Linux里tzselect命令是干什么的？

  tzselect号令用于选择时区。要留意的是tzselect只是帮我们把选择的时区显示出来，其实不会现实生效，也就是说它仅仅告诉我们怎么样去设置情况变量TZ。（TZ = Time Zone）（The

tzselect

program asks the user for information about the current location, and outputs the resulting time zone description to standard output。

The output is suitable as a value for the TZ environment variable。 All interaction with the user is done via standard input and standard error。

  ）若是你要永久更改时区，根据tzselect号令提醒的信息，在。profile或者/etc/profile中设置准确的TZ情况变量并导出。还有别的一种更改时区的办法就是间接更改系统设置装备摆设文件/etc/sysconfig/clock，然后修改符号链接/etc/locatime对应的文件，详见示例三。

#? 1

The following information has been given:

China

east China - Beijing, Guangdong, Shanghai, etc。

Therefore TZ='Asia/Shanghai' will be used。

Local time is now:

Mon Dec

6 09:40:35 CST 2010。

Universal Time is now:

Mon Dec

6 01:40:35 UTC 2010。

Is the above information OK?

1) Yes

2) No

#? 1

You can make this change permanent for yourself by appending the line

TZ='Asia/Shanghai'; export TZ

to the file '。

  profile' in your home directory; then log out and log in again。

Here is that TZ value again, this time on standard output so that you

can use the /usr/bin/tzselect command in shell scripts:

Asia/Shanghai

[root@new55 ~]#

如今要做的工作就是根据提醒，把

TZ='Asia/Shanghai'; export TZ

添加到。

  profile中（bash对应加到。bash_profile）。
