more help,
HI guys, im revising for an exam if anyone is wondering, I typed the following
grep King MagnaCarta.txt
echo grep King MagnaCarta.txt
`echo grep King MagnaCarta.txt`
the first one gets me the sentence in which King is mentioned
second one just prints out grep King MagnaCarta.txt
the third one displays a msg saying
echo grep King MagnaCarta.txt: Command not found
Why does it do that? What do the single quotes change in the code??
