Top Forums UNIX for Advanced & Expert Users Cannot find logical file format for BSD file headers. Post 302957141 by Chris_top_he_r on Wednesday 7th of October 2015 12:02:00 PM
Old 10-07-2015
Thanks Jim. I was thinking it might be as difficult as you say. When I've posted the complete situation over the past few days, I get responses that suggest I should not want to know this or do this. As an enthusiast I like to explore and learn, so thought I would try to ask a much more direct technical question to avoid being scolded. :-)

Attached are several of my posts from a more thorough thread I started last week that might answer any questions you have. Sorry it is so long.

I've had these similar data errors on a MacBook 2006 10.6.8, a MacBook 2010 10.8.x, and a two week old MacBook Pro 10.10.5. The older ones have been cleaned up with install of OS. Because of our hack history here I was trying to learn more about this.

udm_find - Perform search

SYNOPSIS
resource udm_find (resource $agent, string $query) DESCRIPTION
Performs a search. The search itself. The first argument - session, the next one - query itself. To find something just type words you want to find and press SUBMIT button. For example, "mysql odbc". You should not use quotes " in query, they are written here only to divide a query from other text. mnoGoSearch will find all documents that contain word "mysql" and/or word "odbc". Best documents having bigger weights will be dis- played first. If you use search mode ALL, search will return documents that contain both (or more) words you entered. In case you use mode ANY, the search will return list of documents that contain any of the words you entered. If you want more advanced results you may use query language. You should select "bool" match mode in the search from. PARAMETERS
o $agent - A link to Agent, received after call to udm_alloc_agent(3). o $query - mnoGoSearch understands the following boolean operators: & - logical AND. For example, "mysql & odbc". mnoGoSearch will find any URLs that contain both "mysql" and "odbc". | - logical OR. For example "mysql|odbc". mnoGoSearch will find any URLs, that contain word "mysql" or word "odbc". ~ - logical NOT. For example "mysql & ~odbc". mnoGoSearch will find URLs that contain word "mysql" and do not contain word "odbc" at the same time. Note that ~ just excludes given word from results. Query "~odbc" will find nothing! () - group command to compose more complex queries. For example "(mysql | msql) & ~postgres". Query language is simple and powerful at the same time. Just consider query as usual boolean expression. RETURN VALUES
Returns a result link identifier on success or FALSE on failure. PHP Documentation Group UDM_FIND(3)
