type coverage/lcov.info | coveralls/bin/coveralls.js
I used above command in appveyor.yml file for generating coverage in coveralls, but there is one problem,Pipe Command is not working in Windows. Please suggest an alternative command for Windows.
What did you expect to happen? Javascript files such as coveralls.js are not an executable file type on Windows. So while pipe does work on Windows, the text to the right of the pipe needs to be an executable command.
Maybe you meant something like this:
jscript coveralls/bin/coveralls.js < coverage/lcov.info

I created executables of a python script (via pyinstaller) for Mac, Windows and Linux. For Linux and Mac, I am running them in the shell since it doesn't have an own interface: just open a shell and type the name of the program.
I am wondering if there is a way to use certain file ending so if the user clicks on the program, it will be automatically executed in the shell or terminal. Alternatively, I would appreciate any other ideas of how to do this.
The way to do this is not to append a certain file ending, but, as pointed out in the comment, make the file executable (chmod +x <file>) and add the magic bytes to the beginning of the file that tell the system how to execute it.
The magic bytes are #! and are followed by the path to executable. So for a python script you would put something like the following at the top of the file:
#!/usr/bin/env python
Okay, now I finally found out the solution to my question. All you have to do to execute the program upon clicking on it in the file browser is to add the ending .command and make it executable
E.g., exampleprogram.command. Clicking on it will execute the program in the shell
So I am not experienced in dealing with a plethora of file types, and I haven't been able to find much info on exactly what .sh files are. Here's what I'm trying to do:
I'm trying to download map data sets which are arranged in tiles that can be downloaded individually: http://daymet.ornl.gov/gridded
In order to download a range of tiles at once, they say to download their script, which eventually leads to daymet-nc-retrieval.sh: https://github.com/daymet/scripts/blob/master/Bash/daymet-nc-retrieval.sh
So, what exactly am I supposed to do with this code? The website doesn't provide further instructions, assuming users know what to do with it. I'm guessing you're supposed to paste the code in to some other unmentioned application for a browser (using Chrome or Firefox in this case)? It almost looks like something that could be pasted in to Firefox/Greasemonkey, but not quite. Just by a quick Google on the file type I haven't been able to get heads or tails on it.
I'm sure there's a simple explanation on what to do with these files out there, but it seems to be buried in plenty of posts where people are already assuming you know what to do with these files. Anyone willing to just simply say what needs to be done from square one after getting to the page with the code to actually implementing it? Thanks.
What is a file with extension .sh?
It is a Bourne shell script. They are used in many variations of UNIX-like operating systems. They have no "language" and are interpreted by your shell (interpreter of terminal commands) or if the first line is in the form
#!/path/to/interpreter
they will use that particular interpreter. Your file has the first line:
#!/bin/bash
and that means that it uses Bourne Again Shell, so called bash. It is for all practical purposes a replacement for good old sh.
Depending upon the interpreter you will have different languages in which the file is written.
Keep in mind, that in UNIX world, it is not the extension of the file that determines what the file is (see "How to execute a shell script" below).
If you come from the world of DOS/Windows, you will be familiar with files that have .bat or .cmd extensions (batch files). They are not similar in content, but are akin in design.
How to execute a shell script
Unlike some unsafe operating systems, *nix does not rely exclusively on extensions to determine what to do with a file. Permissions are also used. This means that if you attempt to run the shell script after downloading it, it will be the same as trying to "run" any text file. The ".sh" extension is there only for your convenience to recognize that file.
You will need to make the file executable. Let's assume that you have downloaded your file as file.sh, you can then run in your terminal:
chmod +x file.sh
chmod is a command for changing file's permissions, +x sets execute permissions (in this case for everybody) and finally you have your file name.
You can also do it in your GUI. Most of the time you can right click on the file and select properties; in XUbuntu the permissions options look like this:
If you do not wish to change the permissions, you can also force the shell to run the command. In the terminal you can run:
bash file.sh
The shell should be the same as in the first line of your script.
How safe is it?
You may find it weird that you must perform another task manually in order to execute a file. But this is partially because of a strong need for security.
Basically when you download and run a bash script, it is the same thing as somebody telling you "run all these commands in sequence on your computer, I promise that the results will be good and safe". Ask yourself if you trust the party that has supplied this file, ask yourself if you are sure that you have downloaded the file from the same place as you thought, maybe even have a glance inside to see if something looks out of place (although that requires that you know something about *nix commands and bash programming).
Unfortunately apart from the warning above I cannot give a step-by-step description of what you should do to prevent evil things from happening with your computer; so just keep in mind that any time you get and run an executable file from someone you're actually saying, "Sure, you can use my computer to do something".
If you open your second link in a browser you'll see the source code:
#!/bin/bash
# Script to download individual .nc files from the ORNL
# Daymet server at: http://daymet.ornl.gov
[...]
# For ranges use {start..end}
# for individul vaules, use: 1 2 3 4
for year in {2002..2003}
do
for tile in {1159..1160}
do wget --limit-rate=3m http://daymet.ornl.gov/thredds/fileServer/allcf/${year}/${tile}_${year}/vp.nc -O ${tile}_${year}_vp.nc
# An example using curl instead of wget
#do curl --limit-rate 3M -o ${tile}_${year}_vp.nc http://daymet.ornl.gov/thredds/fileServer/allcf/${year}/${tile}_${year}/vp.nc
done
done
So it's a bash script. Got Linux?
