Command/script to match a field and print the next field of each line in a file.
Hello,
I have a text file in the below format:
And the file has hundreds of such entries.
What I'm interested in is the lag column- which is always in the format hh:mm:ss. I want to read the file line by line, check if the "lag" column in greater than 48:00:00 (just matching the hour field would be enough) and if the lag is greater than 48:00:00, append that particular line to another file.
How can I achieve this?
I tried awk, but since some of the line descriptions have spaces, $4 is not always lag column.

So here is what I have, I use AWK to match $1 and $2 as 1 string in file1 to $1 and $2 as 1 string in file2. Now I'm wondering if I can extend this AWK command to incorporate the following:

I cannot seem to get what should be a simple awk one-liner to work correctly and cannot figure out why. I would like to use patterns from a specific field in one file as regex to search for matching strings in the entire line ($0) of another file.
I would like to output the lines of File2 which... (1 Reply)

rtc
rtc(1M) System Administration Commands rtc(1M)NAME
rtc - provide all real-time clock and GMT-lag management
SYNOPSIS
/usr/sbin/rtc [-c] [-z zone-name]
DESCRIPTION
On x86 systems, the rtc command reconciles the difference in the way that time is established between UNIX and MS-DOS systems. UNIX systems
utilize Greenwich Mean Time (GMT), while MS-DOS systems utilize local time.
Without arguments, rtc displays the currently configured time zone string. The currently configured time zone string is based on what was
last recorded by rtc-z zone-name.
The rtc command is not normally run from a shell prompt; it is generally invoked by the system. Commands such as date(1) and rdate(1M),
which are used to set the time on a system, invoke /usr/sbin/rtc -c to ensure that daylight savings time (DST) is corrected for properly.
OPTIONS -c This option checks for DST and makes corrections if necessary. It is normally run once a day by a cron job.
If there is no RTC time zone or /etc/rtc_config file, this option will do nothing.
-z zone-name This option, which is normally run by the system at software installation time, is used to specify the time zone in which
the RTC is to be maintained. It updates the configuration file /etc/rtc_config with the name of the specified zone and the
current GMT lag for that zone. If there is an existing rtc_config file, this command will update it. If not, this command
will create it.
FILES
/etc/rtc_config The data file used to record the time zone and GMT lag. This file is completely managed by /usr/sbin/rtc, and it is
read by the kernel.
