In a file I have to count a particular word. like i need apache how many times.

I tried this

$ tr "\011" "\012\012"<foo1 | tr -cd "[a-zA-z\012]" |sort\uniq -c


but I got result like this

32 apache
18 dns
12 doctor


Please sugest me

If all you want is the count for apache then you could do:

$ tr "\011" "\012\012"<foo1 | tr -cd "[a-zA-z\012]" | grep "^apache$" | wc -l

$ tr "\011\040" "\012\012"<foo1 | grep -ic "^apache$"

Thanks !!! any simpler way ?

Is 'apache' the same as 'apaches' and the same as apache's or 'apache,'?

Not if you do what I did:

grep "^apache$"
