Why in the Wide World of Sports do people do stuff like that?
./fred < textfile
No pipe, no extra process, no fuss.
_I_ often find myself backing up and changing the cat to a grep.
Also, "cat textfile" can be used to represent a generic data source.
Imagine this function
function datasource ()
{
cat textfile
}then it could be used as datasource | ./fred
The function datasource could be replaced (see the dhcp client scripts for an example where one might choose to do this) to obtain the data from another source - and SQL database as I've been doing recently, or to do some more complicated preprocessing of the data.
