#Mac sierra search for files containing update
When you update the mlocate database, it keeps timestamp information in the database. It indexes the entire file system, but the search results only include files to which the current user has access. The mlocate command is a new implementation of locate. In the above example, the backslash disables the implicit replacement of “mydata” by “*mydata*” so you end up with only results containing “mydata.” The most common wildcard symbols are the question mark ( ? ), which stands for a single character and the asterisk ( * ), which stands for a contiguous string of characters. A wildcard is a symbol that can be replaced by one or more characters when the expression is evaluated. The backslash in the above command is a globbing character, which provides a way of expanding wildcard characters in a non-specific file name into a set of specific filenames. If you want to find all files or directories that contain exactly and only your search criteria, use the -b option with the locate command, as follows. locate mydataįor example, the above command found two files containing “mydata” and one file containing “data.” The basic form of the locate command finds all the files on the file system, starting at the root, that contain all or any part of the search criteria. To do this, type the following command at the prompt: sudo updatedb The database is updated periodically from cron, but you can also update it yourself at any time so you can obtain up-to-the-minute results. The locate command returns a list of all path names containing the specified group of characters. The locate command is faster than the find command because it uses a previously built database, whereas the find command searches in the real system, through all the actual directories and files. For more information about the find command, run man find in a Terminal window and press Enter. The find command has a lot of options available for refining the search. If find doesn’t locate any files matching your criteria, it produces no output.
It is the case insensitive version of the -name command. If you want the search for a word or phrase to be case insensitive, use the -iname option with the find command. NOTE: The find command defaults to being case sensitive. All files in the current directory starting with “pro” are listed.
