Answer / rajib mallick
In Unix, A filter is nothing but the commands/ Programs
that have the capability to read its input from std/in, and
gives the output to std/out.Fork and exec are resposible
system calls for the development of filters.
By ex:- cut, sort, tee, touch, lp, more, less, head, tail
etc...
