problem with wget COMMAND
 

I have to download directories from a site as
let the url :

http://www.mysite.com/this/that/what/peter
now, in the peter directory, there are a number of directories starting with the letter a to z and A to Z. eg, abc, add, axl, ptr, pm, phonet, phiew, din, ten tenn.

Now I want to download all the directories in the peter directory that starts with a letter say a or A. Then how to give the command wget to do the above task???

Try curl:

man curl

It does what you want.

Try using the -I "A*,a*" option.
