How would I go about opening a .bat file meant for a Windows computer on a Mac? I know I would have to edit it/rewrite some of it, but what exactly do I edit?

Without knowing what the .BAT file actually contains, it's hard for us to know what you have to change..

You're going to have to change 99% of it, if not everything. OS X and Windows use two very different approaches to CLI scripting. If you post what you have, perhaps I (we) can help you rewrite it.

My father has helped with .bat files before, and I don't think he changed all that much of them. Anyway, this is the text in it.


@echo off
COLOR 09
title SilabGarza Client v3.6
cd .\FILES\
java -Xmx1000m -cp .;Theme.jar Bot 0 0 lowmem members 32
pause

For the future, it would also be helpful to know how to rewrite them myself, without having to resort to posting on the forum

P.S. When my father helped rewrite them, I am 99% sure he used Terminal. I'm not sure how he did that though, so any help would be appreciated

Still need help

BAT files are just text files. They contain script commands that Windows can interpret.

They can be edited on most platforms in any plain text editor (on OSX try TextEdit or Text Wrangler).

As to your question what to change . . . that's near impossible to answer. The file you've posted above appears to invoke a precompiled java app using a set of parameters.

I'd hazard a guess that it's a bespoke app of some kind.

You can change the commands by just typing/overtyping. But asking what to change is a nearly impossible question to answer from the info you've supplied I'm afraid.

You'd need to state what you are trying to do, what it does now and what it needs to do, but even then what you're asking is somewhat 'tricky'.

What's the end result you want to achieve? Are you trying to run this java app on Mac?

Yes, I'm trying to run the Java file on my Mac. If you need any other information, I'm afraid I don't know enough about this to help. All I know is that I have to rewrite it to make it run

Try the following:

#!/bin/sh
cd <location> (replace with the location of the jar)
java -Xmx1000m -cp .;Theme.jar Bot 0 0 lowmem members 32

If you still need the pause at the end, take a look at this.

By the "location of the jar" do you mean something like /Users/Name/Desktop/SilGar\ v3.6/FILES? I tried doing that, then I opened the BAT file in Terminal, and then it said:

/Users/danny/Desktop/SilGar v3.6/Run.bat: line 3: Theme.jar: command not found

And then below that, it says what I told the pause prompt to say.

Perhaps simply using the Jar Launcher app in OS X will suffice, and bypass the need for command line scripting.

Hold on, we're going to start over. First off, if Jar Launcher works for you, go with it. It may not work because it looks as if you're passing parameters to the jar file. Otherwise, let's start again.

First, open up an editor and paste in the following:

#!/bin/sh
java -Xmx1000m -cp .;<location>/Theme.jar Bot 0 0 lowmem members 32

Replace <location> with the location of the jar. So, using your example, if the jar file was in /Users/Name/Desktop/SilGar\ v3.6/FILES, make sure the contents of this file read as such:

#!/bin/sh
java -Xmx1000m -cp .;/Users/Name/Desktop/SilGar\ v3.6/FILES/Theme.jar Bot 0 0 lowmem members 32

Save that with the extension .sh. Make sure to save it as plain text (if you're using TextEdit, go to Format > Make Plain Text before saving). Now, open up a Terminal and type the following:

chmod +x <location of sh file>/<sh file>

For example:

chmod +x /Users/Name/jar_launcher.sh

Once that is done, your script is ready to execute. If you want to execute it, simply type the directory and name of the script at the Terminal prompt. For example:

/Users/Name/jar_launcher.sh

/Users/Name/jar_launcher.sh

What I tried did not work, so just to recap:

1. Edit the run.bat file to #!/bin/sh
java -Xmx1000m -cp .;<location> Bot 0 0 lowmem members 32, and save it with the extension .sh
2. Open terminal and enter chmod +x /Users/danny/Desktop/SilGar\ v3.6/Run.sh
3. Hit enter

Nice post lol

it's two commands:
1. "java -Xmx1000m -cp ."
-cp that will do a search for a class in the current dir, but why not just pass in the single class?
-Xmx100M is a setting for the heap size, what exactly are you trying to run lol?

2. "Theme.jar Bot 0 0 lowmem members 32"
you can retype this as:
java -jar Theme.jar Bot 0 0 lowmem members 32

I would edit the file in the following way:
java -Xmx1000m -cp .
java -jar Theme.jar Bot 0 0 lowmem members 32

save it in the same location as the original .bat, add execute permissions as described above

and dude, when some1 used <> it meant you needed to substitute that for the correct path, not write <location> in your script

Reading this might be useful. As it notes, if you put a semi-colon between two commands, it will execute the second regardless of whether there was an error with the first. If you put two ampersands between the commands, it will execute the second only if the first was successful.

So, you could put those two java commands on one line if you wanted:

java -Xmx1000m -cp . ; java -jar Theme.jar Bot 0 0 lowmem members 32

or

java -Xmx1000m -cp . && java -jar Theme.jar Bot 0 0 lowmem members 32
