pranabrana · #1 (**permalink**) 06-30-2009

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:

Code:

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

Update I had assumed the tr bits were working but they aren't...

Here is something that works:

Code:

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

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

Not if you do what I did:

Code:

grep "^apache$"

Which is looking for apache with a start of line at the beginning and an end of line at the end!
