# Description
The REBIULD-INDEX command will rebuild indexes on a jBase file.
rebuild-index -Options filename { {indexname {indexname ...}} | *}
Where Options can be:
| Option | Description |
|---|---|
| -a | Rebuilds ALL indexes in the file |
| -r | Rebuild ALL files in the directory specified |
| -v | Verbose mode, one period display for every 1000 records rebuilt |
This command will rebuild the index definitions. It can be used in the following circumstances:
- Following the corruption of the index file
- Following a file restore using jrestore . This is detailed later.
- Following the creation of an index using create-index.
By default create-index will build the index and will not require a rebuild-index command to be performed.
Option -a means you want to rebuild all the indexes defined for the file. This can also be achieved by specifying * as the index name. Otherwise you must specify on the command line one or more index names to rebuild.
Option -r will rebuild all files in the directory name specified. This is a useful operation after using, for example, jrestore to restore your database and then you can use the option -r to rebuild all files in a certain directory.
