windows - Why does %%I work in .cmd? -


i have found in multiple online forums , blogs .cmd files utilize %i (or %a, etc.) loops , batch files require 2 percent symbols (%%i). however, line of code has been working me in .cmd file:

for /l %%i in (%case%, 1, %endcase%) ( aws s3 cp s3://[url]/%user%/%%i "c:\users\[directories]\accuracy_testing\datax\%user%_%%i" --recursive )

in code, using command line interface aws download files associated multiple ids. case , endcase arguments parsed file.

why work, when .cmd files should using %i instead of %%i?

you're confusing .cmd files cmd prompt. .cmd files batch files (with few differences people won't notice), while cmd prompt command line itself.

scripts use %%i, command prompt uses %i.

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
