I widely use Unix/Posix like commands in my daily activities.
I have only Windows environments.
For that reason I use utility called MobaXterm which is built on top of Cygwin and allow me to use utilities like awk, sed, Grep and etc.
I noticed that Power shell on my PC works significantly faster than MobaXterm hence I want to use it from inside the powershell.
E.g. instead of using poweshell ‘Select-String’ I want to use Cygwin’grep’
How should I do it? Could I change the path to MobaXterm bin directory to make powershell aware of it? Or something similar?
Note: I do not have admin privilege on my PC
Appreciate your help

I am been currently studying AWS, and my online instructor uses "Windows PowerShell", however, I have always used "Hyper Terminal" for MERN stack. What is the difference between the two, and what sets this two apart from the Command Prompt?
Here is the simple answer:
PowerShell Preview replaced PowerShell, and PowerShell replaced Command Prompt (CMD).
Windows Terminal is an application that simply provides tabs to open multiple instances of PowerShell (Preview or legacy) and Command Prompt, as well as Azure cloud shell.
In Linux. you'll often hear the terms 'terminal' and 'console' used interchangeably, but they mean the same in Linux as they do in Windows. That is, console is the Linux alternative to the DOS style command prompt.
I am not familiar with Hyper Terminal but I see there are terminal emulators online that go by that name therefore I assume you may be using a third party terminal emulator.
PowerShell is a newer shell and also happens to be an object-oriented scripting language.
As far as Windows shells go, I can use PowerShell to do anything I used to do with CMD. Generally speaking, I would say PowerShell really shines when it comes to Windows System administration which is my primary use for it and it saves me a great deal of time.
As far as terminal emulators go, I feel the default terminals for both PowerShell and CMD are pretty much the same and are very lacking compared to 3rd party offerings or even the default terminal that comes in any modern Linux OS.
For a free "Microsoft" alternative to replace your default terminal, I would recommend the open-source "Windows Terminal" app. The addition of tabs, panes, zoom function, easy to read text, and easy ways to start different shells (such and CMD or PowerShell) or even start a WSL session with your choice of Linux OS is a major improvement to the default Windows terminal app.
Usually, on Windows, I use PowerShell (default shell) to call a Bazel command such as bazel build. As far as I understand Bazel makes use of MSYS2 to call and execute commands such as curl, zip or git for instance. Therefore, I wonder if I should use the MSYS2 bash terminal instead of PowerShell. Can there be any problems when using Powershell instead of the MSYS2 bash terminal? Or doesn’t it matter?
As its mentioned here by developers of bazel, using MSYS or MSYS2 is the best choice. Personally I prefer MSYS* over cmd or PowerShell for any thing.
In the current master there was recently an update of the documentation exactly about this issue:
As of 2020-01-15, we do not recommend running Bazel from bash – either
from MSYS2 shell, or Git Bash, or Cygwin, or any other Bash variant.
While Bazel may work for most use cases, some things are broken, like
interrupting the build with Ctrl+C from MSYS2). Also, if you choose to
run under MSYS2, you need to disable MSYS2’s automatic path
conversion, otherwise MSYS will convert command line arguments that
look like Unix paths (e.g. //foo:bar) into Windows paths. See this
StackOverflow answer for details.
I just installed vim. It's awesome. From PowerShell, I want to be able to launch it both via typing vim and by typing vim someFile.txt.
I can already open vim through the run dialog. Further, it's already in my system PATH. What must I do to launch it from PowerShell?
If it's already in the path, it should work.
But you can, alternatively, use an alias via New-Alias. If you add that to your profile, it will load every time.
To see how the run box behaves differently from powershell, and how you might get around that, see my answer here:
Run a program by name from PowerShell (similarly to the run box)
is there a posibility to make eclipse PyDev use a remote Python interpreter?
I would like to do this, as the Linux Server I want to connect to has several optimization solvers (CPLEX, GUROBI etc.) running, that my script uses.
Currently I use eclipse locally to write the scripts, then copy all the files to the remote machine, log in using ssh and execute the scripts there with "python script.py".
Instead I hope to click the "run" button and just have everything executed within my eclipse IDE.
Thanks
Unfortunately no. You can remotely connect to your Linux server via Remote System Explorer (RSE). But can't use it as a remote interpreter. I use Pycharm. You can use the free Community Edition or the Professional Edition for which you have to pay for it. It is not that expensive and it has been working great for me.
As Adel says, this is probably not possible with the Remote System Explorer, or the normal Run button,
but you can automate the process you currently use. I had to do this for a few weeks when the fan was broken
in my laptop, and doing any significant computation there made it overheat and poweroff, so I just ran
everything on my work machine.
You can use the External Tools mechanism to run a short script that syncs your code to the remote server,
runs your script, then syncs back any output files to your local machine. My script looks like this,
is stored in $HOME/bin/runremote.sh, and is executable (chmod +x runremote.sh)
fp="$1" # Local path to the script we want to run--for now,
# this is the only command I pass in from Eclipse, but you could add others if so inclined.
# My home directory is a little different on my local machine than on the remote,
# but otherwise things are in the same place. Adjust as needed.
fp=`python -c "print '$fp'.replace('/home/tsbertalan', '/home/oakridge/bertalan')"`
# Run the synchronization. I use Unison, but you could use something else,
# like two calls to rsync, or a series of scp commands.
reposync >/dev/null # The redirection assumes your sync command will print errors properly on stderr.
cd='cd '`dirname $fp`
# I use a virtual environment on the remote server, since I don't have root access to install
# packages globally. But this could be any set-up command you want to run on the remote.
# A good alternative would be `source $HOME/.profile` or `~/.bashrc`.
act='source /home/oakridge/bertalan/bin/activate'
fname="`basename $fp`"
cmd="$act ; $cd ; python $fname"
# Run the command remotely. The -X forwards X11 windows, so you can see your Matplotlib plots.
# One difficulty with this method is that you might not see all your output just as it is created.
ssh bertalan#remote.server.edu -X "$cmd"
sleep 1
# My synchronization script is bidirectional, but you could just use rsync with the arguments flipped.
reposync >/dev/null
If you don't use linux or OSX locally, you'll probably have to use MinGW or Cygwin or whatever to get
this working. Or, since you appear to have a working Python interpreter, you could write an
equivalent script in Python, make it executable (by the file properties dialog in Explorer, I think),
and add a #!/path/to/python line at the top. I don't use Windows regularly, so I can't really help with that.
To use this in Eclipse, go to Run > External Tools > External Tools Configurations.... Add a new tools
whose Location is the path to your script, and whose first Argument is ${resource_loc}.
You can then use it with Run > External Tools > [first item], or bind it to a keyboard shortcut (I used F12)
by going to Windows > Preferences > Keys, and searching for "Run Last Launched External Tool". Presumably you'll
have to go through the menus first to make this the "Last Launched" external tool.
Is it possible to build a Perl wrapper around the GNOME terminal which would help me to pass commands to it and also capture the ouputs on the terminal?
You may be able to use Gnome2::Vte (I don't know how maintained / bug-free it is, YMMV) to create your own gnome-terminal alike (gnome terminal uses libvte) instead of wrapping the terminal.
