help! replace spaces in file name with underscore

[hugo929]

for example the file name: AMD 1820 7609 29000 30GC.jpg
may have at least one space in it.
how to write the script to replace the space in the file name with underscore ?
that is:
AMD 1820 7609 29000 30GC.jpg
--->
AMD_1820_7609_29000_30GC.jpg

attention: the space numbers may varies.

thanks for your help in advance.

There are lots of auto renaming file tools. I dont know what OS you are using, so use Google.

I use total commander and serach and replace function. Check if that works for you.

Lupas rename works pretty well for me. It has a GUI, is straightforward to use and has preview functions.

thanks for all your guy's kind help.

I finally succeeded to fix the problem by writing a small dos codelet

Here is it:


for /f "tokens=1,2,3,4,5,6,7 delims= " %%A in ('dir/b *.jpg') do (
IF "%%B"=="" (rem
)else IF "%%C"=="" (ren "%%A %%B" %%A_%%B
)else IF "%%D"=="" (ren "%%A %%B %%C" %%A_%%B_%%C
)else IF "%%E"=="" (ren "%%A %%B %%C %%D" %%A_%%B_%%C_%%D
)else IF "%%F"=="" (ren "%%A %%B %%C %%D %%E" %%A_%%B_%%C_%%D_%%E
)else IF "%%G"=="" (ren "%%A %%B %%C %%D %%E %%F" %%A_%%B_%%C_%%D_%%E_%%F
)
)
