hi,

i'm having problem like this.
i wish to grep some keyword from certain files in one directory.

let's say i have a lot of files in my directory with the name of file.1 file.2 file.3 ...... file.500
i only wish to grep the keyword from file.20, file.21, file.23 .... file.50

i tried the following command:
----------------------------
grep 'keyword' file.[20-50]
----------------------------

i used the command above and it returns no value.
i found that [20-50] is not the appropriate way to specify file.
anyone can guide me to this problem?

how about

thanks
that works but i want only file 20-50
?? will include 51-99, 10-19

try

The problem with that is that it would pick up everything from 20 to 59. For 20 to 50, try something like:

i see !!!!
thanks for the help! have been figuring out for a long time!
