SQL - how to alter info of a cell in table

Hello,
I am newbie on mysql and trying to edit my database from terminal under linux.
What I need to do is to change the information written in a cell in table.
Let me explain what I tried:

Code:

$ mysql -u mysqluser -p
$ show databases;
$ USE catalogue;
$ show tables ;
$ select * from phonebook;

it shows something like this:

+-------------+------------+--------+
| id | friend_name | age |
+-------------+------------+--------+
| 1 | Jaxier | 18 |
| 2 | Johanna | 26 |
| 3 | Johny | 25 |
| 4 | Lacatus | 18 |
| 5 | Julia | 25 |
+-------------+------------+---------+

What I want to do is to set age of Lacatus from 18 to 58

I tried below commands:

1)

Code:

$ update phonebook set id 4 SET age 58;

gives syntax error.

2)

Code:

$  ALTER phonebook ALTER id ALTER 4 SET age 58;

I 'd appreciate if you could explain what I should run in terminal

Thanks in advance
Boris

DBS_DUMPTABDATA(1p)					User Contributed Perl Documentation				       DBS_DUMPTABDATA(1p)

NAME

       dbs_dumptabdata - Creates file set with SQL table data

DESCRIPTION

       dbs_dumptabdata is an utility to create a file set with SQL table data.	For each table in the database dbs_dumptabdata calls the appropri-
       ate dumper utility with the output directed to a file named table.sql in the current directory. dbs_dumptabdata asks for a password if nec-
       essary.

COMMAND LINE PARAMETERS

       Required command line parameters are the DBI driver ("Pg" for Postgres or "mysql" for MySQL) and the database name. The third parameter is
       optionally and specifies the database user and/or the host where the database resides ("racke", "racke@linuxia.de" or "@linuxia.de").

COMMAND LINE OPTIONS

       -t TABLE[,TABLE,...], --tables=TABLE[,TABLE,...]

       Comma-separated list of tables to dump.

       --exclude-matching-tables=REGEXP

       Excludes any table matching the regular expression REGEXP from dumping.

       --use-printtab

       Uses generic dump (similar to "dbs_printtab") instead of the dumper utility provided by the DBMS.

BUGS

       msql is not supported.
