I want to do a field by word (field) comparison of two files File1.txt and File2.txt.
The files contain a list of | (pipe) separated field.
**File 1:
-------------------
File 2:
-------------------
We compare the same line no. in both the files.
Fields in Line 1 of both file match.
In Line 2 all the fields (lll, mmm, nnn, ooo, ppp) donot not match with all fields (rrr, sss, ttt, uuu, vvv) in line 2 of File 2. Similarly the 5th field of 3rd line in both the files donot match.
Hence Line no. 2 and Line no. 3 should get echoed by bash.
Both files will follow an order.
Is this a homework item? It seems like a strange set of requirements for any non-classroom project.
You haven't shown the output that you want from the input given above, but it seems that you are asking for entire lines from File 1 or entire lines from File 2 to be written to standard output if any field is different. If that is the case, why should we compare fields instead of just comparing lines? Comparing lines should get the same results, is easier to program, and probably run faster.
If you are using awk to compare files; why is it important that bash use the echo command to print the results instead of having awk print the results directly?

JOIN(1) General Commands Manual JOIN(1)NAME
join - relational database operator
SYNOPSIS
join [ options ] file1 file2
DESCRIPTION
Join forms, on the standard output, a join of the two relations specified by the lines of file1 and file2. If one of the file names is the
standard input is used.
File1 and file2 must be sorted in increasing ASCII collating sequence on the fields on which they are to be joined, normally the first in
each line.
There is one line in the output for each pair of lines in file1 and file2 that have identical join fields. The output line normally con-
sists of the common field, then the rest of the line from file1, then the rest of the line from file2.
Input fields are normally separated spaces or tabs; output fields by space. In this case, multiple separators count as one, and leading
separators are discarded.
The following options are recognized, with POSIX syntax.
-a n In addition to the normal output, produce a line for each unpairable line in file n, where n is 1 or 2.
-v n Like -a, omitting output for paired lines.
-e s Replace empty output fields by string s.
-1 m
-2 m Join on the mth field of file1 or file2.
-jn m Archaic equivalent for -n m.
-ofields
Each output line comprises the designated fields. The comma-separated field designators are either 0, meaning the join field, or
have the form n.m, where n is a file number and m is a field number. Archaic usage allows separate arguments for field designators.
-tc Use character c as the only separator (tab character) on input and output. Every appearance of c in a line is significant.
EXAMPLES
sort /etc/passwd | join -t: -1 1 -a 1 -e "" - bdays
Add birthdays to the /etc/passwd file, leaving unknown birthdays empty. The layout of /adm/users is given in passwd(5); bdays con-
tains sorted lines like
tr : ' ' </etc/passwd | sort -k 3 3 >temp
join -1 3 -2 3 -o 1.1,2.1 temp temp | awk '$1 < $2'
Print all pairs of users with identical userids.
SOURCE
/src/cmd/join.c
SEE ALSO sort(1), comm(1), awk(1)BUGS
With default field separation, the collating sequence is that of sort -b -ky,y; with -t, the sequence is that of sort -tx -ky,y.
One of the files must be randomly accessible.
