Hi there,
I'm trying to merge two files and make a third file.
However, two of the columns need to match exactly in both files AND I want everything from both files in the output if the two columns match in that row.
First file looks like this:
chr1 10001980 T A

I have this text file with a very large number of columns (10,000+) and I want to move the first column to the position of the six column so that the text file looks like this:

Hi,
I have a tab delimited text file with multiple columns. The second and third columns include numbers that have not been sorted. I want to extract rows where the second column includes a value between -0.01 and 0.01 (including both numbers) and the first third column includes a value between... (1 Reply)
Hi,
I am not so familiar with bash scripting and would appreciate your help here.
I have a text file 'input.txt' like this:
2 3 4
5 6 7
8 9 10
I want to store each column in an array like this
a ={2 5 8}, b={3 6 9}, c={4 7 10}
so that i can access any element, e.g b=6 for the later use. (1 Reply)
Hi to all,
I have two files. File1 has no header, two columns:
sample1 A
sample2 B
sample3 B
sample4 C
sample5 A
sample6 D
sample7 D

I have this code below that only prints out certain columns from the first two rows (doesn't affect rows 3 and beyond). How can I do the same on a partial header pattern “G_TP” instead of having to know specific column numbers (e.g. 374-479)? I've tried many other commands within this pipe with no... (4 Replies)
Hello,
I have to fish out some specific columns from a file based on the header value. I have the list of columns I need in a different file. I thought I could read in the list of headers I need,
# file with header names of required columns in required order
headers_file=$2
# read contents... (11 Replies)
I've been struggling with this one for quite a while and cannot seem to find a solution for this find/replace scenario. Perhaps I'm getting rusty.
I have a file that contains a number of metrics (exactly 3 fields per line) from a few appliances that are collected in parallel. To identify the... (3 Replies)

join
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 file1 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.
Fields are normally separated by blank, tab or newline. In this case, multiple separators count as one, and leading separators are dis-
carded.
These options are recognized:
-an In addition to the normal output, produce a line for each unpairable line in file n, where n is 1 or 2.
-e s Replace empty output fields by string s.
-jn m Join on the mth field of file n. If n is missing, use the mth field in each file.
-o list
Each output line comprises the fields specifed in list, each element of which has the form n.m, where n is a file number and m is a
field number.
-tc Use character c as a separator (tab character). Every appearance of c in a line is significant.
SEE ALSO sort(1), comm(1), awk(1)BUGS
With default field separation, the collating sequence is that of sort -b; with -t, the sequence is that of a plain sort.
The conventions of join, sort, comm, uniq, look and awk(1) are wildly incongruous.
