Hi guys,
I checked the knowledge base before posting this question.
is there any way by which you can ALWAYS ALLOW file overwrite in AWK?. i.e. an option similar to noclobber in Korn shell.
I don't to check for files existence and remove them. (1 Reply)

Hi, all:
I've got two folders, say, "folder1" and "folder2".
Under each, there are thousands of files.
It's quite obvious that there are some files missing in each. I just would like to find them. I believe this can be done by "diff" command.
However, if I change the above question a... (1 Reply)

I have this code
awk 'NR==FNR{a=$1;next} a' file1 file2
which does what I need it to do, but for only two files. I want to make it so that I can have multiple files (for example 30) and the code will return only the items that are in every single one of those files and ignore the ones... (7 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.
