Re: [LI] comparing - and --

["Harsha Yalagach" <hyalagach@xxxxxxxxxxx>]

hello
     in linux if u want to give a single alphabet option then u give  the 
'-', but if u want to give an option that is more than one character long 
then we use '--'

as in

      ls -a - --color |more
or
      ls -al --color |more

u can even concatenate to single character options in to a single string. 
thats where it helps us to differentiate with single character & string 
options

Bye
Harsha
