I created a file1.txt with 500,000 keys and did some timing tests on my laptop (2.6GHz i3 M 350): awk takes about 1.08 secs to check a zip record against the 500K keys. I loaded the keys into a linked list in C and did a substring match an this took 0.842 secs per zip record (so with a custom C program you might expect a 15%-20% imporvement in speed).
The real issue here is the substring match of each key, if you could determine the key of a zip datafile record and do and database or B-tree lookup in would only take a few miliseconds per zip datafile record. For example if you could say the key for data record:
Was "56456456546" and indexed search could be done against your 500K keys and the matching key ticked off as found very quickly. Without this ability you are could really only expect to check in the order of 10 ziprecords per second.
I have one file:
123*100*abcd*10
123*101*abcd*-29*def
123*100*abcd*-10
123*102*abcd*-105*asd
I would like to parameterize the search patterns in the following way so that the user could dynamically change the search pattern.
*100* and *- (ie *minus)
*102* and *-
The output that is... (6 Replies)
Hi
I'm not very good with the serach patterns and I'd need a sample how to find a line that has multiple patterns.
Say I want to find a line that has "abd", "123" and "QWERTY" and there can be any characters or numbers between the serach patterns, I have a file that has thousands of lines and... (10 Replies)

httpindex
httpindex(1) General Commands Manual httpindex(1)NAME
httpindex - HTTP front-end for SWISH++ indexer
SYNOPSIS
wget [ options ] URL... 2>&1 | httpindex [ options ]
DESCRIPTION
httpindex is a front-end for index++(1) to index files copied from remote servers using wget(1). The files (in a copy of the remote direc-
tory structure) can be kept, deleted, or replaced with their descriptions after indexing.
OPTIONS
wget Options
The wget(1) options that are required are: -A, -nv, -r, and -x; the ones that are highly recommended are: -l, -nh, -t, and -w. (See the
EXAMPLE.)
httpindex Options
httpindex accepts the same short options as index++(1) except for -H, -I, -l, -r, -S, and -V.
The following options are unique to httpindex:
-d Replace the text of local copies of retrieved files with their descriptions after they have been indexed. This is useful to display
file descriptions in search results without having to have complete copies of the remote files thus saving filesystem space. (See
the extract_description() function in WWW(3) for details about how descriptions are extracted.)
-D Delete the local copies of retrieved files after they have been indexed. This prevents your local filesystem from filling up with
copies of remote files.
EXAMPLE
To index all HTML and text files on a remote web server keeping descriptions locally:
wget -A html,txt -linf -t2 -rxnv -nh -w2 http://www.foo.com 2>&1 |
httpindex -d -e'html:*.html,text:*.txt'
Note that you need to redirect wget(1)'s output from standard error to standard output in order to pipe it to httpindex.
EXIT STATUS
Exits with a value of zero only if indexing completed sucessfully; non-zero otherwise.
CAVEATS
In addition to those for index++(1), httpindex does not correctly handle the use of multiple -e, -E, -m, or -M options (because the Perl
script uses the standard GetOpt::Std package for processing command-line options that doesn't). The last of any of those options ``wins.''
The work-around is to use multiple values for those options seperated by commas to a single one of those options. For example, if you want
to do:
httpindex -e'html:*.html' -e'text:*.txt'
do this instead:
httpindex -e'html:*.html,text:*.txt'
