Hi Forum
I have a tab delimited file that opens well in Openoffice calc (excel). But when I perform any operation in command line, it reads the file incorrectly. When I 'save As' the same file in office as tab delimited then it works fine.

I have a file which was pipe delimited, I need to make it tab delimited. I tried with sed but no use
cat file | sed 's/|//t/g'
The above command substituted "/t" not tab in the place of pipe.

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.
