| [b822811] | 13 | <para>The find program searches for files in a directory hierarchy which match
|
|---|
| [6370fa6] | 14 | a certain criteria. If no criteria is given, it lists all files in the
|
|---|
| [b822811] | 15 | current directory and it's subdirectories.</para>

| [b822811] | 21 | <para>Locate scans a database which contain all files and directories on a
|
|---|
| [6370fa6] | 22 | filesystem. This program lists the files and directories in this
|
|---|
| [3cc70a0] | 23 | database matching a certain criteria. If a user is looking for a file this
|
|---|
| 24 | program will scan the database and tell him exactly where the files he
|
|---|
| 25 | requested are located. This only makes sense if the locate database is
|
|---|
| [b822811] | 26 | fairly up-to-date else it will provide out-of-date information.</para>

| [b822811] | 32 | <para>The updatedb program updates the locate database. It scans the entire
|
|---|
| [6370fa6] | 33 | file system (including other file system that are currently mounted
|
|---|
| [3cc70a0] | 34 | unless it is told not to do so) and puts every directory and file it finds
|
|---|
| [6370fa6] | 35 | into the database that's used by the locate program which retrieves this
|
|---|
| [3cc70a0] | 36 | information. It's a good practice to update this database once a day to
|
|---|
| [b822811] | 37 | have it up-to-date whenever it is needed.</para>

| [b822811] | 43 | <para>The xargs command applies a command to a list of files. If there is
|
|---|
| 44 | a need to perform the same command on multiple files, a file can be created
|
|---|
| 45 | that contains all these files (one per line) and use xargs to perform that
|
|---|
| 46 | command on the list.</para>

|

| [b822811] | 52 | <para>updatedb runs a program called frcode to compress the list of file names
|
|---|
| [eb9c756] | 53 | using front-compression, which reduces the database size by a factor of
|
|---|
| [b822811] | 54 | 4 to 5.</para>
