How about this:
BEGIN block removes files "ones" and "two" (just incase they are already there from previous run of awk program).
You could also do this in the shell before calling awk, and have the program always append to ones and two if they are already there.
Note any line that contains a value other than 1 or 2 in field 8 is just ignored.
Hi,
I'm attempting to search, using awk, a pattern range in a file. Something like:
>awk '/first bit of text.../,/...last bit of text/' file
Is it possible to print only the last (or first) occurrence of the pattern range this way?
Thanks for any suggestions.

Now it fills the array with every file it finds so in the end the output of some users contains up to 200.000 numbers. So how can I calculate... (7 Replies)

Hello,
I came across a previous thread "awk-calculating-simple-correlation-rows" which calculated correlations across rows in awk.
Code:
awk '{
a = 0; for (i = 2; i <= NF; ++i) a += $i; a /= NF-1
b = 0; for (i = 2; i <= NF; ++i) b += ($i - a) ^ 2; b = sqrt(b)

test::use::ok
Test::use::ok(3) User Contributed Perl Documentation Test::use::ok(3)NAME
Test::use::ok - Alternative to Test::More::use_ok
SYNOPSIS
use ok 'Some::Module';
DESCRIPTION
According to the Test::More documentation, it is recommended to run "use_ok()" inside a "BEGIN" block, so functions are exported at
compile-time and prototypes are properly honored.
That is, instead of writing this:
use_ok( 'Some::Module' );
use_ok( 'Other::Module' );
One should write this:
BEGIN { use_ok( 'Some::Module' ); }
BEGIN { use_ok( 'Other::Module' ); }
However, people often either forget to add "BEGIN", or mistakenly group "use_ok" with other tests in a single "BEGIN" block, which can
create subtle differences in execution order.
With this module, simply change all "use_ok" in test scripts to "use ok", and they will be executed at "BEGIN" time. The explicit space
after "use" makes it clear that this is a single compile-time action.
