The solution shared by you is very impressive..... but in case if file1 has same lines multiple times (which is common to other files as well) then it will result in multiple occurrence of that line in output.
Maybe we can use sort and unique to overcome this little problem somewhat like:
and then apply while loop on this tmp. file
Hi,

Any help is appreciated.

Hi,
I'm using AWK to try to extract data from multiple files (*.txt). The script should look for a flag that occurs at a specific position in each file and it should return the data to the right of that flag.
I should end up with one line for each file, each containing 3 columns:... (8 Replies)
Hi,

I have two (or more, to make it generic) csv files. Each line contains words separated by comma. None of words have any space. The number of words per line is not fixed. Some may have one, and some may have 12... The number of lines per file is also not fixed.
What I need is to find common words... (1 Reply)
Hello everyone
A few years Ago the user radoulov posted a fancy solution for a problem, which was about finding common lines (gene variation names) between multiple samples (files). The code was:
awk 'END {
for (R in rec) {
n = split(rec, t, "/")
if (n > 1)
dup = dup ?... (5 Replies)
I have this code
awk 'NR==FNR{a=$1;next} a' file1 file2
which does what I need it to do, but for only two files. I want to make it so that I can have multiple files (for example 30) and the code will return only the items that are in every single one of those files and ignore the ones... (7 Replies)

diff3
DIFF3(1) General Commands Manual DIFF3(1)NAME
diff3 - 3-way differential file comparison
SYNOPSIS
diff3 [ -ex3 ] file1 file2 file3
DESCRIPTION
Diff3 compares three versions of a file, and publishes disagreeing ranges of text flagged with these codes:
==== all three files differ
====1 file1 is different
====2 file2 is different
====3 file3 is different
The type of change suffered in converting a given range of a given file to some other is indicated in one of these ways:
f : n1 a Text is to be appended after line number n1 in file f, where f = 1, 2, or 3.
f : n1 , n2 c Text is to be changed in the range line n1 to line n2. If n1 = n2, the range may be abbreviated to n1.
The original contents of the range follows immediately after a c indication. When the contents of two files are identical, the contents of
the lower-numbered file is suppressed.
Under the -e option, diff3 publishes a script for the editor ed that will incorporate into file1 all changes between file2 and file3, i.e.
the changes that normally would be flagged ==== and ====3. Option -x (-3) produces a script to incorporate only changes flagged ====
(====3). The following command will apply the resulting script to `file1'.
(cat script; echo '1,$p') | ed - file1
FILES
/tmp/d3?????
/usr/lib/diff3
SEE ALSO diff(1)BUGS
Text lines that consist of a single `.' will defeat -e.
Files longer than 64K bytes won't work.
