How does Bash pipe large amounts of data? - Unix & Linux How big is the pipe bufferUnix Linux Stack Exchange

The PIPE_SIZE depends on the page size. In 2.4 kernel, it was equivalent to size of one page (4KB). However versions after 2.6 are mapped to an array of 16 pages (64KB). This is defined in the file pipe_fs_i.h as PIPE_BUFFERS (16). How many system pages does Linux use?How many system pages does Linux use?The code ( include/linux/pipe_fs_i.h, and fs/pipe.c) seems to use 16 system pages (i.e. 64 KiB if a system page is 4 KiB), but the buffer for each pipe can be adjusted via a fcntl on the pipe (up to a maximum capacity which defaults to 1048576 bytes, but can be changed via /proc/sys/fs/pipe-max-size )).How big is the pipe buffer? - Unix & Linux Stack Exchange
