I've compiled an executable from someone else's source code but it will only run if I launch a shell and cd into the right directory and then to ./executable.name. But if i double click the executable I get this error 'There is no application set to open the document'.
Ive tried to do sudo chmod -x executable.name but that doesn't do it.
Does anyone recognise this problem?
I have found the problem was that there was a . in the file name that confused the system. Ive removed the . and it runs fine now

So complete newbie question, but I've googled it and tried all their suggestions and I can't get it to work still :(
Trying to learn about the terminal... so I've created two files on my Desktop - filea.txt, fileb.txt - when I try to run the cd command I get the error, "No such file or directory exists".
I'm in the Desktop so that isn't the problem.
Is there anyone who could please suggest anything I can try?
I appreciate the help, and am completely grateful to anyone who answers - I understand time is valuable.
Thank you!
On an ubuntu to change to Desktop, you should type cd ~/Desktop, now you are in the Desktop directory, now typing ls would should list your files and directories on your desktop. Now you can open your file on a text editing application such as gedit by typing gedit filea.txt, which would open the file filea.txt in the text editor.
If you're trying to change directory to desktop and it's giving you that error, try typing cd .. which goes back one directory, and repeat to go back as far as you can and then try changing directory to desktop again.
Ok so I've been trying to run some things from the command line and I'm having a 'permission denied' problem and then when I 'sudo ./(file.c' I get a 'command not found'. It's weird because other .c files in the same directory work ok.
I've downloaded and installed Xcode and command line tools. Also, I have #include some other things that are also in the same directory.
When I echo $PATH I'm getting this output:
/opt/local/bin:/opt/local/sbin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin
Thanks for any help that could be provided!
You're running sudo ./file.c but file.c looks like the name of a source code file which would usually not be executable. Probably the problem you're having is that you're trying to run something which cannot be run. If you really want to force the computer to run it, you can do chmod +x file.c before trying to run it. But if it is indeed C source code, it won't do anything useful.
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!!
I've been following this tutorial in order to get SimpleOpenNI installed on my mac but I keep getting stuck at installing the OpenNI and NITE components because it requires me to navigate to the folders in Terminal and then run "sudo ./install.sh". I do this and I get this error:
sudo: ./install.sh: command not found
I've installed Command Line Tools in Xcode and everything.
Thanks
The reason why that happens is because the script you are trying to execute needs the right permissions.
Type:
sudo chmod a+x install.sh
and then try again.
In directory of install.sh
prompt$ sh install.sh
first open Terminal, type cd and than drag the map into Terminal and press enter. Now type sudo ./install.sh and it will work. Took me very long to find out. Hope it helps.
.sh scripts should have "\n" line breaks.
"Command not found" also occurs if "\r\n" line breaks are used.
Well at least this is the case on FreeBSD.
You need to run VBoxLinuxAdditions.run as root, not autorun.sh
Once you've inserted the Guest Additions ISO, open Files and open the disc from the sidebar. Then, right-click in the background of the window where autorun.sh is and select
Open in > Terminal
Now you can run the following command to install the Guest Additions:
sudo ./VboxLinuxAdditions.run
I'm a newbie but here is an answer that may help with the sh problem...I am running Armbian on an orange pi prime H5 SBC and I had downloaded and unzipped arduino ide well after 2 hours of searching and trying I hit it ....open the directory where the file you want to open or install is ...now at the top of the directory open a terminal(under file it will say open a terminal here).now the sh filename.sh will work.
I just made a .c file and compiled it with gcc in the terminal on OS X 10.8.2.
My syntax was gcc -o <filename> <sourcefile> and that was fine. Now I see I have an executable and file <filename> tells me as such, but I'm not sure how to actually run it beside double clicking the icon, /lame. When I try running the executable by just typing I get command not found, but I thought it was executable...?
Thank you.
EDIT: I"m so stupid, it was just open <filename>
Unix will only run commands if they are available on the system path, as you can view by the $PATH variable
echo $PATH
Executables located in directories that are not on the path cannot be run unless you specify their full location. So in your case, assuming the executable is in the current directory you are working with, then you can execute it as such
./my-exec
Where my-exec is the name of your program.
To run an executable in mac
1). Move to the path of the file:
cd/PATH_OF_THE_FILE
2). Run the following command to set the file's executable bit using the chmod command:
chmod +x ./NAME_OF_THE_FILE
3). Run the following command to execute the file:
./NAME_OF_THE_FILE
Once you have run these commands, going ahead you just have to run command 3, while in the files path.
