pipebuf is as a low‐overhead buffer for command pipelines.
pipebuf reads from standard input and writes to standard output, buffering the data it passes through. The buffer
capacity can be adjusted by providing the size as a command line argument. If no size is provided, it will default to
1048576 (1 MiB).
At least one of standard input or standard output is required to be a pipe.
This tool relies on the Linux‐specific splice(2) system call.
Since the pipes themselves serve as buffers, the capacity is limited by the system’s maximum pipe size as set in
/proc/sys/fs/pipe-max-size.
