CD command

he can use that to cd to his previous location.

echo.      prints a blank line to the screen.

Yes I did know that. 

and yet you asked anyway?        .... odd.

Maybe English is not your first language? I meant, "What is the reason why you have put a period after the echo command?", not "What does a period do after an echo command?"

[Carbon Dudeoxide]

Lol, what does it matter.
I find it easier for me to use 'echo. text' than 'echo  text'
You dont have to use the period for %cd:~20,0% but i did coz i could......

he can use that to cd to his previous location.

Oh right. So I'm in D:\My Folders\*censored*\Mom don't look in here\Babes\Redheads and I

type CD d:\

So now I'm in d:\

I type your command and it cuts the last 20 characters off the directory name, which is actually 3 characters long, so I end up with an empty string, which ECHO interprets as a request to show ECHO status, so it says "ECHO is on", and that gets me back to my previous folder? Is that how it works?

That's a real clever DOS tip, dudeoxide! i would nevah have thunk of that all on my lonesome!

[Carbon Dudeoxide]

well then you change 20 to a number that suits you.

It's only useful if "where you were before" is  a parent folder of where you are now. typing cd.. (enter) and then repeatedly recalling it with the up arrow would do the same thing.

Reinaker: You can use PUSHD and POPD.

For example, if you start off in
Contrex's directory of
D:\My Folders\*censored*\Mom
And you want to go to the directory D:\Foo, you could use the command

Code: [Select]

pushd \FooThen to get back to the previous directory do

Code: [Select]

popdOr if you wanted to go to C:\Documents and Settings you could use the command

Code: [Select]

pushd "C:\Documents and Settings"Then to get back to the previous directory do

Code: [Select]

popd
Another tip ... if you are writing a batch file that changes directories and it ends up leaving you in a directory used by the batch file instead of the original, you can use the SETLOCAL command.  Example:

Code: [Select]

@echo off
setlocal
cd \Temp
ren *.new *.oldIn this example the batch file would leave you in whatever directory you started in.  Without the SETLOCAL command, the batch file would leave you in \Temp.
