Simple script editing text files and running commands
Okay this will probably have multiple parts to it but I don't really want to trouble you guys with more help because I'm a total noob so I can just do the first part by hand (it's just editing a few hundred lines of text in a file; I have to do the same thing on each line and I'm sure there's a scripted solution for it but I can spare a couple hours).

So basically I have a file with several hundred lines, and each line is only 2-3 words.

I need the script to do these things in order:

1) kill process1
2) put the 1st line of this file list into already existing text file #1 (requires root to write): the line it needs to write to is like: "option LINE1" where the 1st line has to be written where 'LINE1' is, somewhere in this text file
3) save this text file
4) put the 1st line of this file list into existing text file #2: the line is like "set = { opt1 = LINE1; opt2 = LINE1; opt3 = LINE1; }" and again I want the 1st line to be filled in all where 'LINE1' says
5) save text file
6) start process1
7) run a certain command in shell which will execute a CLI program and leave it running (I don't think it can be run in the background because I tried starting it with the '&' sign at the end and it ran but it didn't connect the way it properly was supposed to)
8) repeat but use the next line in the file list

What programming language would be the quickest and easiest way to write something like this? If it's not shell scripting, sed/awk, etc. please move this thread to the appropriate programming section. It doesn't have to be fancy or anything, just work even if it's dirty

keyhead

keyhead(1)						      General Commands Manual							keyhead(1)

Name
       keyhead - Change FITS or IRAF header keyword names

Synopsis
       keyhead [-hknv] <FITS or IRAF file> kw1=kw1a kw2=kwd2a ... kwn=kwdna

Description
       Change the names of keywords in FITS or IRAF image headers.  Each current image keyword whose entry is to be modified should be followed by
       an equal sign and a second keyword, with no intervening spaces.	If the -r option is used, the value of the second keyword is transfered to
       that  of the first. Otherwise, the name of the first keyword is changed to the second keyword.  To change keywords in a list of files, sub-
       stitute @<listfile> for the file names on the command line.  To change a lot of keywords, put them, one pair separated by an = sign with no
       spaces  per  line, in a file and substitute @<keylistfile> on the command line.	If two @ commands are present, the program will figure out
       which contains file names and which contains keywords.  Lines in a keyword list file which do not contain an = are ignored.

Options
       -h     Write HISTORY line into output header with sethead version, current date and time, and names of keywords set.

       -k     Write KEYHEAD keyword into output header with the keyhead version, current date and time, and names  of  keywords  whose	names  are
	      changed.	If a KEYHEAD keyword already exists, move the old value to a HISTORY line before writing the new value

       -n     Write a new file with an added "e" before the extension.

       -r letter
	      Replace  value of 1st keyword with value of 2nd keyword instead of changing the name of the 1st keyword to the 2nd keyword.  The 2nd
	      keyword remains in the header.  If the 1st keyword does not exist in the header, it is created.

       -v     Print confirmations of each keyword change.