In any case, the script is nothing but a series of HTTP retrievals. Both wget and curl are available for most operating systems and almost all language have HTTP libraries so it's fairly trivial to rewrite in any other technology. There're also some Windows ports of bash itself (git includes one). Last but not least, Windows 10 now has native support for Linux binaries.
sh files are unix (linux) shell executables files, they are the equivalent (but much more powerful) of bat files on windows.
So you need to run it from a linux console, just typing its name the same you do with bat files on windows.
Typically a .sh file is a shell script which you can execute in a terminal. Specifically, the script you mentioned is a bash script, which you can see if you open the file and look in the first line of the file, which is called the shebang or magic line.
I know this is an old question and I probably won't help, but many Linux distributions(e.g., ubuntu) have a "Live cd/usb" function, so if you really need to run this script, you could try booting your computer into Linux. Just burn a .iso to a flash drive (here's how http://goo.gl/U1wLYA), start your computer with the drive plugged in, and press the F key for boot menu. If you choose "...USB...", you will boot into the OS you just put on the drive.
How do I run .sh scripts?
Give execute permission to your script:
chmod +x /path/to/yourscript.sh
And to run your script:
/path/to/yourscript.sh
Since . refers to the current directory: if yourscript.sh is in the current directory, you can simplify this to:
./yourscript.sh
or with GUI

open the location in terminal then type these commands
1. chmod +x filename.sh
2. ./filename.sh
that's it
I am developing an application on Beaglebone board with Angstrom distrubition fo Linux.I faced an interesting problem.
When I execute :
sh /home/root/Desktop/BBTCP/out/vehicleDetect 192.168.10.29
in terminal it says
/home/root/Desktop/BBTCP/out/vehicleDetect: /home/root/Desktop/BBTCP/out/vehicleDetect: cannot execute binary file
But when i execute
cd /home/root/Desktop/BBTCP/
and
sh out/vehicleDetect 192.168.10.29
it starts working??
What is the reason and why I can't run tha application with first configuration?
I think it is about the difference between ./ and sh. What are the differences?
My first guess would be that one of the folders in the path /home/root/Desktop/BBTCP is a link. If vehicleDetect is a script and it invokes itself recursively, then this link might be confusing it.
If that's not the case, try sh -x /home/root/Desktop/BBTCP/out/vehicleDetect and see what that prints.
Lastly, check what's in the folder /home/root/Desktop/BBTCP. There might be an executable sh in there. If your path contains ., a different shell might be executed.
Seems like /home/root/Desktop/BBTCP/out/vehicleDetect is invoking a binary file (an executable) that was built on a different architecture.
The main difference between sh and ./ is that ./ will attempt to execute the file itself as an executable, whereas sh will do that for you. It could be that there is a weird magic number at the start of the file, but you would expect sh to complain about that.
Best guess though it is a #! line at the start of the file which either contains invalid characters or refers to a strange file. Did you, for example, bring this script file from another operating system (like Windows) that has different line endings? I have seen similar effects when text file scripts have not been converted but just copied. Maybe you downloaded it in a strange format?
Check with od -xc /home/root/Desktop/BBTCP/out/vehicleDetect and look at the first line.
I have a file include some linux command and I want to run in on windows (DOS command).
The command is:
cat tmp/$id/index.html | sed -e 's/ID/$id/g' > a;mv a tmp/$id/index.html
What is the similar command in MS-DOS?
Thank you!
The problem is that natively there is no equivalent command to sed. You have two options from my point of view. Either create a vb script that does what you want (It will not take 1 line though - more like 10-15 I guess), or use something like GnuWin32 that gives you the option to run unix commands in windows terminal.
You could consider using powershell to do approximately the same thing. It supports cat and mv and you can get a sed like equivalent by using %{_ -replace "expression", "replace"}. Details here http://blogs.msdn.com/b/zainnab/archive/2007/07/09/grep-and-sed-with-powershell.aspx
Or consider using a linux like command prompt like bash which should be available through cygwin
I think this is impossible to do in "bare" command line (as you called DOS command), because cat and sed are separate utilities. If you want to port this script from Linux command shell to windows command line, I would advise you to download and install CygWin
DOS itself does not have support for that. You could try with a port of SED for DOS available here. If you can get Powershell, that's an option. Here's an example of using grep/sed with Powershell.
There are many options.
You can try to install cygwin or download and install Git and use Git-bash or add the bin directory to your PATH so you can run this command on your CMD prompt.
There is no such command(s) for MS-DOS.
I'm working on a project where rather than using command line arguments I am supposed to just pipe a file to stdin and pipe output to another file.
ie I need to run something like:
./program < infile.txt > outfile.txt
Is there a way to specify to Eclipse this is the command I want when it is run?
I am running the Eclipse-C/C++ environment.
After using Eclipse for some time, it seems like there is not a straightforward way of doing this. I've resorted to just adding debug code to specify a file and then declare it as an input stream.
