I don't like Windows-style data output and using %date:~6,4%-%date:~3,2%-%date:~0,2% for backup, it gives YYYY-MM-DD format

I like the nested () after the do in the for loop. But seem to be having problems with nested for loops within it, as I want to take the first loop variable and add the second loop variable to it using the SET /A command...doesn't seem to work. would be a great way to increment or decrement a number for file manipulation....
any ideas?

The next code does the job. I know it does the job using a different approach, but I guess the end result is the same as you wanted it.
Hope it helps...
Note: Because of the line "set /a count=%count%+1" this script works well under cmd, but not under good old command.com.

SET count=0

:new_col
set /a count=%count%+1
if %count%==9 goto end
SET Colour=Colour%count%
goto get_col

:get_col
if "%Colour%"=="Colour1" set Colour=BLACK
if "%Colour%"=="Colour2" set Colour=BLUE
if "%Colour%"=="Colour3" set Colour=GREEN
if "%Colour%"=="Colour4" set Colour=CYAN
if "%Colour%"=="Colour5" set Colour=RED
if "%Colour%"=="Colour6" set Colour=PURPLE
if "%Colour%"=="Colour7" set Colour=ORANGE
if "%Colour%"=="Colour8" set Colour=GRAY
goto show_col

:show_col
ECHO Colour is %Colour%
goto new_col

:end

How about answering the question 'using variables in batch files' ...
printing the variables doesn't really amount to 'use'

When you've learned this it's easy to use it for backup purposes, like this one:

-----------------------------------------------------------------------------
md "C:\test\Backup %date%"
set bkpdir="C:\test\Backup %date%"

xcopy C:\temp %bkpdir% /E /C /Q /H /Y
-----------------------------------------------------------------------------

All you have to do is schedule this script to run each night or whenever you like, using windows scheduler. Works like a charm :)

ahh! you can do this via a variable in the batch file. you'd need to files or use functions to do this.

so we have two files; input.bat and variable.bat

we will have a command in input.bat that creates a basic directory listing of a folder and then can pass the variable onto the variable.bat which will then echo the results to a log.txt file.

variable.bat:
echo %1 >> log.txt

input.bat
for /f "tokens=1 delims=\" %%a in ('dir /b "C:\"') do (variable.bat %%a)

it should do a dir with bare flag, C:\ and then send just the folder names to the variable.bat. the %1 is the variable thats read from the input.bat. you can use %1 %2 %3 and have 3 variables passed :)

hope that helps!

Hey,

i was wondering a long time ago if it was possible to use the value of one variable, in order to define another.

example:

set /p var1=Please enter a number:
set /a value=string%var1%
echo %value%

any help would be greatly appreciated

Re: Using variables in Windows batch files

Rich — Tue, 23 Feb 2010 12:39:53 -0000

I want to create a batch file that looks at a list of files, and zips like files together, then deletes the files that were zipped.

Example: a folder contains:

file1.xyz
file1_6.abc
file2_1.abc
file3.xyz
file3_0.abc

The batch file should:
1) combine file1.xyz and file1_6.abc into a file called file1_6.zip
2) skip file2_1.abc (since it has no other file "like" it)
3) combine file3.xyz and file3_0.abc into a file called file3_0.zip
4) delete file1.xyz, file1_6.abc, file3.xyz, file3_0.abc (since they are now in a new zip file)

This is just a simple example - the actual file list may consist of 100's of files...

Right now I create a list of the files with the dir command, import into excel, go through a whole lot of mmanipulation to create a batch file that contains a line of code for every specific file combination. I'd like to use variables and looping? to recurse the directory to perform the needed actions.

HELP!
