The purpose is to find the element in either array (union), and in both array (intersection). Thank you in advance.
@a=qw(1 3 5 6 7 8);
@b=qw(2 3 5 7 9);
foreach $e (@a, @b) {$union{$e}++ &&... (3 Replies)

Hi group,
Can you please tell how to delete specific columns from a file.
I know something like
awk -F, '{ print $1" "$2" "15 }' input.txt > output.txt will delete all other columns. But this is in a way to copy some particular columns.
But is there any other way to select just some... (11 Replies)

Hi,
I like to intersect two files based on their first columns. Here is the code which does the trick for me:
awk 'NR==FNR{A;next}$1 in A' file1 file2
However, this only looks for exact matches between the two files in the first column. I need them to be printed even if part of the string... (10 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.
