[LCP]Char Comparisons?

[Rokicki, Andrew]

if(buf=="load")  I don't think you want to do this.

look up:
man string
or
man 3 strings

You need to do string opperation here.
what you are doing you are comparing pointer to "load" which will be false.
you could do 
if (buff[0]=='l') 
this with comapare first character.
