but that doesn't do anything
also tried

Hi,
let's say an input looks like:
A|C|C|D
A|C|I|E
A|B|I|C
A|T|I|B
as the title of the thread explains, I am trying to get something like:
1|A=4
2|C=2|B=1|T=1
3|I=3|C=1
4|D=1|E=1|C=1|B=1
i.e. a count of every character in each field (first column of output) independently, sorted... (4 Replies)

In the awk below I am trying to copy the entire contents of $6 there may be multiple values seperated by a ;, to $8, if $8 is . (lines 1 and 3 are examples). If that condition $8 is not . (line2 is an example) then that line is skipped and printed as is. The awk does execute but prints the output... (3 Replies)
The below awk executes as is and produces the current output. It isvery close but what Ican not seem to do is add the -exon..., the ... portion comes from $1 and the _exon is static and will never change. If there is + sign in $4 then the ... is in acending order or sequential. If there is a - in... (2 Replies)
Hi,
Sure it's an easy one, but it drives me insane.

3|A,B,B
I would like to count the occurence of each capital letters in $2 across the entire file, knowing that duplicates in each record count as 1.
I am trying to get this output... (5 Replies)
Hi,
So awk is driving me crazy on this one. I have searched everywhere and read man, docs and every related post Google can find and still no luck. The actual files I need to run this on are sensitive in nature, but it is the same thing as if I needed to calculate weighted grades for multiple... (15 Replies)

snp
SNP(4) BSD Kernel Interfaces Manual SNP(4)NAME
snp -- tty snoop interface
SYNOPSIS
#include <sys/snoop.h>
int
ioctl(fd, SNPSTTY, &dev);
int
ioctl(fd, SNPGTTY, &dev);
int
ioctl(fd, FIONREAD, &result);
DESCRIPTION
/dev/snp is a snoop device which allows users to attach to any tty and watch activities on it. The kernel must be compiled with device snp,
or the snp module must be loaded, for these devices to be available.
To associate a given snp device with a tty to be observed, open the snp device and a tty device, and then issue the SNPSTTY ioctl on snp
device. The argument passed to the ioctl(2) is the address of a variable of type int, holding the file descriptor of a tty device. To
detach the snp device from a tty use a pointer to a value of -1.
The SNPGTTY ioctl returns information about the current tty attached to the open snp device.
The FIONREAD ioctl returns a positive value equal to the number of characters in a read buffer. Special values defined are:
SNP_OFLOW device overflow occurred, device detached.
SNP_TTYCLOSE tty not attached.
SNP_DETACH snp device has been detached by user or tty device has been closed and detached.
SEE ALSO pty(4), sio(4), kldload(8), watch(8)HISTORY
The snp device first appeared in FreeBSD 2.1. In FreeBSD 8.0 the snp driver was rewritten to work with the replaced TTY subsystem.
AUTHORS
The author of the current implementation is Ed Schouten <ed@FreeBSD.org>. Previous versions of snp were based on code written by
Ugen J.S. Antsilevich <ugen@NetVision.net.il>.
BUGS
This version of snp does not return proper error codes when calling FIONREAD. It also does not allow SNPSTTY to detach itself from the TTY.
