If $1 in file1 matches $2 in file2. Then the value in $2 of file2 is updated to $1"."$2 of file2. The awk seems to only match the two files but not update. Thank you :).

I am trying to use awk to match two files that are tab-delimited. When a match is found between file1 $1 and file2 $4, $4 in file2 is updated using the $2 value in file1. If no match is found then the next line is processed. Thank you :).

I am trying to use awk to match the NM_ in file with $1 of id which is tab-delimited. The NM_ will always be in the line of file that starts with > and be after the second _. When there is a match between each NM_ and id, then the value of $2 in id is substituted or used to update the NM_. Each NM_... (3 Replies)

In the out.txt below I am trying to use awk to update the contents of $9.. If $9 contains a + or - then $8 of out.txt is used as a key to lookup in $2 of file. When a match ( there will always be one) is found the $3 value of that file is used to update $9 of out.txt separated by a :. So the... (6 Replies)
In the awk, thanks you @RavinderSingh13, for the help in below, hopefully it is close as I am trying to update the value in $12 of the tab-delimeted file2 with the matching value in $1 of the space delimeted file1. I have added comments for each line as well. Thank you :).

Trying to use awk to store the value of $5 in file1 in array x. That array x is then used to search $4 of file1 to find aa match (I use x to skip the header in file1).

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 one of the file names 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.
Input fields are normally separated spaces or tabs; output fields by space. In this case, multiple separators count as one, and leading
separators are discarded.
The following options are recognized, with POSIX syntax.
-a n In addition to the normal output, produce a line for each unpairable line in file n, where n is 1 or 2.
-v n Like -a, omitting output for paired lines.
-e s Replace empty output fields by string s.
-1 m
-2 m Join on the mth field of file1 or file2.
-jn m Archaic equivalent for -n m.
-ofields
Each output line comprises the designated fields. The comma-separated field designators are either 0, meaning the join field, or
have the form n.m, where n is a file number and m is a field number. Archaic usage allows separate arguments for field designators.
-tc Use character c as the only separator (tab character) on input and output. Every appearance of c in a line is significant.
EXAMPLES
sort /adm/users | join -t: -a 1 -e "" - bdays
Add birthdays to password information, leaving unknown birthdays empty. The layout of is given in users(6); bdays contains sorted
lines like
tr : ' ' </adm/users | sort -k 3 3 >temp
join -1 3 -2 3 -o 1.1,2.1 temp temp | awk '$1 < $2'
Print all pairs of users with identical userids.
SOURCE

SEE ALSO sort(1), comm(1), awk(1)BUGS
With default field separation, the collating sequence is that of sort -b -ky,y; with -t, the sequence is that of sort -tx -ky,y.
One of the files must be randomly accessible.
