I have a file that has multiple lines, of grouped data, that typically all have the same values in the 1st field, however, I would like to search the 1st field for any differences and set a flag to use in an "if" statement to run some other routine.
An example of the typical file is below, which is a comma separated file:
I want to set a flag for each data set of the 3rd field, if the file has differences in the 1st field like below:
One method I've tried so far is to strip out the lines where the 3rd field is all the same, and then try to run through each line and check the 1st field for differences.
I've tried the following, but can't get it to work.

I have two files. They are prety much the same, except a few lines. I would like to get the differences between the two file, but only those differences and nothing more.
"diff" and "sdiff" cannot seem to do it. "sdiff -s" gets close, but I still get "less than" or "greater than" signs in the... (2 Replies)

Hi,
I have a file in the following format
a1 b1 c1 d1
a2 b2 c2 d2
a3 b3 c3 d3
a4 b4 c4 d4
I need a script to find the difference between corresponding values of successive rows. So the output would have one less row than the input file and should look like:
a2-a1 b2-b1 c2-c1 d2-d1... (4 Replies)

Hi!
I'd like to know if it is possible for a command to find the first difference between two large files, output that line from both file and stop, so no need to continue after that to save some computation time.
I don't think looping through it will be efficient enough but that's the only... (6 Replies)

msgb
msgb(9S) Data Structures for Drivers msgb(9S)NAME
msgb, mblk - STREAMS message block structure
SYNOPSIS
#include <sys/stream.h>
INTERFACE LEVEL
Architecture independent level 1 (DDI/DKI)
DESCRIPTION
A STREAMS message is made up of one or more message blocks, referenced by a pointer to a msgb structure. The b_next and b_prev pointers
are used to link messages together on a QUEUE. The b_cont pointer links message blocks together when a message consists of more than one
block.
Each msgb structure also includes a pointer to a datab(9S) structure, the data block (which contains pointers to the actual data of the
message), and the type of the message.
STRUCTURE MEMBERS
struct msgb *b_next; /* next message on queue */
struct msgb *b_prev; /* previous message on queue */
struct msgb *b_cont; /* next message block */
unsigned char *b_rptr; /* 1st unread data byte of buffer */
unsigned char *b_wptr; /* 1st unwritten data byte of buffer */
struct datab *b_datap; /* pointer to data block */
unsigned char b_band; /* message priority */
unsigned short b_flag; /* used by stream head */
Valid flags are as follows:
MSGMARK Last byte of message is marked.
MSGDELIM Message is delimited.
The msgb structure is defined as type mblk_t.
