using awk to get specific section of lines in logs
i have a log file that has the date and time that looks like this:
Code:
Wed Jun 28 15:46:21 2012 test failed tailed passed passed not error panic
what we want to focus on is the first 5 columns because they contain the date and time.
the date and time can be anywhere on the line. in this particular case, the date and time is at the beginning of the line. my question is, what happens if it is somewhere else on that line? how can i make it so that when i run a one liner awk command, it finds the date and time wherever it is on the line?
I have this files:
./frm/lf_mt1_cd.Ic_cell_template.attr
./die/addgen_tb_pumd.Ic_cell_template.attr
./min_m1_n.Ic_cell_template.attr
When I use:
awk -F\/ '{print NF}'
Would result to:
3
3
2
I would like to list the files with 3 fields on it. Any Suggestions? (1 Reply)
Hi!

I have a small awk-script that finds specific rows in a file and saves the line number in an array, like this:
awk '
BEGIN { count=0}
/ZZZZ/ {
list=NR

FBB::mlm(3bobcat) OFoldStream manipulator FBB::mlm(3bobcat)NAME
FBB::mlm - Manipulator modifying left margins of OFoldStream objects
SYNOPSIS
#include <bobcat/ofoldstream> or
#include <bobcat/ofoldstreambuf>
Linking option: -lbobcat
DESCRIPTION
The mlm class implements a manipulator that can be inserted into OFoldStream objects to modify the stream's left margin by a requested
amount. The request cannot result in a negative left margin value. If a negative left margin would be the arithmetic result of the request
then left margin 0 will silently be used.
Depending on the tab-setting of the OFoldStream the inserted value represents the number of blank space characters or the number of
tab-characters that will be added to the left margin.
The request will be processed at the next newline character or std::flush or std::endl manipulator that is inserted into the stream. If a
line is still empty once an mlm object and a flush manipulator are inserted into the stream then the new left margin will be effective at
the next word inserted into that line (cf., the example section below)
A bad_cast exception is thrown when the manipulator is inserted into an ostream that is not using a OFoldStreambuf buffer.
