The only difference is that my program sorts as per frequency: highest to lowest, but that is not a big issue.
How does one massage a numeric data in awk to sort data in terms of frequency.
Thanks once again
I am trying to merge two large file horizontally using paste command. Every thing is working fine except for time. Its taking lot of time.
Is there any effiecient way of doing the same thing or is there anyway by which I can improve its perfomance programatically?
Thanks,

c 234 sfdr
fil2.txt
b 345 hgy
d 4653 jgut
I want to merger in such a manner the the output file should be
outfile.txt
a 123 aqsw
b 345 hgy
c 234 sfdr
d 4653 jgut

My file looks like this
The first 2 sequences are identical (different ID and frequencies though). The same thing for the last 2. What I need is to compare all sequences within the file and if they are identical, they need to be 'compressed' to one entry and the frequency should be recalculated.... (8 Replies)

Our university has upgraded its version of a computational chemistry program that our group uses quite regularly. In the past we have been able to extract frequency spectra from log files that are generated. Since the upgrade, the viewing program errors out. I've been able to trace down the changes...

pipe
pipe(2) System Calls Manual pipe(2)NAME
pipe() - create an interprocess channel
SYNOPSIS DESCRIPTION
creates an I/O mechanism called a pipe and returns two file descriptors, fildes[0] and fildes[1]. fildes[0] is opened for reading and
fildes[1] is opened for writing.
A read-only file descriptor fildes[0] accesses the data written to fildes[1] on a first-in-first-out (FIFO) basis. For details of the I/O
behavior of pipes see read(2) and write(2).
By default, HP-UX pipes are not STREAMS-based. It is possible to generate the kernel so that all pipes created on a system are STREAMS-
based. This can only be done for HP-UX releases 10.0 and later. STREAMS-based FIFOs (created by or are not supported on HP-UX.
To generate a kernel that supports STREAMS-based pipes:
o STREAMS/UX must be installed.
o The module and the driver must be included in the file. (When STREAMS/UX is installed, and are automatically added to the system
file.)
o The tunable parameter (see streampipes(5)) must be set to 1 in the file. (This is not automatically done when STREAMS/UX is
installed.)
o The kernel must be generated and the system rebooted. Once this is done, all pipes created by will be STREAMS-based.

EXAMPLES
The following example uses to implement the command string
RETURN VALUE
returns one of the following values:
Successful completion.
Failure.
is set to indicate the error.
ERRORS
sets to one of the following error values if the corresponding condition is true.
or more file descriptors are currently open.
The system file table is full.
The file system lacks sufficient space to create the pipe.
Could not allocate resources for both Stream heads
(STREAMS-based pipes only).
