First I start up eshell then I enter the command cd /plink:<user>#<host>:/home/
then I get this error message

I am trying to connect with plink (which is in my path), also after going through the *Messages* buffer I found this.
Couldn't find local shell prompt for (C:\Windows\system32\cmd.exe)
I'm 90% sure that this is because the cmd has been disabled on my machine, because when I try the same setup on a different computer, where I know the cmd is enabled, everything works.
I've modify my .emacs file to have
(require 'tramp)
(set 'tramp-encoding-shell "C:/Windows/System32/WindowsPowershell/v1.0/powershell.exe")
(set 'tramp-encoding-command-switch "-Command")
I get different results, however the results appear to be scrambled nonsense (the third line looks like it could be a prompt, the \ and > characters are in the correct places...).
I managed to dig up a pretty good description of what tramp-encoding-shell is, there's also a related SO question, and here is the tramp-encoding-shell source/documentation on github.
Update
Here is what my screen looks like after trying to unsuccessfully open a plink connection with powershell set as the tramp-encoding-shell.
So I dont know TRAMP but the explanation of what you get is that Windows PowerShell send you back unicode (UTF16), each character is 16 bits in this case the letter an a zero, plus the fact that the End Of Line is carriage return / line feed (0xa, Oxd).
Now for "emacs could not find local shell prompt for PowerShell" error according to TRAMP documentation #Michael Albinus advice seems to be promising.
6.4.2 Running shell on a remote host
Calling M-x shell in a buffer related to a remote host runs the local shell as defined in shell-file-name. This might be also a valid file name for a shell to be applied on the remote host, but it will fail at least when your local and remote hosts belong to different system types, like ‘windows-nt’ and ‘gnu/linux’.
You must set the variable explicit-shell-file-name to the shell file name on the remote host, in order to start that shell on the remote host.
6.4.6 Running remote processes on Windows hosts
With the help of the winexe it is possible tu run processes on a remote Windows host. TRAMP has implemented this for process-file and start-file-process.
The variable tramp-smb-winexe-program must contain the file name of your local winexe command. On the remote host, Powershell V2.0 must be installed; it is used to run the remote process.
In order to open a remote shell on the Windows host via M-x shell, you must set the variables explicit-shell-file-name and explicit-*-args. If you want, for example, run cmd, you must set:
(setq explicit-shell-file-name "cmd"
explicit-cmd-args '("/q"))
In case of running powershell as remote shell, the settings are
(setq explicit-shell-file-name "powershell"
explicit-powershell-args '("-file" "-"))

I want to run a bash script on a mac remotely from a batch script on a windows machine. On Windows I have this:
#echo off
echo bash /applications/snowflake/table-updater/test2.sh; exit>tmp_file
putty -ssh User#remote_machine -pw password -m tmp_file
And here is test2.sh on the remote machine
#!/bin/bash
# test2.sh
#
#
7za x table-apps.zip -y -o/Applications/snowflake/applications
When the batch file runs it logs in successfully, but for some reason fails to run the bash file. However the bash file runs fine from mac terminal, where it unzips the files perfectly. What could be happening here?
Please note test2.sh is actually in Applications/snowflake/table-updater as specified in the batch file. And the tmp file does write fine as well. My aim is to have a script to access a further 10 remote machines with the same directory structure.
Thanks in advance
The standard program which resembles the scriptable Unix command ssh in the PuTTy suite is called plink, and would probably be the recommended tool here. The putty program adds a substantial terminal emulation layer which is unnecessary for noninteractive scripting (drawing of terminal windows, managing their layout, cursor addressing, fonts, etc) and it lacks the simple feature to specify a command directly as an argument.
plink user#remote_machine -pw password /Applications/snowflake/table-updater/test2.sh
From your comments, it appears that the problem is actually in your script, not in how you are connecting. If you get 7za: command not found your script is being executed successfully, but fails because of a PATH problem.
At the prompt, any command you execute will receive a copy of your interactive environment. A self-sufficient script should take care to set up the environment for itself if it needs resources from non-standard locations. In your case, I would add the following before the 7za invocation:
PATH=$PATH:/Applications/snowflake/table-updater
which augments the standard PATH with the location where you apparently have 7za installed. (Any standard installation will take precedence, because we are adding the nonstandard directory at the end of the PATH -- add in front if you want the opposite behavior.)
In the general case, if there are other settings in your interactive .bashrc (or similar shell startup file) which needs to be set up in order for the script to work, the script needs to set this up one way or another. For troubleshooting, a quick and dirty fix is to add . /Users/you/.bashrc at the top of the script (where /Users/you should obviously be replaced with the real path to your home directory); but for proper operation, the script itself should contain the code it needs, and mustn't depend on an individual user's personal settings file (which could change without notice anyway).
I am working on Windows 7 (logged in as session no.1), my Jenkins CI is running as windows service in session 0.
My problem is.. I want to open an Excel file through Jenkins CI in session 0, but want to display its GUI on session 1.
I know that session 0 is isolated in Windows 7, but is it possible to run a process in session 0 and then output in another session? please help.
Edit:
Took a little trial and error, but this is what finally worked for me (Windows 7 64-bit).

