How about...
IPA is array of IP fields. Change '*' to 0 through 3 for individual fields.
I wonder if AWK would run faster with a line pattern match rather than an IF statement but it would require careful substitution. Have to use double quotes to get shell $1 into AWK and then escape AWK double quotes and dollar signs.
I was able to use the first suggestion! I appreciate the help.
Scrutinizer,
In the example csv file I gave... I only listed the two fields I was working with, the actual csv has 22 fields; and some of the host names are used in other fields in other records. So I have to use the if statement or ill get duplicate entries... its also not the first field so even with the "^" ill still get duplicates.
Hi, all
I need to get fields in a line that are separated by commas, some of the fields are enclosed with double quotes, and they are supposed to be treated as a single field even if there are commas inside the quotes.

I know that windows uses CRLF as a end of line character while Unix uses LF. But visually i could not see any difference in files while creating on either of plat forms.
CR (Carriage Return) means to bring cursor to beginning of line while LF (Line feed) means to bring cursor to next line... (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.

snsplit
snsplit,v0.3.8(8) System Manager's Manual snsplit,v0.3.8(8)NAME
snsplit - split an article stream into individual articles
SYNOPSIS
snsplit [-r] [field... -] prog...
DESCRIPTION
snsplit reads an article stream from descriptor 0 and splits it into separate articles, invoking prog... on each, with the article ava-
iable on descriptor 0. This is useful as a quick-and-dirty way of filtering an article stream.
The incoming article stream is expected to be in wire format, with lines ending in CRLF, leading dots doubled, and delimited by a dot on a
line by itself.
The article presented to prog... will have lines that end in a bare newline, will have all header lines unfolded, leading dots will be
unstuffed, and the article will be terminated by end-of-file.
ARGUMENTS
prog...
is the program (with arguments) to run on each article. If prog... exits with any kind of failure, snsplit aborts.
field...-
are optional header field names. If these are specified, the value of the first header field of that name will be exported into the
environment. This field... list must be terminated by the hyphen. See also ENVIRONMENT below.
OPTIONS -r Expect input articles in rnews batch format instead.
ENVIRONMENT
snsplit sets some environment variables. If the environment already contains these variables, they will be overwritten.
SEQUENCE
If already set to a positive value, it is incremented for the first article. If it isn't set, is set to one for the first article.
Thereafter it is incremented for each subsequent article. The value is always a 6-digit number with leading zeroes, and it can roll
over.
BYTES contains the size of the current article.
HEAD_LINES
The number of lines in the head of the article, excluding the blank separator line.
BODY_LINES
The number of lines in the body of the article, excluding the blank separator line.
FLD_FIELD
If any fields are specified on the command line, where field is the name of an article header field, then FLD_FIELD will be set to
the value of field, where FIELD is the same as field but with lower case characters changed to upper case, and all hyphens changed
to underscores. Confusing? If field is message-id, then FLD_MESSAGE_ID will be set to the value of the first Message-ID field in
the current article, if there is one.
EXIT CODES
snsplit exits 0 on success, 1 on usage error, 2 on system error, and 3 on article format error. If prog... exits with other than 0,
snsplit will also exit that value.
