[solved] Rename list of files

[didley]

Hi,

I'm looking for a solution for the problem how can I rename a list of files?
For example: ren Table_23454423.txt 2345423.txt. This works for one file. But I have a list of files like Table_XXXXX.txt and all should be renamed in XXXXX.txt.
I assume I need the command 'For' for it. But I don't know how I can use it. Is anybody there which can solve this problem?

didley,

Try this:
Create a batch file, i.e. myrename.bat
put the following code in it:

Code: Select all

@ECHO OFF
for %%a in (*.txt) do @set f=%%a&call ren "%%a" "%%f:~6%%"

The %%f:~6%% will cut off the first 6 characters.
For testing you can temporary replace the the 'ren' command with 'echo'.


Or from a command line run this:

Code: Select all

cmd /v:on /c "for %a in (*.txt) do @set f=%a&ren %a !f:~6!"

Now !f:~6! will cut off the first 6 characters.
Again for testing you can temporary replace the the 'ren' command with 'echo'.

kaputko,

Sure, here is one way this can be done:

Code: Select all

@ECHO OFF
SETLOCAL ENABLEDELAYEDEXPANSION
for %%a in (*.txt) do (
    set "f=%%a"
    set "f=!f:random numbers_=!"&REM REMOVES "random numbers_"
    set "f=!f:_-_= !"&REM REPLACES "_-_" WITH A SINGLE SPACE
    ren "%%a" "!f!"
)

Here another one:

Code: Select all

@ECHO OFF
SETLOCAL ENABLEDELAYEDEXPANSION
for %%a in (*.txt) do (
    set "f=%%a"
    ren "%%a" "!f:~15,3! !f:~21!"
)

works too because:
"!f:~15,3!" - extracts 3 characters beginning at position 15 (start couting at 0)
"!f:~21!" - extracts all characters after position 21 (start counting at 0)
