List of all MySQL commands:
Note that all text commands must be first on line and end with ';'
? (\?) Synonym for `help'.
clear (\c) Clear command.
connect (\r) Reconnect to the server. Optional arguments are db and host.
delimiter (\d) Set query delimiter.
edit (\e) Edit command with $EDITOR.
ego (\G) Send command to mysql server, display result vertically.
exit (\q) Exit mysql. Same as quit.
go (\g) Send command to mysql server.
help (\h) Display this help.
nopager (\n) Disable pager, print to stdout.
notee (\t) Don't write into outfile.
pager (\P) Set PAGER [to_pager]. Print the query results via PAGER.
print (\p) Print current command.
prompt (\R) Change your mysql prompt.
quit (\q) Quit mysql.
rehash (\#) Rebuild completion hash.
source (\.) Execute a SQL script file. Takes a file name as an argument.
status (\s) Get status information from the server.
system (\!) Execute a system shell command.
tee (\T) Set outfile [to_outfile]. Append everything into given outfile.
use (\u) Use another database. Takes database name as argument.

--很明显修改pager参数就可以实现。
我执行如下：
mysql> pager vim
mysql> select * from cdef;
--不行。修改如下：
mysql> pager vim -
mysql> select * from cdef;
--ok通过！很明显这个结果仅仅read only。这样设置vim只读
mysql> pager vim -R -c "set nowrap" -
--可惜oracle没有这个特性。如果要永久有效，加入/etc/my.cnf文件中加入如下：
[mysql]
pager=vim -R -c "set nowrap syntax=txt" -
--google 查询mysql pager 还可以发现许多有趣的例子。
