I require one more help here. (Yes, UNIX definitely seems to be fun and useful, and I WILL eventually learn it for myself. But I am now on a different project and don't really have time to go through all the basics. So, I will really appreciate some help.)
I've got two data files.
One has: ID lat lon data1 data2; for ex:
And the other has: ID data3 data4 data5
For example:
There are approximately 2500 IDs but neither has all of them. file1 has few missing, so does file2, but the missing IDs are not necessarily common.
Now I want to make a new file with: ID lat lon data4 ; but ONLY for the IDs that are common in both.
So, for above files it would be:
I searched the forums and there are similar problems which are solved using awk but I could not comprehend the scripts well enough to create my own solution.
Thanks.
see below ... assumes removal of column labels (first row) ... see man comm and man sort ...
steps in the process ...
1. grab and sort IDs from 1st column ($1) of file 1 (pool) and send to temp file (pool.1t)
2. grab and sort IDs from 1st column ($1) of file 2 (pool4) and send to temp file (pool.4t)
3. for each ID common to both files comm -12 file1 file2
> a. grab lon from lon column ($2) in file 1 (pool)
> b. grab lat from lat column ($3) in file 1 (pool)
> c. grab data4 from data4 column ($3) in file 2 (pool4)
> d. echo out values in correct order

You really should start a new thread when you have a new problem... It makes it a lot easier for people who may try to read this thread later figure out what problem later messages in the thread are trying to address.
Assuming that the above two input files are named datfile3 and datfile4, respectively, and that you want the output stored in a file named output; the following simple awk script seems to be a little more direct than Just Ice's proposal:
When you run this script with the above sample input files, the contents of output will be:
which matches the spacing you requested.
As I mentioned before, if you want to run this on a Solaris system, use /usr/xpg4/bin/awk, /usr/xpg6/bin/awk, or nawk instead of /usr/bin/awk or /bin/awk.
Parse all of your required line to different file with awk and then join all of your file with the paste command. With the paste command you can use any kind of seperator also. In this example i used semicolon.
Could it be possible to find common lines between all of the files in one folder? Just like comm -12 . So all of the files two at a time. I would like all of the outcomes to be written to a different files, and the file names could be simply numbers - 1 , 2 , 3 etc. All of the file names contain... (19 Replies)
Hi! I would like to comm -12 with one file and with all of the files in another folder that has a 100 files or more (that file is not in that folder) to find common text lines. I would like to have each case that they have common lines to be written to a different output file and the names of the... (6 Replies)
Dear All,
I have 2 files. If field 1, 2, 4 and 5 matches in both file1 and file2, I want to print the whole line of file1 and file2 one after another in my output file.
File1:

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)
Hello guys,
I need a script to get the common lines from two files with a criteria that if the first two columns match then I keep the maximum value of the 5th column.(tab separated columns) . 3rd and 4th columns corresponds to the row which has highest value for the 5th column.

Hi! I have a large set of pairs of text files (each pair in their own subdirectory) and each pair shares head/tail (a couple of first and last lines) but differs in the middle part. I need to delete the heads/tails and keep only the middle portions in which they differ. The lengths of heads/tails... (1 Reply)
