|
|---|
| 10 | <para>bigram is used together with code to produce older-style locate
|
|---|
| 11 | databases. To learn more about these last three programs, read the locatedb.5
|

| 15 | <para>code is the ancestor of frcode. It was used in older-style locate

|
|---|
| 19 | <para>The find program searches for files in a directory hierarchy which match
|
|---|
| 20 | a certain criteria. If no criteria is given, it lists all files in the
|
|---|
| 21 | current directory and its subdirectories.</para></sect4>

|
|---|
| 24 | <para>frcode is called by updatedb to compress the list of file names
|
|---|
| 25 | using front-compression, which reduces the database size by a factor of
|
|---|
| 26 | 4 to 5.</para></sect4>

| 28 | <sect4><title>locate</title>
|
|---|
| 29 | <para>locate scans a database which contains all files and directories on a
|
|---|
| 30 | filesystem. This program lists the files and directories in this
|
|---|
| 31 | database matching a certain criteria. If a user is looking for a file this
|
|---|
| 32 | program will scan the database and tell him exactly where the files he
|
|---|
| 33 | requested are located. This only makes sense if the locate database is
|
|---|
| 34 | fairly up-to-date, else it will provide out-of-date information.</para></sect4>

|

| 36 | <sect4><title>updatedb</title>
|
|---|
| 37 | <para>The updatedb program updates the locate database. It scans the entire
|
|---|
| 38 | file system (including other file systems that are currently mounted
|
|---|
| 39 | unless it is told not to do so) and puts every directory and file it finds
|
|---|
| 40 | into the database that's used by the locate program, which retrieves this
|
|---|
| 41 | information. It's good practice to update this database once a day to
|
|---|
| 42 | have it up-to-date whenever it is needed.</para></sect4>

|
|---|
| 45 | <para>The xargs command applies a command to a list of files. If there is
|
|---|
| 46 | a need to perform the same command on multiple files, a list can be created
|
|---|
| 47 | that names all those files (one per line) and xargs can perform that
|
|---|
| 48 | command on those files.</para></sect4>
