I am a mac user and I have maple installed on my computer. I can open maple like any other app. However I would like to work in terminal. I googled and
found that I can do that but I need to change some path. It was not well explained. I would really appreciate if someone can help me setting my path.
Thanks in advance.
You do not have to adjust the PATH environment variable. Doing so just makes calling the maple launch script for the Commandline Interface (aka CLI) a little easier.
Open a terminal window (xterm). Find the maple script of your Maple installation. Perhaps it will be located in some directory like /Library/Frameworks/Maple.framework/Versions/Current/bin/ say. You should be able to run that script in your terminal by running it using the full name, eg. /Library/Frameworks/Maple.framework/Versions/Current/bin/maple.
You could also alias the full name (explicit location) to some single short word.
That maple script sets everything it needs to run the Maple binaries, etc. You just have to run it (in a terminal).
Or you could make OSX launch a terminal window and call the maple script. Doesn't OSX have an automator for adding such things to the Dock? I forget the syntax but could it be something like,
open -a "/opt/X11/bin/xterm" --args "-e /Library/Frameworks/Maple.framework/Versions/Current/bin/maple"

I really like coding in bash, but there used to be many limitations of bash functionality in Windows. Though now there are many benefits to the bash windows users now rather than how it was pre windows 10. However, with all of the improvements, there is one thing that I feel leaves to be desired for me. The default behavior of the double-click of .sh files never really was able to do anything in windows, the .sh file extension isn't even available in the "choose default apps by file type" section of the settings. I had a desire to be able to change the default action for .sh files but neglected it and shook it off for a while, but this link finally gave me hope.
Before Ubuntu terminal and the addition of Windows subsystem for Linux, there was really no way to access bash terminal on Windows without a VM. Now with the addition of Windows Terminal which combines Microsoft Azure Terminal, Command Prompt, Powershell, and Ubuntu, it is really awesome for people like me, but despite the new awesome additions to windows allowing further integration of Linux terminal into Windows, even being able to edit the C: drive with Ubuntu.
I am sure there is a way to allow double-click of .sh files to open in windows terminal Ubuntu, but I don't know how. This question helped me on my journey to figure out how to do it and helped me make the default .bat file behavior change to Windows terminal, but I still have come to an enpass where I truly believe that it is not possible. So here is where I go when I have given up, the magical land of Stack Overflow :)
Attempts
So far I have looked into the "Choose default apps by file extension" section of settings and could not find .sh in there nor could I find it in any of the default apps sections of normal settings.
After I couldn't find anything about .sh in settings, I looked into the registry and looked for HKEY_CLASSES_ROOT and looked for sh or anything bash file related in HCR alone, HCR\*\shell, HCR\*\shellx, and HCR\*\Openwithlist and could not find anything.
I then tried to do ftype, but I could not find how to use ftype with .sh. I tried doing ftype .sh="C:\Users\asian\AppData\Local\Microsoft\WindowsApps\wt.exe" -p "Ubuntu" "%1" %* but i got the error "File type '.sh' not found or no open command associated with it."
I Also tried just clicking the .sh file so it brings up the "How do you want to open this file" menu and went to Windows Terminal but it opened the bash file in powershell with the error [error 0x800700c1 when launching `C:\Users\asian\Desktop\test.sh']
These where everything I could think of and none of it was working. Help and pointers are appreciated. Thank you!
I suggest you install the Git for Windows package, as it comes with a light-weight bash environment. This is likely to be able to be in the list of available apps when right-click -> Properties on a .sh or .bash file and say Open With and click the Change button next to Open With.
Other options are Cygwin or WSL for a 95% pure Linux environment on Windows.
So I am looking for a way to set Mac specific extended attributes (specifically kMDItemWhereFroms) for a file (Image File, Jpg) using AppleScript or AppleScript-Objc.
There is a command line tool that will do this xattr -w kMDItemWhereFroms . The problem is that on the several machines that I have access to (10.12, 10.13, and 10.14) when you run this command as a do shell script from within an AppleScript it does not work, the metadata is not added to the file. If I set Script Debugger to debug mode, and go through the script step by step it will actually set the metadata, but since that is not the way I am running the script, it is more of an interesting fluke than anything else. I have tried running the command with both "com.apple.metadata:" included and not included with the shell script and that makes no difference.
