Mandrake) Linux and Windows do not seem to operate alike in terms of installing third party software. Windows, on one hand, creates icons and adds items to the Start Menu, with the help of the InstallShield--or equivalent, of course, but Linux, on the other hand, seems to care...

fixnt(1)							      Debian								  fixnt(1)

NAME

       fixnt - Filter for the Windows NT postscript printer driver.

SYNOPSIS

       fixnt < BADFILE.ps > GOODFILE.ps

DESCRIPTION

       The  Windows  NT  postscript  driver has a tendency to make broken postscript files, that are incompatible with psutils.  fixnt is a filter
       that fixes these problems, allowing the use of psnup(1).

       The filter takes the broken postscript file on stdin, and outputs a fixed postscript file on stdout.  It has no other form  for	invocation
       and takes no options on the command-line.

OPTIONS

       fixnt  takes no options.

BUGS

       fixnt does not check for NTPSOct94.  For a workaround, use a sed(1) command to replace 'NTPSOct94' with 'NTPSOct95', like so:
	      sed 's/NTPSOct94/NTPSOct95/g'
       This is particularly important for Windows NT 3.5 users.

AUTHOR

       fixnt   was   written   by   Holger   Bauer   <Holger.Bauer@topmail.de>,  Michael  Rath	<rath@itsm.uni-stuttgart.de>,  and  Akim  Demaille
       <demaille@inf.enst.fr>.

REPORTING BUGS

       Report bugs to the Authors, but avoid sending large postscript files.

       Patches are always welcome; send to <bauer@itsm.uni-stuttgart.de>.
