Add a big buffer to a pipe between two commands

Question

Given a bash command line of the form

commandA | commandB

I want to add a buffer of size ~1MB that sits between commandA and <

Answer 1

You can use

• buffer (mentioned)
• mbuffer (works on solaris too, possibly other UNIXes)

E.g.

    process1 | mbuffer -m 1024M | process2

to use a 1G buffer
