Based on a few assumptions on the structure of your input file, like
- the numerical "detection type" is introduced by the string cn2=, up to four digits, and terminated by a space char.
- there's no more than one time stamp per line, introduced by the partial string rt=, 10 digits long
here's an awk proposal, working on a mock up input file, that might satisfy your request:
Hi,
One silly question. I would like to add statement like below and append to a file. I used the below code; however, it does not work. Can anyone please tell me what mistakes I have made?
awk '
{ for (i=1;i<=563;i++)
print i
}'>>output.txt
Thanks.

ive input file contains to clums a and b spreated by pipe
a | b
123|456
323|455
and
xyz contains other info about a and b
now i want to print as follows:
a | b | "info from xyz"
but "info from xyz" might be more than 1 line and i want to keep the format to 3 cloums.

I have a forloop which checks a log for a set of 6 static IP addresses and each IP found is logged to a file which is then mailed to me.
After the forloop I always have a text file that may contain up to 6 IP addresses or may contain 0.
What I want to do is substitute the IP addresses (if any)... (2 Replies)

sd_journal_get_cutoff_monotonic_usec
SD_JOURNAL_GET_CUTOFF_REALTIME_USEC(3) sd_journal_get_cutoff_realtime_usec SD_JOURNAL_GET_CUTOFF_REALTIME_USEC(3)NAME
sd_journal_get_cutoff_realtime_usec, sd_journal_get_cutoff_monotonic_usec - Read cut-off timestamps from the current journal entry
SYNOPSIS
#include <systemd/sd-journal.h>
int sd_journal_get_cutoff_realtime_usec(sd_journal* j, uint64_t* from, uint64_t* to);
int sd_journal_get_cutoff_monotonic_usec(sd_journal* j, sd_id128_t boot_id, uint64_t* from, uint64_t* to);
DESCRIPTION
sd_journal_get_cutoff_realtime_usec() gets the realtime (wallclock) timestamps of the first and last entries accessible in the journal. It
takes three arguments: the journal context object and two pointers to 64-bit unsigned integers to store the timestamps in. The timestamps
are in microseconds since the epoch, i.e. CLOCK_REALTIME. Either one of the two timestamp arguments may be passed as NULL in case the
timestamp is not needed, but not both.
sd_journal_get_cutoff_monotonic_usec() gets the monotonic timestamps of the first and last entries accessible in the journal. It takes
three arguments: the journal context object, a 128-bit identifier for the boot, and two pointers to 64-bit unsigned integers to store the
timestamps. The timestamps are in microseconds since boot-up of the specific boot, i.e. CLOCK_MONOTONIC. Since the monotonic clock begins
new with every reboot it only defines a well-defined point in time when used together with an identifier identifying the boot, see
sd_id128_get_boot(3) for more information. The function will return the timestamps for the boot identified by the passed boot ID. Either
one of the two timestamp arguments may be passed as NULL in case the timestamp is not needed, but not both.
RETURN VALUE
sd_journal_get_cutoff_realtime_usec() and sd_journal_get_cutoff_monotonic_usec() return 1 on success, 0 if not suitable entries are in the
journal or a negative errno-style error code.
NOTES
The sd_journal_get_cutoff_realtime_usec() and sd_journal_get_cutoff_monotonic_usec() interfaces are available as a shared library, which
can be compiled and linked to with the libsystemd-journal pkg-config(1) file.
