Theme changer

I got two css style sheets, one is green the other one dark-purple.

Now i was thinking that every 12 hours, themes would switch from green (7 am) to purple at 7pm.
Could this be done with cronjobs, how?
If so with php maybe
if
else
but i think that'd be a little too complex no?

with cronjob you could change the filename,
e.g. you have style1.css and style2.css. At 7 am style1.css would then be renamed to style2.css and style2.css would become style1.css.
your code should then only refer to style1.css

but i would do it in php, less complicated and is easier to see what is happening.
some seudo code could be


try take a look at the time function.

I know that but now i realise i want to use crontabs just to get to know it i used it to run scripts but not to rename a filename. How?
I could execute a php file that changes the name of 2 files, but that wouldn't be the same

Just write two shell scripts; one that links stylesheet.cs and purple.cs at 7pm, and another that links stylesheet.cs and green.cs at 7am. Both of these scripts should be one liners, and you already know how to run a script from cron .

Note: you don't have to use links, you can just copy the appropaite file to the stylesheet.cs if you wish.

Take care,

What command can i use to just rename a directory? In crontab? Thank you.

I'd go for:

Thank you very much
mv style1.css style3.css
then
mv style2.css style1.css
?

It takes 3 steps to swap two files in place. This can be written inline like so.
