bash - Which shebang line should I use? -


there scripts in project run fine without first line (like #!/bin/) – without interpreter path.

so these scripts running fine, in cases fail, when run – execute fine.

i need modify , put shell interpreter first line.

the problem here scripts fail when use #!/bin/ksh while others fail when use #!/bin/bash.

can tell me when use option?

how can make sure work fine, other way generalize , make interpreter common scripts?

each script written in programming language - bash, ksh, zsh, python, perl .... can't instance write python program , hope perl can run it. similarily, ksh program needs executed ksh, bash program bash.

now, since bash, ksh, zsh , posix shell do have common subset, possible execute of these command processors. if - , if! - sure applies these scripts, propose use posix shell, because restrictive one.

but if people designate script bash, or ksh, or else, maintainer of script might sooner or later use features particular 1 of shell languages. of course require programming in, say, ksh, political question, not technical one.

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

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
