grabbing just a bit of a line of text

[maddave]

I have a file with one line in it. The line says:

"spcc123.dbf"

How can I just extract the number of this line?

I want to string out this line and just read from the 5th character to the charater before the full stop. I cant work out whats the best way to do it.

Hi

tr -dc '[:digit:]' < /input/file

Just my 2 cents:
tr -dc '[:digit:]\n' < /input/file

Hope This Helps, PH.

Burrrrrilliant! Many thanks. I was looking at the tr function in my manual, but it helpfully only includes a few of the options so didn't think there was anymore to it than just replacing characters.

Thanks.

Tip: man tr
