grep only word matching the pattern
Hi gurus,
A file contains many words in format "ABC.XXXX.XXXX.X.GET.LOG" (X->varying). Now my shell script want this list (only words in formatABC.XXXX.XXXX.X.GET.LOG ) to continue the process. Pls help me.

Thanks,
Poova.

Code:
nawk '
{
    for (o=1;o<=NF;o++){
        if ($o ~ /^ABC.*GET.LOG$/){
            print $o
        }
    }
}' file

use -o option in grep.

Code:
grep -o "ABC\.....\.....\..\.GET\.LOG" filename
