Regular Expressions in K Shell Script
HTML Code:
I need to write a K shell script to find full file names , line numbers and lines which have words meeting either of following 2 criterias -
1)words which are 6 to 8 character long and alphanumeric.
2)Minimum 8 characters, one upper case, one lower case letter, one of the special characters within list (~,!,$,%,^,&,-,=,.,:,;)
I need create an o/p file like
file name - <>
matching line number - <>
matching line - <>
Struggling with regular expressions, but no luck yet. Appreciate your inputs.
Note - I need to start searching from root directpry, so the files to be searched would be very huge in number as well as volume.
O.S. is  Sun 5.10