I have tried running my script through SD, Script Editor and osascript, and they all fail to update the metadata. So I am thinking that this tool might be broken when called from an AppleScript.
I found setxattr but that looks like it only applies to C.
So my questions are
1. Is there a way to set the extended attributes of a file on MacOS using Aobjc? if not then
2. Is there a way to get setxattr to work with either version of AppleScript? Probably not so
3. Any ideas how I might be able to get the command line tool xattr -w kMDItemWhereFroms to work when using scripting?
This is more of an annoyance for me, I am just being stubborn with wanting the source of the file to show up in the "Where From" data in the Get Info window from the Finder. I already am setting some metadata for the file using exiftool. So it is more of an interesting problem for me, than a critical problem that I must try and solve now. Thanks!
I have a bash file that does some file manipulation. I don't want to have to open the terminal every time I run it. Is there a way to make the program run when I double click it? (Like a windows .exe file)
Thanks
You can add a ".command" extension to the filename -- then double-clicking it will automatically open Terminal and run the script in a new window. Note: this assumes you still want to watch/interact with the script via a Terminal interface; if you want to avoid this as well, wrapping the script with Platypus, AppleScript, or Automator (as Zifei and Ned suggest) would be better options.
What you need is Platypus.
Platypus is a developer tool for the Mac OS X operating system. It can be used to create native, flawlessly integrated Mac OS X applications from interpreted scripts such as shell scripts or Perl and Python programs. This is done by wrapping the script in an application bundle directory structure along with an executable binary that runs the script.
The easiest thing to do is to type: sudo chmod 755 the_file_Name.This will allow you to double click on the file in the finder.
With OS X 10.5+, you can wrap the bash shell script in an AppleScript application using the AppleScript editor or an Automator application using Automator.app (see the Automator on-line help).
You could write (and there are apps out there that do this) an OS X app that accepts arbitrary .sh files and executes them. However, that's generally a bad idea as it could open you up to attacks if you inadvertently download a malicious shell script file that is automatically opened by your web browser. Better to be explicit.
I want to launch an app on OSX from a script. I need to pass some command line arguments. Unfortunately, open doesn't accept command line args.
The only option I can think of is to use nohup myApp > /dev/null & to launch my app so it can exist independently of the script that launches it.
Any better suggestions?
As was mentioned in the question here, the open command in 10.6 now has an args flag, so you can call:
open -n ./AppName.app --args -AppCommandLineArg
In OS X 10.6, the open command was enhanced to allow passing of arguments to the application:
open ./AppName.app --args -AppCommandLineArg
But for older versions of Mac OS X, and because app bundles aren't designed to be passed command line arguments, the conventional mechanism is to use Apple Events for files like here for Cocoa apps or here for Carbon apps. You could also probably do something kludgey by passing parameters in using environment variables.
An application bundle (.app file) is actually a directory. Instead of using open and the .app filename, you can move into the app's directory and start the actual machine code program located inside. For instance:
$ cd /Applications/LittleSnapper.app/
$ ls
Contents
$ cd Contents/MacOS/
$ ./LittleSnapper
That is the actual binary executable that might accept arguments (or not, in LittleSnapper's case).
In case your app needs to work on files (what you would normally expect to pass as: ./myApp *.jpg), you would do it like this:
open *.jpg -a myApp
You can launch apps using open:
open -a APP_YOU_WANT
This should open the application that you want.
open also has an -a flag, that you can use to open up an app from within the Applications folder by it's name (or by bundle identifier with -b flag). You can combine this with the --args option to achieve the result you want:
open -a APP_NAME --args ARGS
To open up a video in VLC player that should scale with a factor 2x and loop you would for example exectute:
open -a VLC --args -L --fullscreen
Note that I could not get the output of the commands to the terminal. (although I didn't try anything to resolve that)
I would recommend the technique that MathieuK offers. In my case, I needed to try it with Chromium:
> Chromium.app/Contents/MacOS/Chromium --enable-remote-fonts
I realize this doesn't solve the OP's problem, but hopefully it saves someone else's time. :)
Lots of complex answers when you can simply access Applications folder and type:
open -a [APP NAME]
This is it!
I wanted to have two separate instances of Chrome running, each using its own profile. I wanted to be able to start them from Spotlight, as is my habit for starting Mac apps. In other words, I needed two regular Mac applications, regChrome for normal browsing and altChrome to use the special profile, to be easily started by keying ⌘-space to bring up Spotlight, then 'reg' or 'alt', then Enter.
