I'm trying to use a shell script to have mc cd into some directories,
be them virtualfs directories (e.g. ftp, ssh) or local directories. How should I do that?
mc allows you only to launch a new instance with requested path open in one of the panels. For local files you can just provide the directory as argument:
mc somedirectory
If you prepend sh:// you can open remote directories on other machines as well:
mc sh://user#host/somedirectory
This works from the command line as well as from shell scripts.

I have a instance where I have some Flask web app. In order the app to start when the VM is booted I have included a startup script:
#!/bin/sh
cd documentai_webapp
cd docai_webapp_instance_gcp
sudo python3 server.py
However, this is not at all executed, anyone can help me?thanks!
PD: When I execute this script manually within the VM it works perfectly fine
As context it is necessary contemplate:
For Linux startup scripts, you can use bash or non-bash file. To use a non-bash file, designate the interpreter by adding a #! to the top of the file. For example, to use a Python 3 startup script, add #! /usr/bin/python3 to the top of the file.
If you specify a startup script by using one of the procedures in this document, Compute Engine does the following:
Copies the startup script to the VM
Sets run permissions on the startup script
Runs the startup script as the root user when the VM boots (missing step from #Andoni)
For information about the various tasks related to startup scripts and when to perform each one, see the Overview.
I M New to Django, Whenever I open my project, everyday i type CMD to activate virtual env then, to open local server i use runserver, but I want to open my local host by using single command. Is there any way to do that?
If you want to run command using shell script you have to open text editor and write your desired command. then save it as .bat file. It will create a executable file and simply use double click to run it. if you have multiple command use '&' between them.
Example
cd your directory &
python manage.py runserver
I am trying to upload a file to a remote server using the SCP task. I have OpenSSH configured on the remote server in question, and I am using an Amazon EC2 instance running Windows Server 2008 R2 with Cygwin to run the Bamboo build server.
My question is regarding finding the directory I wish to use. I want to upload the entire contents of C:\doc using SCP. The documentation notes that I must use the local path relative to the Bamboo working directory rather than an absolute directory name.
I found by running pwd during the build plan that the working directory is /cygdrive/c/build-dir/CDP-DOC-JOB1. So to get to doc, I can run cd ../../doc. However, when I set my working directory under the SCP configuration as ../../doc/** (using this pattern matching guide), I get the message There were no files to upload. in the log.
C:\doc contains subfolders as well as a textfile in the root directory.
Here is my SCP task configuration:
Here is a look from cygwin at my directory:
You may add a first "script" task running a Windows shell, that copies everything from C:\doc to some local directory, and then run the scp task to copy the content of this new directory onto your remote server
mkdir doc
xcopy c:\doc .\doc /E /F
Then the pattern for copy should be /doc/**
I am stuck at using Amazon EC2 CLI.
I have downloaded the Command Line Tools from
http://aws.amazon.com/developertools/351.
I placed the bin and lib folder into my Amazon project folder: /Users/Invictus/EC2
I downloaded the cert-xxxx.pem and pk-xxx.pem into the same folder.
Created a .bash_profile in the same folder.
I tried to execute ec2-describe-images -o amazon after I moved to cd /Users/Invictus/EC2.
The system does not recognise the command: command not found.
If I try to execute the same command inside the bin folder, the result is the same.
My .bash_profile:
export EC2_HOME=~/.EC2
export PATH=$PATH:$EC2_HOME/bin
export EC2_PRIVATE_KEY=`ls $EC2_HOME/pk-*.pem`
export EC2_CERT=`ls $EC2_HOME/cert-*.pem`
export JAVA_HOME=/System/Library/Frameworks/JavaVM.framework/Home/
Where did I make a mistake?
My aim is to connect to the launched instance and be able to execute commands there from my local machine.
I have Java installed.
The newer AWS Unified CLI Tools is much, much easier to set up. All you need is Python, which comes built-in to every Mac.
Here are a few things I can think of:
Your .bash_profile should be in /Users/Invictus/ , not /Users/Invictus/EC2. Move it to your home directory and log off and log back in (or restart your machine) and see if it picks up the right path.
Instead of ec2-describe-images, can you run it as "./ec2-describe-images" - does that work? If not, can you check the permissions on that script?
I'm trying to come up with some sensible solution for a build written using SCons, which relies on quite a lot of applications to be accessible in a Unix-like way, using Unix-like paths etc. However, when I'm trying to use SCons plugin, or Git plugin in Jenkins, it tries to invoke the plugins using something like cmd /c git.exe - and this will certainly fail, because Git was installed using Cygwin and is only known in Cygwin shell, but not in CMD. But even if I could make git and the rest available to cmd.exe, other problems arise: the Cygwin version of Git expects paths to have forward slashes and treats backward slashes as escape characters. Idiotic Windows file-system related issues kick in too (I can't give Jenkins permissions to delete my own files!).
So, is there a way to somehow make Jenkins only use Cygwin shell, and never cmd.exe? Or should I be prepared to run some Linux in a VM to have this handled?
You could configure Jenkins to execute the cygwin command with the specific shell command, as follows:
c:\cygwin\bin\mintty --hold always --exec /cygdrive/c/path/to/bash/script.sh
Where script.sh will execute all the commands needed for the Jenkins execution.
Just for the record here's what I ended up doing:
Added a user SYSTEM to Cygwin, mkpasswd -u SYSTEM
Edited /etc/passwd by adding the newly created user's home directory to the record. Now it looks something like the below:
SYSTEM:*:18:544:,S-1-5-18:/home/SYSTEM:
Copied my own user's configuration settings such as .netrc, .ssh and so on into the SYSTEM home. Then, from Windows Explorer, through an array of popups I've claimed ownership of all of these files to SYSTEM user. One by one! I love Microsoft!
In Jenkins I now run a wrapper for my build that sets some other environment variables etc. by calling c:\cygwin\bin\bash --login -i /path/to/script/script
Gave it up because of other difficulties in configuration and made Jenkins service run under my user rather then SYSTEM. Here's a blog post on how to do it: http://antagonisticpleiotropy.blogspot.co.il/2012/08/running-jenkins-in-windows-with-regular.html but, basically, you need to open Windows services, then find Jenkins service, select it's properties, go to "Logon" tab and change the user to the "this user".
One way to do this is to start your "execute shell" build steps with
#!c:\cygwin\bin\bash --login
The trick is of course that it resets your current directory so you need to
cd `cygpath $WORKSPACE`
to get back to the workspace.
Adding to thon56's good answer: this is helpful: "set -ex"
#!c:\cygwin\bin\bash --login
cd `cygpath $WORKSPACE`
set -ex
Details:
-e to exit on error. This is important if you want your jobs to fail on error.
-x to echo command to the screen, if desired.
You can also use #!c:\cygwin\bin\bash --login -ex, but that echos a lot of login steps that you most likely don't care to see.
