Hello!
I am writing a program to run through two large lists of data (~300,000 rows), find where rows in one file match another, and combine them based on matching fields. Due to the large file sizes, I'm guessing AWK will be the most efficient way to do this. Overall, the input and output I'm... (5 Replies)
grep -v will exclude matching lines, but I want something that will print all lines but exclude a matching field. The pattern that I want excluded is '/mnt/svn'
If there is a better solution than awk I am happy to hear about it, but I would like to see this done in awk as well. I know I can... (11 Replies)
I am trying to look for $2 of file1 (skipping the header) in $2 of file2 (skipping the header) and if they match and the value in $10 is > 30 and $11 is > 49, then print the line from file1 to a output file. If no match is foung the line is not printed. Both the input and output are tab-delimited.... (3 Replies)
In the below I am trying to use awk to match all the $13 values in input, which is tab-delimited,
that are in $1 of gene which is just a single column of text.
However only the line with the greatest $9 value in input needs to be printed.
So in the example below all the MECP2 and LTBP1... (0 Replies)

Hi,
I have 2 tab-delimited input files as follows.
file1.tab:
green A apple
red B apple
file2.tab:
apple - A;Z
Objective:
Return $1 of file1 if,
. $1 of file2 matches $3 of file1 and,
. any single element (separated by ";") in $3 of file2 is present in $2 of file1
In order to... (3 Replies)
In the awk below I am trying to output those lines that Match between file1 and file2, those Missing in file1, and those missing in file2. Using each $1,$2,$4,$5 value as a key to match on, that is if those 4 fields are found in both files the match, but if those 4 fields are not found then missing... (0 Replies)
I've written an awk script to compare two fields in two different files and then print portions of each file on the same line when matched. It works reasonably well, but every now and again, I notice some errors and cannot seem to figure out what the issue may be and am turning to you for help.

Hi, I have two TEST files t.xyz and a.xyz which have three columns each. a.xyz have more rows than t.xyz. I will like to output rows at which $1 and $2 of t.xyz match $1 and $2 of a.xyz. Total number of output rows should be equal to that of t.xyz.
It works fine, but when I apply it to large... (6 Replies)

join
join(1) General Commands Manual join(1)NAME
join - relational database operator
SYNOPSIS
[options] file1 file2
DESCRIPTION
forms, on the standard output, a join of the two relations specified by the lines of file1 and file2. If file1 or file2 is the standard
input is used.
file1 and file2 must be sorted in increasing collating sequence (see Environment Variables below) on the fields on which they are to be
joined; normally the first in each line.
The output contains one line for each pair of lines in file1 and file2 that have identical join fields. The output line normally consists
of the common field followed by the rest of the line from file1, then the rest of the line from file2.
The default input field separators are space, tab, or new-line. In this case, multiple separators count as one field separator, and lead-
ing separators are ignored. The default output field separator is a space.
Some of the below options use the argument n. This argument should be a or a referring to either file1 or file2, respectively.
Options
In addition to the normal output,
produce a line for each unpairable line in file n, where n is or
Replace empty output fields by string
s.
Join on field
m of both files. The argument m must be delimited by space characters. This option and the following two are provided for
backward compatibility. Use of the and options ( see below ) is recommended for portability.
Join on field
m of file1.
Join on field
m of file2.
Each output line comprises the fields specified in
list, each element of which has the form where n is a file number and m is a field number. The common field is not printed
unless specifically requested.
Use character
c as a separator (tab character). Every appearance of c in a line is significant. The character c is used as the field sepa-
rator for both input and output.
Instead of the default output,
produce a line only for each unpairable line in file_number, where file_number is or
Join on field
f of file 1. Fields are numbered starting with 1.
Join on field
f of file 2. Fields are numbered starting with 1.
EXTERNAL INFLUENCES
Environment Variables
determines the collating sequence expects from input files.
determines the alternative blank character as an input field separator, and the interpretation of data within files as single and/or multi-
byte characters. also determines whether the separator defined through the option is a single- or multi-byte character.
If or is not specified in the environment or is set to the empty string, the value of is used as a default for each unspecified or empty
variable. If is not specified or is set to the empty string, a default of ``C'' (see lang(5)) is used instead of If any internationaliza-
tion variable contains an invalid setting, behaves as if all internationalization variables are set to ``C'' (see environ(5)).
International Code Set Support
Single- and multi-byte character code sets are supported with the exception that multi-byte-character file names are not supported.
EXAMPLES
The following command line joins the password file and the group file, matching on the numeric group ID, and outputting the login name, the
group name, and the login directory. It is assumed that the files have been sorted in the collating sequence defined by the or environment
variable on the group ID fields.
The following command produces an output consisting all possible combinations of lines that have identical first fields in the two sorted
files sf1 and sf2, with each line consisting of the first and third fields from and the second and fourth fields from
WARNINGS
With default field separation, the collating sequence is that of with the sequence is that of a plain sort.
The conventions of and are incongruous.
Numeric filenames may cause conflict when the option is used immediately before listing filenames.