I suppose the brute-force way to accomplish the above goal would be to make two copies of the Google Chrome application bundle under the respective names. But that's ugly and complicates updating.
What I ended up with was two AppleScript applications containing two commands each. Here is the one for altChrome:
do shell script "cd /Applications/Google\\ Chrome.app/Contents/Resources/; rm app.icns; ln /Users/garbuck/local/chromeLaunchers/Chrome-swirl.icns app.icns"
do shell script "/Applications/Google\\ Chrome.app/Contents/MacOS/Google\\ Chrome --user-data-dir=/Users/garbuck/altChrome >/dev/null 2>&1 &"
The second line starts Chrome with the alternate profile (the --user-data-dir parameter).
The first line is an unsuccessful attempt to give the two applications distinct icons. Initially, it appears to work fine. However, sooner or later, Chrome rereads its icon file and gets the one corresponding to whichever of the two apps was started last, resulting in two running applications with the same icon. But I haven't bothered to try to fix it — I keep the two browsers on separate desktops, and navigating between them hasn't been a problem.
Beginning with OS X Yosemite, we can now use AppleScript and Automator to automate complex tasks. JavaScript for automation can now be used as the scripting language.
This page gives a good example example script that can be written at the command line using bash and osascript interactive mode. It opens a Safari tab and navigates to example.com.
http://developer.telerik.com/featured/javascript-os-x-automation-example/
osascript -l JavaScript -i
Safari = Application("Safari");
window = Safari.windows[0];
window.name();
tab = Safari.Tab({url:"http://www.example.com"});
window.tabs.push(tab);
window.currentTab = tab;
Simple, here replace the "APP" by name of the app you want to launch.
export APP_HOME=/Applications/APP.app/Contents/MacOS
export PATH=$PATH:$APP_HOME
Thanks me later.
With applescript:
tell application "Firefox" to activate
Why not just set add path to to the bin of the app. For MacVim, I did the following.
export PATH=/Applications/MacVim.app/Contents/bin:$PATH
An alias, is another option I tried.
alias mvim='/Applications/MacVim.app/Contents/bin/mvim'
alias gvim=mvim
With the export PATH I can call all of the commands in the app. Arguments passed well for my test with MacVim. Whereas the alias, I had to alias each command in the bin.
mvim README.txt
gvim Anotherfile.txt
Enjoy the power of alias and PATH. However, you do need to monitor changes when the OS is upgraded.
To Create a New Text File OR open an existing one, in any folder, using a Text/Code Editor like the Free TextMate app on MACOSX, use this command on Terminal:
open -n /Applications/TextMate.app --args "$PWD/some file.txt"
Instead of a Text File, you can use any file type, based on your app's requirements and its support for this syntax.
This command also simulates the New Text Document Here Command on Windows and has been tested on MacBook Pro 2021 and Monterey 12.2.1 successfully.
the background is a shell script to open the .m3u file of a web radio station. Therefore I want to know inside the script, what's the user's program to open such files. At the moment, he has to set the environment variable $PLAYER, but obviously that is not a good way to go.
Alternative: Is there a command that takes a filename and searches itself for an appropriate program to handle that file? Like file, e.g.,
open-file my_playlist.m3u
The script should be portable, it will run at least on Ubuntu, Debian and Windows/Cygwin machines.
Cheers,
This will have to be done differently on each platform. On Mac OS X the "open" command will do what you want.
In Linux it gets murky, since the desktop environment (GNOME or KDE) keeps its own list of applications to run for each file type.
There are two files you can look for in Ubuntu / GNOME that hold this info:
~/.local/share/applications/defaults.list and
~/.local/share/applications/mimeinfo.cache
Someone else hopefully knows how to do this in Windows and can chime in.
Edit: Stealing from the other answers:
Linux:
xdg-open [filename]
Cygwin:
cygstart [filename]
And for completeness, here's a link to a previous question about how to detect which operating system you are running on: Detect OS from bash Script
I'd like if there were a different answer to this but I think you'll have to check the file association configs for every desktop environment and file manager out there (so, nautilus, konqueror, thunar, mc... all in different places and in different formats AFAIK), as well as ascertaining which one of these the user is actually using...
If someone has a different idea I'm keen to hear it.
