So I'm getting some pretty strange behaviour when I try to use an Automator service to open new emacs (GNU Version 25.2 with spacemacs) buffers.
In my terminal, the command emacsclient -a '' -c works as expected, opening a new buffer through emacsclient. However, when I make a service in Automator which simply runs a (/bin/bash) shell script:
emacsclient -a '' -c
I get an error message:
The action “Run Shell Script” encountered an error: “emacsclient: could not get terminal name”
On suspicions that this was due to Automator not using some default PATH variable, I tried the following instead:
PATH=/usr/local/bin:$PATH
emacsclient -c
which produced the same error as before.
Next I tried
PATH=/usr/bin:/usr/local/bin export PATH;
emacsclient -c
which produced a different error message:
The action “Run Shell Script” encountered an error: “emacsclient: invalid option -- c
Try `emacsclient --help' for more information”
however why I try that script in my terminal it also gives a similar error which doesn't make much sense to me.
If anyone has suggestions for how to fix this I'd really appreciate it.
The problem is the shell script is running an old version of emacsclient in /usr/bin you need to run the one in Emacs.app/Contents/MacOS/bin/emacsclient. Delete the PATH line and you can use a solution listed here for running emacsclient inside automator Running a macOS service for open with emacs failed with "emacsclient: could not get terminal name mac"

When I run my code in VS Code, I get this message after every user interface input
The default interactive shell is now zsh.
To update your account to use zsh, please run chsh -s /bin/zsh.
What can I do to use zsh and/or keep this messsage from appearing?
If you are using MAC, Apple has changed the default Interactive Shell from macOS Catalina.
But your Shell still could be bash.
if you want to change it to zsh, just run the following command in your terminal.
chsh -s /bin/zsh

I have been trying to pip install psycopg2 for some time now
I have just updated to python 3.7.4, before this problem started.
To set my path to a specific python version I used the code below.
nano .bash_profile
I thought that it would now be easy for my system to identify the path of the newly installed python, as to enable it to install psycopg2. Then the below started happening.
The second line of system terminal or python terminal is now always showing:
-bash: zzzzz#: command not found on my terminal
No matter what I type on my terminal, I am always getting command not found
This would mean you literally have "zzzzz" somewhere in the bash_profile. Bash is seeing "zzzzz" as just another command to run at startup like the rest of the profile script. As there is nothing in your PATH matching that string, bash reports the issue back to you.
Either remove the extra line from your .bash_profile. OR use a terribly wasteful work-around!
ln -s /bin/true /bin/zzzzz
This will create a symbolic link to the "true" binary (all it ever does is return true) from zzzzz. Now bash can find zzzzz and run it during start up, which does nothing. No more error and an absurd work around. You should fix the file.
I am having a strange issue. I have written a script which is basically running a perl script in remote server using ssh.
This script is working fine but after completion of the above operation it will ask user to choose the next operation.
it is showing the options in the command prompt but while I am giving any input it is not showing in the screen even after hitting enter also it remain same.
I am not getting what is the exact issue, but it seems there is some issue with the ssh command because if I am commenting out the ssh command it is working fine.
OPERATION:
print "1: run the script in remote server \n2: Exit\n\nEnter your choice:";
my $input=<STDIN>;
chomp($input);
..........
sub run_script()
{
my $com="sshg3.exe server -q --user=user --password=pass -exec script >/dev/null";
system("$com");
goto OPERATION;
}
after completing this ssh script it is showing in screen:
1: run remote script
2: exit
Enter your choice:
but while I am giving any input it is not displaying in the screen until and unless I am exiting it using crtl C.
Please can anyone help what might be the issue here ?
One of the classic gotchas with ssh is this - that it normally runs interactively, and as such will attach STDIN by default.
This can result in STDIN being consumed by ssh rather than your script.
Try it with ssh -n instead.
You can redirect the output in command prompt if -n option is not available for you.
try this one it might work for you.
system("$com />null");
As per https://support.ssh.com/manuals/client-user/62/sshg3.html there is an option for redirecting input use --dev-null (*nix) or --null (Windows).
-n, --dev-null (Unix), -n, --null (Windows)
Redirects input from /dev/null (Unix) and from NUL (Windows).
I use an emacs daemon to preserve my emacs session even if I have to reboot the machine that I run my X server on or if I want to access the same session from a different machine. This works very well but when restoring a session I'd quite like to just run "emacsclient --create-frame --no-wait" to connect to the daemon without opening a new file. It won't let me get away without specifying a filename.
I've tried using --eval to execute a function rather than open a file but the window just goes away when the evaluation is complete.
(Emacs 23.1 via backports on Debian GNU/Linux 5.0.)
From the help provided by emacsclient, you have a few options. First, is the one mentioned already which is emacsclient -c. That will try to create a frame associated with the emacs daemon. The advantage to this is that if DISPLAY is not set, then it will open emacs in the terminal.
Which brings us to the next best option (especially if you are logging in remotely): emacsclient -t which forces emacs to open up in terminal mode even if DISPLAY is set.
Also keep in mind that you can set the display from the command-line as well. I use this often when logging in remotely from VNC. The full command would be emacsclient -d DISPLAY -c
emacsclient -c works for me.
emacsclient -n -e "(make-frame)"
The -n flag means that the emacsclient doesn't wait, and the emacs instance doesn't destroy the frame.
If you are using emacs from the command line, you might also want to consider emacsclient -t
I have script lets say:
C:\foo.bsh
I want to be able to run this command via the windows run command:
Start -> Run
Windows Key + R
and type something small like 'foo' and hitting return.
However, I do not want a cmd prompt to be visible. This script does some preprocessing for an IDE. I do not want the cmd prompt to be open for the lifetime of the IDE process.
I have tried:
1) Creating a bat file with the following contents:
c:\cygwin\bin\bash --login "C:\foo.bsh" (this fails because it keeps a cmd open)
2) Converting the above bat file to an exe using bat_2_exe_converter (does not make the cmd silent)
thoughts?
EDIT: The solution so far suggests something to type from an actual cygwin shell. I am trying to get a faster solution by having something short I can type in the Windows run command. Also, the nohup command; exit doesn't automatically kill the box - however I can manually kill it without killing the IDE process. The run command accepts shortcuts (.lnk's), bat's, exe's.
Try the run.exe command of cygwin. It is a big install, a complete unix environment for your Windows machine. Suppose you installed it at c:\cygwin\.
No mystery, just run c:\cygwin\bin\run.exe <your command here> and you will have your no dos window execution.
You can run it from any DOS window (run cmd.exe from the start menu). You don't need to run it from cygwin.
To make it easier, append C:\cygwin\bin to your %PATH% env var (My Computer → Properties → Advanced → Environment Variables) (Kudos to Felipe Alvarez comment).
Now you can just type
c:\cygwin\bin\run.exe "C:\foo.bsh"
You must create a link in your Start Menu with this command so will be able to run it with Win-R.
Here is the man page of the runcommand:
$ man run
RUN(1) run 1.3.0 RUN(1)
NAME
run - start programs with hidden console window
SYNOPSIS
run [ -p path ] command [ -wait ] arguments
runcommand [ -p path ] [ -wait ] arguments
DESCRIPTION
Windows programs are either GUI programs or console programs. When
started console programs will either attach to an existing console
or create a new one. GUI programs can never attach to an exiting con‐
sole. There is no way to attach to an existing console but hide it if
started as GUI program.
run will do this for you. It works as intermediate and starts a pro‐
gram but makes the console window hidden.
With -p path you can add path to the PATH environment variable.
Issuing -wait as first program argument will make run wait for program
completition, otherwise it returns immediately.
The second variant is for creating wrappers. If the executable is
named runcommand (eg runemacs), run will try to start the program (eg
emacs).
EXAMPLES
run -p /usr/X11R6/bin xterm
run emacs -wait
runemacs -wait
run make -wait

