Subject: special vars
Hi all,
Can any one help me understand the usage of special variable $| ?
I know the description of this var. If set to nonzero, forces a flush after every write or print.
But I am not able to understand its importance.
If I am reading a file and writing the contents in a separat file after some processing. What will happen if I set $|=1 ?
Thanks, NP
if u use an OS like linux (which will not write things imediately to disc) this forces it to do so.
