![]() It can also be configured to index binary formats (PDF, DOC, DOCX, etc) if you provide supported command line converters. Periodically updating the db via a crontab entry that runs omindex. The steps for configuring xapian search for macos are listed here (should be easy to adapt to other OS's). Omega is originally meant to be used for website search but can be repurposed for 'desktop search'. On the next level, after extensive searching for a granular desktop search solution with a friendly web UI specifically for searching in tens of thousands of HTML files, have finally settled on omega-xapian - a fast and minimalist indexed search engine which comes with a cgi script that can be run on a webserver (used via caddy with the cgi plugin). The accepted answer fits well the core original requirement. Returns the starting index of the substring of the string expr that matches the regular expression specified by the pattern pat, 0 if there is no match. In bash, Im reading a string from a file that looks like the following: 'network': 'Purple', How would I use grep, awk or even sed to pull out just the string: 'Purple&qu. I am not interested in system-level indexing apps like spotlight on mac or their linux counterparts, since I am looking for something granular at file or subfolder level. I am considering whoosh as an option but that would require extra coding. I would like to know if there is some 'cheap' way to create an index and search against it. In the following example, the string kangaroo will match only if it occurs at the very end of a line. We will search for Phoenix in the current directory, show two lines before and after the matches along with their line numbers. Append the -n operator to any grep command to show the line numbers. ![]() In contrast with, specifies patterns that will be matched if the line ends with the string before. Example: grep I grep.txt -n Result: 2: I 2. BareGrepPro has all the features of BareGrep plus. When grep prints results with many matches, it comes handy to see the line numbers. This pattern means that the grep will match the strings whose lines begin with the string specified after. BareGrep Icon Product Overview Command Line Use Regex Reference Export Reference FAQ User Comments. grep 'kangaroo' file.txt Use the (dollar) symbol to match expression at the end of a line. To Display Line Numbers with grep Matches. So far the only 'faster-than-grep' solution which I've found is fgrep constrained to ANSI rather than UTF-8 (from ) - while it provides an impressive speedup, it is still too slow for large files. In the following example, the string kangaroo will match only if it occurs at the very beginning of a line. I'm looking for a simple console utility that would work similar to locate/slocate/mlocate but instead of file names would index file contents with specific mime types in a configurable location. I don't necessarily need support for regular expressions, although case insensitivity would be good to have. Is there a way to index a file or a file tree from the console so that searching for substrings can be done faster than plain grepping?
