Count specific character(s) very large file
I'm trying to count the number of 2 specific characters in a very large file. I'd like to avoid using gsub because its taking too long.
I was thinking something like:
awk '-F[X,Y]' { t += NF - 1 } END {print t}' infile > outfile
which isn't working
Any ideas would be great.

NAME
timetrans - Converts time into time
SYNOPSIS
timetrans [units-options] [-count]
DESCRIPTION
timetrans converts time from one type of unit to another. If any of the units options are specified, then timetrans will convert those
time units into the number of seconds to which they add up. If given the count option, timetrans will convert that number of seconds into
the appropriate number of weeks, days, hours, minutes, and seconds. The converted result is printed out. Units options cannot be
specified in the same execution as the count option, and vice versa.
timetrans is intended for use with DNSSEC-Tools, for calculating a zone's expiration time.
OPTIONS
Units Options
The converted value of each unit is totaled and a single result printed.
-seconds seconds

-minutes minutes

-hours hours

-days days

-weeks weeks

Count Option
