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?

grep
GREP(1) General Commands Manual GREP(1)NAME
grep - search a file for a pattern
SYNOPSIS
grep [ option ... ] pattern [ file ... ]
DESCRIPTION
Grep searches the input files (standard input default) for lines (with newlines excluded) that match the pattern, a regular expression as
defined in regexp(6). Normally, each line matching the pattern is `selected', and each selected line is copied to the standard output.
The options are
-c Print only a count of matching lines.
-h Do not print file name tags (headers) with output lines.
-i Ignore alphabetic case distinctions. The implementation folds into lower case all letters in the pattern and input before interpre-
tation. Matched lines are printed in their original form.
-l (ell) Print the names of files with selected lines; don't print the lines.
-L Print the names of files with no selected lines; the converse of -l.
-n Mark each printed line with its line number counted in its file.
-s Produce no output, but return status.
-v Reverse: print lines that do not match the pattern.
Output lines are tagged by file name when there is more than one input file. (To force this tagging, include /dev/null as a file name
argument.)
Care should be taken when using the shell metacharacters $*[^|()= and newline in pattern; it is safest to enclose the entire expression in
single quotes '...'.

Exit status is null if any lines are selected, or non-null when no lines are selected or an error occurs.
