locate
Sends a query to the database of file names to quickly find files
based on the user’s input. The database is built by the
updatedb
command and typically stores the location of files
within the system, making it faster to search for them compared to using
traditional search tools.
Relevant Commands:
Command | Description |
---|---|
locate <filename> |
Searches for files in the database that match the given filename pattern. |
locate -i <pattern> |
Searches for files case-insensitively that match the given pattern. |
locate -r <regex> |
Searches for files using a regular expression (regex). |
locate -c |
Displays the count of matching files, rather than listing them. |
locate -n <number> |
Limits the number of results displayed to the specified number. |
updatedb
Updates the database used by the locate
command. It
scans the file system and stores file paths and related information in a
database, allowing locate
to perform quick searches without
having to access the file system repeatedly. The database is typically
updated periodically by system tools or via scheduled tasks.

update (e.g., nfs , tmpfs ). |
