Or a very small tweek to the original code I posted:
If you're needing this from a compiled programme, I'd do the work in the programme.
Wow, that code was impressive...
It's exactly what i wanted !
The code that i use with .txts has a little problems with columns...it's not lined up..
But this is perfect i think ...!
I don't know maybe it's a little too "specialized" for my project but thanks it's really educational..
Only a question, if i need to run this command inside a C programm under UNIX shell i should use the system(); and put inside the parenthesis the command??
Anyway thanks!

HELLO! This is my first post here! By the way, I think it is great that people do this.
My question:
I have two files, one is a .dilm and one is a .txt. It is my understanding that the .dilm file can be treated as a .txt file. I wrote another program where I was able to manipulate it as if it... (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)
I am trying to find a specific set of characters in a long file. I only want to find the characters in column 265 for 4 bytes.
Is there a search for that? I tried cut but couldn't get it to work.
Ex. I want to find '9999' in column 265 for 4 bytes. If it is in there, I want it to print... (12 Replies)
Hi
I have a file which is tab-delimited. Now, I'd like to print the lines which have "chr6" string in both first and second columns. Could anybody help? (3 Replies)
Hi,
I'd like to intersect two files by the 4th col of the first file and 6th col of the second file. This is the code I use:
awk 'NR==FNR{A;next}$6 File1 File2
However, this is only outputting the second file lines. I'd like to have both lines in a single line separated by a tab.
Thanks in... (25 Replies)

PAPI_num_cmp_hwctrs(3) PAPI PAPI_num_cmp_hwctrs(3)NAME
PAPI_num_cmp_hwctrs -
Return the number of hardware counters for the specified component.
SYNOPSIS Detailed Description
PAPI_num_cmp_hwctrs() returns the number of counters present in the specified component. By convention, component 0 is always the cpu.
On some components, especially for CPUs, the value returned is a theoretical maximum for estimation purposes only. It might not be possible
to easily create an EventSet that contains the full number of events. This can be due to a variety of reasons: 1). Some CPUs (especially
Intel and POWER) have the notion of fixed counters that can only measure one thing, usually cycles. 2). Some CPUs have very explicit rules
about which event can run in which counter. In this case it might not be possible to add a wanted event even if counters are free. 3). Some
CPUs halve the number of counters available when running with SMT (multiple CPU threads) enabled. 4). Some operating systems 'steal' a
counter to use for things such as NMI Watchdog timers. The only sure way to see if events will fit is to attempt adding events to an
EventSet, and doing something sensible if an error is generated.
PAPI_library_init() must be called in order for this function to return anything greater than 0.
C Interface:
#include <papi.h>
int PAPI_num_cmp_hwctrs(int cidx );
Parameters:
cidx -- An integer identifier for a component. By convention, component 0 is always the cpu component.
Example
* // Query the cpu component for the number of counters.
* printf(
*
Returns:
On success, this function returns a value greater than zero.
A zero result usually means the library has not been initialized.