You can use either...
c:\cygwin\bin\bash -l /path/to/script_to_interpret.sh
...or...
c:\cygwin\bin\bash -l -c /path/to/executable_script.sh
Note: the -l flag tell bash to "act as if it had been directly invoked by login" and use Bash Startup Files. This is important in that it sets your $PATH and other things you rely on when you launch a cygwin terminal. If you don't include -l or --login you will get "command not found" when you try to call anything except of a bash builtin.
The difference between the 2 is like the difference between doing...
bash script_to_interpret.sh
...and...
./executable_script.sh
...in *nix. The former interprets the script using bash. The latter executes the script (only if it has chmod +x executable_script.sh) and interprets it according to its "shebang" line. The latter method is also what you want to do if your executable is not a script at all, like a *nix binary compiled from source.)
It has been bugging me for a while I couldn't find the solution for this, but I finally got the right mix together.
You can simply do the following if you have cygwin on your PATH:
run bash test.js
If cygwin is not on your path, you can do this:
c:\cygwin\bin\run.exe -p /bin bash test.js
If you are looking for more control over the created window (maximize, etc) it looks like you can use cygstart also.

As the terminal can't close while your script is still running, try the command:
"nohup C:\foo.bsh; exit"
This way your script will be backgrounded and detached from the terminal, and it should exit quickly so the terminal goes away. I think that the window may still 'flash' with this approach, but the results should be better than what you're getting.
I'm running Cygwin64 and the xwin server link points to:
C:\cygwin64\bin\run.exe /usr/bin/bash.exe -l -c /usr/bin/startxwin.exe
This creates an icon AND a notification on the taskbar. I don't like that. The icon is rather useless, the notification has all your menu options from .XWinrc.
So... I wrote a .vbs script to silently run this command and make the icon go away:
Set objShell = CreateObject("WScript.Shell")
objShell.Run("C:\cygwin64\bin\run.exe /usr/bin/bash.exe -l -c /usr/bin/startxwin.exe"), 0
Another imperfect possibility is to run the script via a shortcut and set the shortcut's Run option to "minimized".
Go to the directory where you have installed cygwin(on my machine it is c:/cygwin64/bin)
Once there simply type "bash.exe"
