I've read all the articles that have anything to do with c shell.
And they don't say that there isn't any solution, they say that there is a solution, but it's messy, long and ugly.
But I have the solution to my problem, and I'll write it down for all the future head-breakers. It is so simple, and I can't believe I didn't think about it myself (McCartney says it better - "With a little help from my friends"):
When you want to compare a word from a column in one file to a word from another column in another file, you simply do this (for any i, j you choose):
Code:
set list1 = `cut -d" " -fi ${1}`
set list2 = `cut -d" " -fj ${2}`
#We simply "crop" all the words in field i (in the first file) into a list called list1,
#and the same for the second file. Notice the back quotes!
So what was my head-on-the-wall-banging about?
Well, I thought about doing that, but since there isn't any single-charactered showcase for enter (\n) (for what I know of), I didn't think it would work. So what's the trick? The cut command, by definition, goes through each line until it reaches the end of the file, so out of each line it only takes the word in your chosen field and puts it in the list by order.
If there's anyone who wants to read the full program, you're welcome to leave me messages with your e-mail.
What's the lesson? Always check your ideas before eliminating them.

comm
comm(1) User Commands comm(1)NAME
comm - select or reject lines common to two files
SYNOPSIS
comm [-123] file1 file2
DESCRIPTION
The comm utility reads file1 and file2, which must be ordered in the current collating sequence, and produces three text columns as output:
lines only in file1; lines only in file2; and lines in both files.
If the input files were ordered according to the collating sequence of the current locale, the lines written will be in the collating
sequence of the original lines. If not, the results are unspecified.
OPTIONS
The following options are supported:
-1 Suppresses the output column of lines unique to file1.
-2 Suppresses the output column of lines unique to file2.
-3 Suppresses the output column of lines duplicated in file1 and file2.
OPERANDS
The following operands are supported:
file1 A path name of the first file to be compared. If file1 is -, the standard input is used.
file2 A path name of the second file to be compared. If file2 is -, the standard input is used.
USAGE
See largefile(5) for the description of the behavior of comm when encountering files greater than or equal to 2 Gbyte ( 2**31 bytes).
EXAMPLES
Example 1: Printing a list of utilities specified by files
If file1, file2, and file3 each contain a sorted list of utilities, the command
example% comm -23 file1 file2 | comm -23 - file3
prints a list of utilities in file1 not specified by either of the other files. The entry:
example% comm -12 file1 file2 | comm -12 - file3
prints a list of utilities specified by all three files. And the entry:
example% comm -12 file2 file3 | comm -23 -file1
prints a list of utilities specified by both file2 and file3, but not specified in file1.
ENVIRONMENT VARIABLES
See environ(5) for descriptions of the following environment variables that affect the execution of comm: LANG, LC_ALL, LC_COLLATE,
LC_CTYPE, LC_MESSAGES, and NLSPATH.
EXIT STATUS
The following exit values are returned:
0 All input files were successfully output as specified.
>0 An error occurred.
