OT: grep and regex patterns

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all,

There is a file with a collection of links from global sites. While trying to sort the links into categories I'm catching the wrong things.

e.g. find links from India:

PATTERN="^.*http:\/\/.*\.in.*$"
grep $PATTERN < file.of.links >links.in

Even though the "." in front of "in" is escaped with "\" PATTERN is catching any text containing "in". This is obviously not what is intended.

Any one out there point me to the error of my ways?

TIA,
Mike Wright
