Wildcards in Strings

Hey guys,
I need to know if you can put wildcards in strings. For example, I want to make an error message appear if the command has the right prefix, but an invalid extension.
Here is where I want the wildcard to be inserted:
Code: Select all
set var1=iexplore
set var2=notepad
set var3=chrome
set /p command=^>
if /I "%command%"=="start %var1%" start %var1%
if /I "%command%"=="start %var2%" start %var2%
if /I "%command%"=="start %var3%" start %var3%
if /I "%command%"=="start [WILDCARD]" echo Unknown Application!

Solution to both threads you made:
Code: Select all
set exes=iexplore,notepad,chrome
set /p command=^>
if /I "%command:~,5%"=="start" (
for %%x in (%exes%) do (
if /I "%command:~6%"=="%%x" (
start %%x
set started=1
))
if defined started (set start=) else echo Unknown Application!
)

Great! It works just the way I want it to! Thanks!
Just one more thing. I want to change "start" to something else. I tried changing it and it didn't work. Is this because of the ":~,5" or is it something else?

Yes, that's character length. Say the command was echo, it should be ":~,4". That syntax means "from __ to 4" (__ defaults to 0, same as ":~0,4").
Negative values can be used to go from the end of the string too.
http://ss64.com/nt/syntax-substring.htmlThe solution could be made better though, so you don't need substrings.
Code: Select all
set exes=iexplore,notepad,chrome
set /p command=^>
for /f "tokens=1*" %%x in ("%command%") do (
if /I "%%x"=="start" (
for %%z in (%exes%) do (
if /I "%%y"=="%%z" (
start %%z
set started=1
))
if defined started (set start=) else echo Unknown Application!
))
is pretty much the most useful batch command. Essential to learn.
By the way, if you're just trying to change the command prompt character for the session... try
prompt /?.

Could you re-post the code that you posted last night? I accidentally overwrote the file with the code and I can't get this one to work like I want it to.

Uhm, which? Both codes are still in the thread here.

The one that I quoted. It didn't have the "for" command in it before.

Before I edited my first response, I think this is what I changed:
Code: Select all
set var1=iexplore
set var2=notepad
set var3=chrome
set /p command=^>
if /I "%command:~,5%"=="start" (
if /I "%command:~6%"=="%var1%" (start %var1%
) else if /I "%command:~6%"=="%var2%" (start %var2%
) else if /I "%command:~6%"=="%var3%" (start %var3%
) else echo Unknown Application!
)
Not a good solution though.
