FYI. If you happen to have a file with out an EOL (newline) as the last line of the file, it is not included as part of the count. The awk command will include the last line regardless of terminator.

Hi,
Is it possible to find the total number of records processed by awk at begining.
NR gives the value at the end. Is there any variable available to find the value at the begining?
Thanks

NAME
mt - magnetic tape manipulating program
SYNOPSIS
tapename] command [count]
Obsolescent
tapename] command [count]
DESCRIPTION
is used to give commands to the tape drive. If tapename is not specified, the environment variable is used; if is not defined, the default
drive is used.
winds the tape in the requested direction (forward or backward), stopping after the specified count EOF marks or records are passed. If
count is not specified, one is assumed. Each EOF mark counts as one record. When winding backwards, the tape always stops at the BOT
marker, regardless of the number remaining in count.
accepts the following commands:
Write count EOF marks.
Forward space
count files.
Forward space
count records.
Backward space
count files.
Backward space
count records.
Rewind tape.
Rewind tape and go offline.
Seek to end of data (DDS and QIC drives only).
Write count setmarks (DDS drives only).
Forward space
count setmarks (DDS drives only).
Backward space
count setmarks (DDS drives only).
Print status information about the tape drive.
Reserve tape drive for sole use by the host issuing the
command (stape or estape driver only).
Release tape drive from sole use by the host issuing the
command (stape or estape driver only).
Spacing operations (back or forward space file or record) leave the tape positioned past the object being spaced to in the direction of
motion. That is, backspacing a file leaves the the tape positioned before the file mark, forward spacing a file leaves the tape positioned
after the file mark. This is consistent with all classical usage on tapes.
WARNINGS
Only raw, no-rewind Berkeley-type devices should be specified. This type of device will not reposition the tape upon close. An example of
such a device is or See mt(7) for more details.
It is possible to wind the tape beyond the EOT marker and off the end of the reel.
A reservation may only be cleared with a release by the host that issued the original reserve. In the event that the host that holds the
reservation is no longer available, the command may be used to reclaim the device by issuing a bus device reset. See st(1M) for more
details.
The reserve/release functionality can only be issued to drives using the or driver.
EXAMPLES
Rewind the tape associated with the device file or (if legacy DSF is disabled):
