The first awk is always the case. The only thing that may change is the output (depending on the case). How can I print only $5, $6, $7 ? Thank you for your help, iworks great .
I am trying to break a string into separate fields and print the field that matches a pattern. I am using awk at the moment and have gotten this far:
awk '{for(i=1;i<=NF;++i)print "\t" $i}' longstring
This breaks the string into fields and prints each field on a separate line.

Trying to combine strings that are a partial match to another in $1 (usually below it). If a match is found than the $2 value is added to the $2 value of the match and the $3 value is added to the $3 value of the match. I am not sure how to do this and need some expert help. Thank you :).

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.

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). Since $4 can have multiple strings in it seperated by a , (comma), I split them and iterate througn each split looking for a match.... (2 Replies)

join
JOIN(1) General Commands Manual JOIN(1)NAME
join - relational database operator
SYNOPSIS
join [-an] [-e s] [-o list] [-tc] 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.
-o list
Each output line comprises the fields specified 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.
