Using For Loop to Rename All Files in a Folder<\/span><\/div>\n

<\/div>\n
This is the batch script for windows to rename\u00c2\u00a0all files in a folder on windows. This works well perfectly. This was useful for me. It may help others to do the same. I was worried to change the files name and folder using script, atlast i find my script to fix the issue.<\/div>\n

<\/div>\n
<\/div>\n
rem: Some testing batch command in Windows XP<\/div>\n
<\/div>\n
setlocal ENABLEDELAYEDEXPANSION<\/div>\n

<\/div>\n
rem ***************** Test 1 **********************<\/div>\n
rem about variables<\/div>\n
<\/div>\n
set var1= This is a variable VAR1<\/div>\n
set var2=\u00e2\u20ac\u2122This is a variable VAR2\u00e2\u20ac\u00b2<\/div>\n
set var3=\u00e2\u20ac\u009dThis is a variable VAR3\u00e2\u20ac\u00b3<\/div>\n
echo %var1%<\/div>\n
echo \u00e2\u20ac\u02dc%var2%\u00e2\u20ac\u2122<\/div>\n
echo \u00e2\u20ac\u0153%var3%\u00e2\u20ac\u009d<\/div>\n
<\/div>\n
rem ***********************************************<\/div>\n
rem Conclusion from test 1 is that assigning text<\/div>\n
rem value to variable doesn\u00e2\u20ac\u2122t need to be quoted<\/div>\n
rem ***********************************************<\/div>\n
<\/div>\n
rem **************** Test 2 **********************<\/div>\n
rem about for loop<\/div>\n
<\/div>\n
set count=0<\/div>\n
for %%a in (1 2 3) do (<\/div>\n
echo !count!<\/div>\n
set \/A count=!count!+1<\/div>\n
echo %%a<\/div>\n
)<\/div>\n
<\/div>\n
for %%A in (1 2) do for %%B in (A B) DO ECHO %%A%%B<\/div>\n
<\/div>\n
rem **********************************************<\/div>\n
rem Conclusion from test 2 is that variable in<\/div>\n
rem the for loop has to be single character like<\/div>\n
rem %%a. %%var will not work<\/div>\n
rem you don\u00e2\u20ac\u2122t have to have<\/div>\n
rem setlocal ENABLEDELAYEDEXPANSION for the count<\/div>\n
rem to work but you do have to use !count! instead<\/div>\n
rem of %count%<\/div>\n
rem **********************************************<\/div>\n
<\/div>\n
rem **************** Test 3 **********************<\/div>\n
rem use for loop to list all .txt file names<\/div>\n
<\/div>\n
for \/f %%a in (\u00e2\u20ac\u2122dir \/b transaction*.txt\u00e2\u20ac\u2122) do (<\/div>\n
echo %%a<\/div>\n
)<\/div>\n
<\/div>\n
rem **********************************************<\/div>\n
rem I don\u00e2\u20ac\u2122t know what the switch \/f in the for<\/div>\n
rem statement and the \/A switch in the set<\/div>\n
rem statement mean but it works.<\/div>\n
rem Can someone explain the switch? =)<\/div>\n
rem **********************************************<\/div>\n
<\/div>\n
rem **************** Test 4 **********************<\/div>\n
rem rename all .txt file so that all of them<\/div>\n
rem starts with \u00e2\u20ac\u0153trans\u00e2\u20ac\u009d instead of \u00e2\u20ac\u0153transaction\u00e2\u20ac\u009d<\/div>\n
<\/div>\n
for \/f \u00e2\u20ac\u0153tokens=1,2 delims=_\u00e2\u20ac\u009d %%a in (\u00e2\u20ac\u2122dir \/b transaction*.txt\u00e2\u20ac\u2122) do (<\/div>\n
if \u00e2\u20ac\u0153%%a\u00e2\u20ac\u009d==\u00e2\u20ac\u009dtransaction\u00e2\u20ac\u009d echo yes<\/div>\n
echo %%a<\/div>\n
echo %%b<\/div>\n
ren %%a_%%b tran_%%b<\/div>\n
)<\/div>\n
<\/div>\n
rem **********************************************<\/div>\n
rem The above script works fine. It renames all<\/div>\n
rem files named in partern transaction_XXXX.txt<\/div>\n
rem to trans_XXXXX.txt<\/div>\n
rem \u00e2\u20ac\u0153tokens=1,2 delims=_\u00e2\u20ac\u009d tells it to separate<\/div>\n
rem whatever returned in dir command in two parts<\/div>\n
rem using the first \u00e2\u20ac\u0153_\u00e2\u20ac\u009d found and put the first<\/div>\n
rem token in %%a, the second in %%b.<\/div>\n
rem It is very powerful and interesting!<\/div>\n
rem **********************************************<\/div>\n
<\/div>\n
goto :eof<\/div>\n
<\/div>\n
<\/div>\n
<\/div>\n
<\/div>\n
One additional remark: if you decide NOT to set ENABLEDELAYEDEXPANSION, then the !variable! syntax fails. Not sure if that means that %variable% would work in that situation instead, but just thought I\u00e2\u20ac\u2122d be explicit about where ENABLEDELAYEDEXPANSION had an effect (though obviously it\u00e2\u20ac\u2122s relevant in other parts too)<\/div>\n
