Hi, all:

Under each, there are thousands of files.
It's quite obvious that there are some files missing in each. I just would like to find them. I believe this can be done by "diff" command.
However, if I change the above question a... (1 Reply)

awk 'NR==FNR{a=$1;next} a' file1 file2

hi all,
Thanks to all for your great help...
I have a scenario that I have two files (file1 & file2). I need to compare two files entire row by row and share the output if any discrepancies within two files.
File1:
DB1|TB1|C1,C3
DB2|TB2|C1,C2
DB3|TB3|C1,C2,C3,C4

merge
MERGE(1) General Commands Manual MERGE(1)NAME
merge - three-way file merge
SYNOPSIS
merge [ options ] file1 file2 file3
DESCRIPTION
merge incorporates all changes that lead from file2 to file3 into file1. The result ordinarily goes into file1. merge is useful for com-
bining separate changes to an original. Suppose file2 is the original, and both file1 and file3 are modifications of file2. Then merge
combines both changes.
A conflict occurs if both file1 and file3 have changes in a common segment of lines. If a conflict is found, merge normally outputs a
warning and brackets the conflict with <<<<<<< and >>>>>>> lines. A typical conflict will look like this:
<<<<<<< file A
lines in file A
=======
lines in file B
>>>>>>> file B
If there are conflicts, the user should edit the result and delete one of the alternatives.
OPTIONS -A Output conflicts using the -A style of diff3(1), if supported by diff3. This merges all changes leading from file2 to file3 into
file1, and generates the most verbose output.
-E, -e These options specify conflict styles that generate less information than -A. See diff3(1) for details. The default is -E. With
-e, merge does not warn about conflicts.
-L label
This option may be given up to three times, and specifies labels to be used in place of the corresponding file names in conflict
reports. That is, merge -L x -L y -L z a b c generates output that looks like it came from files x, y and z instead of from files
a, b and c.
-p Send results to standard output instead of overwriting file1.
-q Quiet; do not warn about conflicts. -V Print 's version number.
DIAGNOSTICS
Exit status is 0 for no conflicts, 1 for some conflicts, 2 for trouble.

BUGS
It normally does not make sense to merge binary files as if they were text, but merge tries to do it anyway.
