Thanks for the response, that's done the trick. Can't believe it was staring me in the face all that time!
I was building the search string to create the same command I would if I was manually issuing it. I always use
I believe the brackets are superfluous but I guess it's a habit. I guess I could also have done -e but then I'd still of had my whitespace issue.
As you have noticed, I am actually looking for a literal = character in front of my search string, that is intentional.
The script is designed so that I will pass in arguments specifying the search string, start and end times and search for all occurrences within that time frame. There is more to the script obviously, but I just pasted the relevant part.
I'd like to grep a pattern of a version number as
*_number.number.number
number should be digit
my grep is
|egrep '^*++\.+'
It works for V_3.2.1 or V _5.3.2 but not with V_43.6.543 !!!!!
How can I specify any repetition of digit in the ?
thanks, (4 Replies)

nngrab
NNGRAB(1) General Commands Manual NNGRAB(1)NAME
nngrab - news retrieval by keyword (nn)
SYNOPSIS
nngrab [ -c ] keyword
DESCRIPTION
nngrab invokes nn on all USENET articles whose subject (or keyword) field(s) contain an instance of keyword. nngrab is a fast equivalent
for:
nn -mxX -s/keyword all
For example,
nngrab tesla
will retrieve items concerning Nikola Tesla.
Keyword case is ignored unless -c is specified, and the keyword can be a regular expressions (escaped to avoid conflicts with the shell).
For example,
nngrab "n.*tesla"
The range of search includes all newsgroups on the system, including ones which are unsubscribed.
FILES
$db/subjects subject database
SEE ALSO nn(1), nnspew(8), egrep(1)NOTES
nngrab can be much faster than the equivalent command shown above, if the tertiary news subject database generated by the nnspew(8) daemon
exists. To enable the faster operation, nnspew must be executed regularly by cron.
nngrab uses egrep(1) to scan the subject database, so if you are not running fast egrep (GNU-style) this is all for naught.
nngrab will use a subject database generated by nnspew independent of its age. Thus, if you stop running nnspew, remember to remove the
subjects file as well.
BUGS
Under version 6.4 onwards, search of the "Keywords:" field is not supported.
Search on name is not possible either.
