Is there a limit on the number on named pipes that can be created on a Linux machine?

  • 772

And if so, how do we increase it - the named pipes are created using mkfifo command -

named-pipes

  1. Since everything in linux is a file and fifi named pipes are files, i think there's no maximum number of named pipes ...

    However it depend if you want to create a huge number of named pipes in the same directory could be a limit that that is a constraint of some File system ...

  2. Each end of the pipe uses a file descriptor. On your system check out /proc/sys/fs/file-max.
