This manual page documents the GNU version of locate. For each given pattern, locate searches one or more databases of file names and displays the file names that contain the pattern. Patterns can contain shell-style metacharacters: `*', `?', and `[?'. The metacharacters do not treat `/' or `.' specially. Therefore, a pattern `foo*bar' can match a file name that contains `foo3/bar', and a pattern `*duck*' can match a file name that contains `lake/.ducky'. Patterns that contain metacharacters should be quoted to protect them from expansion by the shell.
If a pattern is a plain string -- it contains no metacharacters -- locate displays all file names in the database that contain that string anywhere. If a pattern does contain metacharacters, locate only displays file names that match the pattern exactly. As a result, patterns that contain metacharacters should usually begin with a `*', and will most often end with one as well. The exceptions are patterns that are intended to explicitly match the beginning or end of a file name.
-d path, --database=path
Instead of searching the default file name database, search the file name databases in path, which is a colon-separated list of database file names. You can also use the environment variable LOCATE_PATH to set the list of database files to search. The option overrides the environment variable if both are used.
The file name database format changed starting with GNU find and locate version 4.0 to allow machines with diffent byte orderings to share the databases. This version of locate can automatically recognize and read databases produced for older versions of GNU locate or Unix versions of locate or find.
Only print out such names that currently exist (instead of such names that existed when the database was created). Note that this may slow down the program a lot, if there are many matches in the database.
Ignore case distinctions in both the pattern and the file names.
Print a summary of the options to locate and exit.
