NAME¶
writebuffer - write output to devices which don't like constant stopping and
starting
SYNOPSIS¶
writebuffer [
--mlock] [
size]
DESCRIPTION¶
writebuffer reads data on standard input and writes it to standard
output. It will buffer internally up to
size megabytes and will only
write data when the buffer is at least 75% full or when there is no more input
to fill the buffer.
size may also be suffixed with
m,
k, or
b to
indicate that it is in megabytes (2^20), kilobytes (2^10) or bytes.
It is intended for use in situations where many small writes are undesirable for
performance reasons, e.g. tape drives.
OPTIONS¶
- --mlock
- Calls mlock(2) to lock the buffer into memory.
