Best regards
Tanjm

[Laurent Menase]

in what occasion?
on which output?

[Laurent Menase]

do you just mean
date +%y%m%d

[Tan jianmin]

Dear Laurent Menase:
Thanks a lot for your quickly reply.
Use date +%y%m%d command just change the output once.I want to make it effective permanently.

[Laurent Menase]

but for what command output?
only date?
ls?

[Tan jianmin]

The output of date %y%m%d command is below.
# date +%y%m%d
090914

When I use date command again,the output is below.
# date
Mon Sep 14 16:55:36 EAT 2009

I want to use date command to get the output just like date +%y%m%d command.How do I change the format of the date.

[Laurent Menase]

you must use localdef to change the LC_TIME table definition

[Tan jianmin]

Thanks,I'll try it.

[Laurent Menase]

to display the current one use
locale -k LC_TIME

Hi

Another option, create an alias in your user profile. Add this line :

alias date='date +%y%m%d'

You can try it online.

If you want to get back the original output (without unalias it) type de command date between quotes.

'date'

Regards,
Roland

>Roland: If you want to get back the original output type the command date between quotes.

You can also quote first char: \date

Thanks Dennis for this variant.
