Hi,

I don't understand what is the correct way of writing:

egrep -l '{$min,$max} $pattern' $filename

I tryed to search on google how to wtrite {$min, $max}, but I don't have success

What task exactly are you trying to do? -- not how you think you should do it.

I'm trying to search in a list of files, the files that contain a pattern for a number of times between Min and Max

But I don't know how to do it

Another question about EGREP:

How can I pass a list of files to egrep?

I Tryed:

 find | egrep -l  abc 
 ls -lR | egrep -l  abc

but the shell says:
(standard input)

Why?

Hi,

I have to write a command (with egrep, awk or sed) to list the name of the files that contain a pattern that is between two values: min e max.
It also have to return the number of time the pattern has been found in every simgle files is listed.

I tryed to do it with egrep, but I have no success.

Do you have any advice?
