Usage: ${0##*/} [FOLDERS]
|
|
|
|
Update the 'locate' databases for the home folder, external drives and the
|
|
FOLDERS arguments.
|
|
|
|
For folders other than home, databases are only updated if found, they are not
|
|
automatically created (unless explicitly specified in the FOLDERS arguments).
|
|
|
|
- The database for the home folder is stored in '$HOME_DB_FOLDER/$DB_FILE'.
|
|
- Other databases are stored in '$DB_FILE' at the target root.
