Shell Programming and Scripting

Hi all,
Can someone help me with the following problem.
I am executing the following command:
(search for occurences of 'error' in files that match cl-*.log expression)
> grep -cw -i --max-count=1 'error' cl-*.log
this command outputs:
cl-apache.log:1
cl-apache_error.log:1
cl-apache_warn.log:1
cl-apache_2009_05_13.log:1

Than I want to filter the results from this command and exclude lines
that are matching some user entered wildcard (lets say: exclude files
from the result that match 'cf-*err*'). So I tried the following command:
> grep -cw -i --max-count=1 'error' cl-*.log | grep -v 'cf-*err*'

I was expecting that the second command (grep -v 'cf-*err*') will
filter the first command OUTPUT, but instead, it saerch 'cf-*err*'
WITHIN each file Content, instead of fcommand output.

Any help is appretiated,
Thx

The second grep can't be filtering on the basis of file contents because the ouyput you have given does not include any content or am i missing something?

I would do something like:

$ grep -wl error cl-*.log | grep -v error

The grep -wl will output the names of the files containing "error", but not errors (for instance) so then the "grep -v" removes filenames containg "error". is that what you are after?

Yes, That's prety much what I was looking for.
Thanx for the quick reply, I appretiate.

That is what it does. Since the search pattern doesn't exist in the output of the first command, the output will be the same as that of the first command. If it's not, you are not posting the command that you actually ran.

It could not do that; you didn't put any filenames on the command line, only a search pattern. Therefore, it can only search its standard input.
