is it possible to use Delayed Extended in a command line?

[Hugo]

This works ok in a bat file:

Code: Select all

@echo off
setlocal enabledelayedexpansion
for %%i in (*.txt) do (set Name=%%~nxi&echo ren "%%i" "!Name:~0,5!-MyNewText-!Name:~5!")

(insert text in the middle of the file name)

But in a single command line:

Code: Select all

@echo off&setlocal enabledelayedexpansion&(for %i in (*.txt) do (set Name=%~nxi&echo ren "%i" "!Name:~0,5!-MyNewText-!Name:~5!"))&echo on

It does not work because of the variable Name

I wonder if there is any way to do this (just curious)

remove the extra ( and ) from your command, that could be the reason i'm not sure though

@echo off&setlocal enabledelayedexpansion&(for %i in (*.txt) do (set Name=%~nxi&echo ren "%i" "!Name:~0,5!-MyNewText-!Name:~5!"))&echo on

Hi abc0502

No, the result is the same.
The problem is with Delayed Extended applied to the variable "Name", !Name! does not work

There are a few commands that don't work in the command line, like CALL, GOTO and SETLOCAL. This way, it is not possible to Enable Delayed Expansion from the command line. However, if you start cmd.exe with Delayed Expansion enabled (with CMD /V:ON or via a registry value), then your command line should work.

Yes, this works:

Code: Select all

for %i in (*.txt) do @cmd /vo:n /c "set name=%~nxi&@echo ren "%i" "!Name:~0,5!-MyNewText-!Name:~5!""

It works!!!
Thanks Endoro!

It works, but for the records this is better:

Code: Select all

for %i in (*.txt) do @cmd /v:on /c "set "name=%~nxi"&@echo ren "%~i" "!Name:~0,5!-MyNewText-!Name:~5!""

Hi Endoro,
if I understand correctly, %~i is to remove the doble quotes inside %i. But I think that in

Code: Select all

for %i in (*.txt) ...

the var %i never has doble quotes. Am I wrong?

[Endoro]

No, you are completely right. I do this by custom

Thanks
