|

| 16 | The find program searches for files in a directory hierarchy which match
|
|---|
| 17 | a certain criteria. If no criteria is given, it lists all files in the
|
|---|
| 18 | current directory and it's subdirectories.

|

| 26 | Locate scans a database which contain all files and directories on a
|
|---|
| 27 | filesystem. This program lists the files and directories in this
|
|---|
| 28 | database matching a certain criteria. If a user is looking for a file this
|
|---|
| 29 | program will scan the database and tell him exactly where the files he
|
|---|
| 30 | requested are located. This only makes sense if the locate database is
|
|---|
| 31 | fairly up-to-date else it will provide out-of-date information.

|

| 38 | <para>
|
|---|
| 39 | The updatedb program updates the locate database. It scans the entire
|
|---|
| 40 | file system (including other file system that are currently mounted
|
|---|
| 41 | unless it is told not to do so) and puts every directory and file it finds
|
|---|
| 42 | into the database that's used by the locate program which retrieves this
|
|---|
| 43 | information. It's a good practice to update this database once a day to
|
|---|
| 44 | have it up-to-date whenever it is needed.

| 51 | <para>
|
|---|
| 52 | The xargs command applies a command to a list of files. If there is a need to
|
|---|
| 53 | perform the same command on multiple files, a file can be created that
|
|---|
| 54 | contains all these files (one per line) and use xargs to perform that
|
|---|
| 55 | command on the list.

|
|---|
| 63 | updatedb runs a program called frcode to compress the list of file names
|
|---|
| 64 | using front-compression, which reduces the database size by a factor of
|
|---|
| 65 | 4 to 5.
