Hi All,

The following rename command works from the DOSBox 0.74 command prompt, but it does not appear to work from inside a batch file running on DOSBox 0.74 :-

ren FILEBR~2.JAR TEMP.JAR

Please can you advise if there is a way to get this working (other than to copy and then del source) ?

Thank you for your time,
Best regards,
James

Are you sure the line is being executed ?

(as lately I got an email asking why

hello.bat
echo "hi"

(didn't work, it should be call hello.bat inside the bat file)

Hi Qbix,

Yes it's being executed. I've tested it in a one-line batch file. But it's actually no problem for me to "copy FILEBR~2.JAR TEMP.JAR" and then "if exist TEMP.JAR del FILEBR~2.JAR". So I can just do that. 😀

For your information, I'm running DOSBox 0.74 on Windows 7 Professional (64 bit / version 6.1.7601) and FILEBR~2.JAR full name under Windows is "FileBrowser1.jar".

Cheers,
James

The ~2 part indicates it's the second occurrence of that shortened file name. Have you tried it it with ~1?

Hi SKARDAVNELNATE,

The rename doesn't work with ~1 either. But it is easy to workround using copy and delete. See example batch file ("TEST.BAT") and output produced.

Cheers,
James

@echo off
echo ----All files before rename---->TEST.OUT
dir /b>>TEST.OUT
echo ----ABC files before rename---->>TEST.OUT
dir /b *.ABC>>TEST.OUT

REM Rename fails silently
ren LONGFI~1.ABC  XXXXXX.ABC >>TEST.OUT

echo ----All files after rename---->>TEST.OUT
dir /b>>TEST.OUT
echo ----ABC files after rename---->>TEST.OUT
dir /b *.ABC>>TEST.OUT

REM Copy and delete both succeed
copy LONGFI~1.ABC  YYYYYY.ABC >>TEST.OUT
del LONGFI~1.ABC >>TEST.OUT

echo ----All files after copy and delete---->>TEST.OUT
dir /b>>TEST.OUT
echo ----ABC files after copy and delete---->>TEST.OUT
dir /b *.ABC>>TEST.OUT
----All files before rename----
LONGFI~1.ABC
TEST.BAT
TEST.OUT
----ABC files before rename----
LONGFI~1.ABC
----All files after rename----
LONGFI~1.ABC
TEST.BAT
TEST.OUT
----ABC files after rename----
LONGFI~1.ABC
 LONGFI~1.ABC
   1 File(s) copied.
----All files after copy and delete----
