Can i make a shell script executable in Mac without chmod stuff? - shell

I have seen that i can use chmod +x command in Mac to make a shell script executable. This works fine, but i have noticed that i have to do the same thing every time this shell script file is copied to another Mac computer.
Is there a way to make the shell script executable by default when double clicked, without such command ... As the shell script file will be given to many users, and doing this will be hard for some of them ?
Best regards.

If you pack your whole program in a .tar file (or in a .tar.gz-file, which is the same, but compressed), the executable-"permission" will be preserved.

Give it the '.command' extension and it can be executed from the Finder.

Creating a mac app which calls a shell script, but developing in ubuntu

I have a shell script, and a tarball. The shell script unpacks the tarball, and makes use of the files inside of for performing a task. I need to make this accessible on mac laptops, but in such a way that there is either a .app or .dmg file that when clicked, ultimately calls that shell script. I found several utilities, that can do this (create such an .app file), such as Platypus, or Appify. However, these require Mac to build the file. The thing is, I must package the .app/.dmg file, in an Ubuntu environment.
Is there any good software for creating a dmg or app file which call a shell script when clicked, but such that the software which can be run in Ubuntu (just for the purpose of creating the file)?
This is not an exact answer to your question but an workaround that might be acceptable if you can't find a better solution.
First, a zip file will automatically extract its content if you double click it in OS X so
tar -cvzf your_filename.zip ...
would create a file that can be easily extracted.
Secondly, if you create a shell script that has the extension .command, but otherwise is like any shell script, it can be run from OS X by double clicking on it (by opening a terminal and executing it there), it would mean an extra manual step for the user but like I said, this is a workaround :)
If you create a .command file, remember to make it executable.

Execute shell script when the file is opened

I want to make a shell script, which is executed when it is clicked on. I know you can do this with the Terminal command chmod u+x (filename) but I want to be able to send the file let's say by email or scp, and it should still be executed when clicked on by the new user.
I don't really think that is possible. The executability of the file is not an attribute within the file which tells the system to execute it. Its something you tell the system to do. I guess it is a security measure, regarding running maybe a risky command, lets say, rm -rf an important system folder.

Running an executable by calling it in a .sh file

I am very new to bash and using .sh files. I am trying to run the program aescrypt by calling it in a .sh file as follows (aescrypt is in the same directory as the .sh file) :
./aescrypt -e -p password file.txt
It throws the following error:
./aescrypt no such file or directory
Am I doing it wrong?
ps- I realy don't want to add it to the PATH variable as I will be using this on more than one computer that resets every day.
The location of the script is irrelevant. The thing that matters is the working directory of the process executing the script. The simplest solution really is to add aescrypt to a standard location like /bin or /usr/bin. If neither of those is acceptable, perhaps /usr/local/bin is an option. Otherwise, just use the full path of aescrypt in your script. Either hard code it, or if it is in the same directory as the script, try:
$(dirname $0)/aescrypt ...
(Note that hardcoding is more reliable, but less flexible. If you move the executable, the script will break. But using dirname will break if the script changes directory during execution.)
how about if you call the program like ./aescrypt.sh, thats the way to call an .sh programm througt the terminal
First off all, you have also to change the permissions of the file to make it executable, the way to make that is to write in the terminal, the command:
sudo chmod 765 aescrypt.sh
For that you have to be located where the file is

How do I run .sh or .bat files from Terminal?

I have a pretty basic problem here, that has happened so haphazardly to me that up until now, I've just ignored it. I downloaded tomcat web server and "Murach's Java Servlets and JSP" book is telling me to navigate to the tomcat/bin directory and start the server my typing in Terminal
$ startup
However, I get the error
-bash: startup: command not found
The relevant files in this directory are startup.sh and startup.bat. Typing both of these returns the same error message
So my questions are, what are .bat and sh files, and how do I run these files? I've read several tutorials for different languages and software programs, and some times when the tutorial says execute a bunch of files in the command line, I get a "command not found" error. Sometimes it works, sometimes it doesn't. This is perplexing to me, so what are some common solutions to solving these sort of "command not found" Terminal problems?
The .sh is for *nix systems and .bat should be for Windows. Since your example shows a bash error and you mention Terminal, I'm assuming it's OS X you're using.
In this case you should go to the folder and type:
./startup.sh
./ just means that you should call the script located in the current directory. (Alternatively, just type the full path of the startup.sh). If it doesn't work then, check if startup.sh has execute permissions.
This is because the script is not in your $PATH. Use
./scriptname
You can also copy this to one of the folders in your $PATH or alter the $PATH variable so you can always use just the script name. Take care, however, there is a reason why your current folder is not in $PATH. It might be a security risk.
If you still have problems executing the script, you might want to check its permissions - you must have execute permissions to execute it, obviously. Use
chmod u+x scriptname
A .sh file is a Unix shell script. A .bat file is a Windows batch file.
Type bash script_name.sh or ./script_name in linux terminal. Before using ./script_name make you script executeable by sudo chmod 700 script_name and type script_name.bat in windows.
Drag-And-Drop
Easiest way for a lazy Mac user like me: Drag-and-drop the startup.sh file from the Finder to the Terminal window and press Return.
To shutdown Tomcat, do the same with shutdown.sh.
You can delete all the .bat files as they are only for a Windows PC, of no use on a Mac to other Unix computer. I delete them as it makes it easier to read that folder's listing.
File Permissions
I find that a fresh Tomcat download will not run on my Mac because of file permission restrictions throwing errors during startup. I use the BatChmod app which wraps a GUI around the equivelant Unix commands to reset file permissions.
Port-Forwarding
Unix systems protect access to ports numbered under 1024. So if you want to use port 80 with Tomcat you will need to learn how to do "port-forwarding" to forward incoming requests to port 8080 where Tomcat listens by default. To do port-forwarding, you issue commands to the packet-filtering (firewall) app built into Mac OS X (and BSD). In the old days we used ipfw. In Mac OS X 10.7 (Lion) and later Apple is moving to a newer tool, pf.
Based on IsmailS' comment the command which worked for me on OSX was:
sudo sh ./startup.sh
On windows type either startup or startup.bat
On unix type ./startup.sh
(assuming you are located in tomcat/bin directory)
Batch files can be run on Linux. This article explains how (http://www.linux.org/threads/running-windows-batch-files-on-linux.7610/).
Type in
chmod 755 scriptname.sh
In other words, give yourself permission to run the file. I'm guessing you only have r/w permission on it.
add #!bin/bash on top of the your .sh file
sudo chmod +x your .sh file
./your.sh file
these steps work~
My suggestion does not come from Terminal; however, this is a much easier way.
For .bat files, you can run them through Wine. Use this video to help you install it: https://www.youtube.com/watch?v=DkS8i_blVCA. This video will explain how to install, setup and use Wine. It is as simple as opening the .bat file in Wine itself, and it will run just as it would on Windows.
Through this, you can also run .exe files, as well .sh files.
This is much simpler than trying to work out all kinds of terminal code.
I had this problem for *.sh files in Yosemite and couldn't figure out what the correct path is for a folder on my Desktop...after some gnashing of teeth, dragged the file itself into the Terminal window; hey presto!!

Locking the contents of shell file

I have scripted a program in shell and the file is executable. Now I want to put this file on a server so that all my friends can use it but at the same time I want to make it sure that they are not allowed to fiddle with the original script.
extension of file is .bash
How I can lock the script and keep it executable at the same time?
Any suggestions...
Thank you in advance.
You should use:
chmod 755 file.bash
