So you wanted the last occurrence of you pattern in the REVERSED file; not the last occurrence in the file. Try:
You still refuse to answer the question about what should happen if the pattern you're looking for doesn't appear at all, so if I guessed wrong again about what you want in that case, you're on your own to fix it.
And, I'll repeat the usual warning... If you want to try this on a Solaris/SunOS system, change awk to /usr/xpg4/bin/awk, /usr/xpg6/bin/awk, or nawk.
i will take heed of your warning.
if the pattern is not found, i'm totally ok with the code not showing anything at all.
btw, the log format is in the typical syslog format.
I have an awk statement that works but I am calling awk twice and I know there has to be a way to combine the two statements into one. The purpose is to pull out just the ip address from loopback1.

Using these 2 comands to concatenate both outputs into single file:
cat testdata | awk 'BEGIN { FS="\n"; RS=""; } /<pattern1>/ {print}' > testdata1
cat testdata| awk '/<pattern2>/,EOF' >> testdata1
is it possible to combine both "awk" into 1-liner?
pls advise and thanks in advance. (5 Replies)
Hi Everyone,
awk 'BEGIN{print strftime("%c",1272814948)}' | tr -d '\n'

I'm rather new to programming, and am attempting to combine lines from 2 files in a way that is way beyond my expertise - any help would be appreciated!
I need to take a file (file1) and add columns to it from another file (file2). However, a line from file2 should only be added to a given line... (3 Replies)
Hi,
I have the following two awk statements which I'd like to consolidate into one by piping the output from the first into the second awk statement (rather than having to write kat.txt out to a file and then reading back in).

I have a file of 100,000 entries that look like:

Hi, Below command is working as expected, but would like to know how to club the two AWK scripts in the command into one

IGAWK(1) Utility Commands IGAWK(1)NAME
igawk - gawk with include files
SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ...
igawk [ all gawk options ] [ -- ] program-text file ...
DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1).
AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like
@include getopt.awk
in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path.
OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports.
EXAMPLES
cat << EOF > test.awk
@include getopt.awk
BEGIN {
while (getopt(ARGC, ARGV, "am:q") != -1)
...
}
EOF
igawk -f test.awk
