For instance, I do a grep on files that have tiger woods listed as golfer number 1 and copy these files to a specified directory.
Possible usage:
mygrep “tigerWoods” | grep golfer1| test
(where test) is my directory

I have a server where many people run different programs. Currently the CPU is almost idle, but the machine is doing lots of I/O (as reported by vmstat), and anything that needs I/O (disk) runs terribly slow.
Is there any easy way to find out for sure which process is doing the I/O ?

I know in perl you just put .pl (filename.pl) at the end of the file you named, and to run the that you just type perl filename.pl.
In unix I being told its something like #!/bin/sh? Where does this go? Does this mean I make the file with #!/bin/sh in front of the file names like #!/bin/sh/filename?

I’m using curl to do some testing of http POSTs and GETs (not webpages, but a sort of programming interface).
curl expects parameters passed with the -d switch to be url encoded; for example
curl \
http://myTestSite/process \
-d title=”The%20Big%20Red%20One”
I’d like to do something like this in a Bash script:
curl \
http://myTestSite/process \
-d title=${urlencode(”The Big Red One”)}
Is there a standard urlencode utility available on a Linux box?
