I have a program that generates bunch of files automatically. i don't have control on the base program. I need to be able to change the names of the files. Here is a sample.

tblEmployee.cs -> Employeedto.cs
tblDept.cs -> Deptdto.cs

I need to remove 'tbl' from the prefix and add 'dto' as the suffix before the file extension.

can someone please provide me the code for this renaming in MS DOC batch file?


Thanks a bunch,
Chandra

Give this a try.

@echo off
Set local enabledelayedexpansion
Pushd c:\yourdir
For %%A in (tbl*.cs) do (
  Set Name=%%~nA
  Ren "%%~A" "!Name:~3!dto.cs"
)
Popd

Open in new window

Script:
@echo off
Set local enabledelayedexpansion
Pushd c:\Users\Chandra\temp
  For %%A in (tbl*.cs) do (
  Set Name=%%~nA
  Ren "%%~A" "!Name:~3!dto.cs"
)
Popd


Result:
C:\Users\Chandra\temp>changename.bat
LOCALAPPDATA=C:\Users\Chandra\AppData\Local

Nothing ever in the clear!

This technical paper will help you implement VMware’s VM encryption as well as implement Veeam encryption which together will achieve the nothing ever in the clear goal. If a bad guy steals VMs, backups or traffic they get nothing.

The script would work as is IMO except there is a spurious space on the set local line.  Changed to just setlocal it should be fine.

Sorry for the extra space in setlocal, worked this question on a mobile device and it was nice enough to put in that space on its own, argh.

Given the posters final comment, shouldn't http:#a38716455 be accepted as the solution or at least a points scoring assist, in which case the poster should post their modified working version.

Agreed give Bill the points, was only a space added!

My mobile seems to auto-complete words really annoyingly and doesn't seem to allow turning it off in a browser text box, you hit a space after a word in a piece of code and it helpfully adds the last bit of text you had after that combination etc.  Must delve a bit for the "off" button on that I suppose!