We only need psexec.exe, but you can extract everything. Extract to some location accessible by Jenkins, preferably without spaces in the path.
Open elevated command prompt: type cmd into Start's quicksearch, right click cmd.exe, select Run as Administrator.
Type C:\path\to\psexec.exe -accepteula and press enter.
Type C:\path\to\psexec.exe -i 1 cmd and press enter. (If you see a command prompt appear, all is good, close it now)
In Job configuration, configure Execute Windows Batch command step
Write the following:
C:\path\to\psexec.exe -accepteula && C:\path\to\psexec.exe -i 1 cmd /c start C:\PROGRA~2\MICROSO~1\path\to\excel.exe
Where:
C:\path\to is your full path to psexec.exe, unless it is in your %path%
-i 1 is the session ID that you want to launch in.
C:\PROGRA~2\MICROSO~1\path\to is your full path to excel.exe without spaces. Since most Office installations are going to be under paths with spaces, like "Program Files (x86), you have to figure out the short path, or place it somewhere without spaces.
Having excel.exe under %path% and working from regular command line was not enough.
A little explanation for those that care:
psexec needs to install a services first. For that, it needs to be run from elevated command prompt for the first time. This is a one-time installation step.
To make psexec work, you need to accept the EULA prompt. This is done per session/user. So even if you run psexec -accepteula in your command prompt, it doesn't help when Jenkins service (running as Local System in session 0) tries to use it. Therefore, you have to place that into the Jenkins job, along with the command. Technically, it only needs to be there once, and can be removed afterwards, but it definitely doesn't hurt to keep it there.
I've used cmd /k and running this command from my local cmd prompt to debug. This is what made me realize I couldn't find a way to escape the spaces (tried various quoting), so had to resort to short file names. Note that short file names are not required, this is just to escape spaces.
no its not-
plus any UI interactions requires you to run Jenkins as Java web start rather than a service or you can not interact with UI elements.
I've been trying to install the 64bit version of PostgreSQL 9.2 for Windows on my machine (Windows 7 64bit) and get this error:
The environment variable COMPSPEC does not seem to point to the cmd.exe or there is a trailing semi colon present.
I've installed it as Administrator.
I disabled the antivirus (Microsoft Security Essentials) and the firewall.
Running:
"%COMSPEC%" /C "echo test ok"
returned test ok
I've checked my System Environment Variables for trailing semi colon and I couldn't find any.
I then installed the 32bit version and managed to get to the end of the install with a different error message stating: Problem running post-install step. Installation may not complete correctly Error reading the C:\Program Files (x86)\PostgreSQL\9.2\data\postgresql.conf but there is no postgresql.conf file in that directory. It did install the application and when I try to connect the server with the red X on it it says fail at the bottom and it won't connect after I type in my password.
How can I connect to this server connection?
ComSpec is a generic error message for any installation failure.
Identifying the problem
Navigate to below path
c:\Users\XXXXXX\AppData\Local\Temp
Open 'bitrock_installer_XXXX.log'
Check, if you are getting below error:
Script stderr:
'"C:\Users\XXXXX\AppData\Local\Temp\POSTGR~1\TEMP_C~1.BAT"' is not recognized as an internal or external command, operable program or batch file.
Error running
C:\Users\XXXXX\AppData\Local\Temp/postgresql_installer_47b21c4ea1/temp_check_comspec.bat :
'"C:\Users\XXXXX\AppData\Local\Temp\POSTGR~1\TEMP_C~1.BAT"' is not recognized as an internal or external command,
operable program or batch file.
This is a problem with '8.3 file names and directories' (e.g. '\Postgres Install' -> '\POSTGR~1')
Microsoft article on disabling 8.3 file names and directories: https://support.microsoft.com/en-gb/kb/121007
Solution:
Open command prompt in admin mode
Execute following command to change the format based on your drive or all drives
Sample commands:
fsutil 8dot3name set 1" - disable 8dot3 name creation on all volumes
fsutil 8dot3name set C: 1" - disable 8dot3 name creation on c:
Execute the installation as a user having admin privileges
After install, consider resetting the 8dot3name setting to default (2) to avoid unintended consequences
Hope it solves the problem!
Very easy fix:
Just open Advanced System Settings in Control Panel and create a new System Variable( in the System Variable instead of User Variable section).
In the variable name, enter ComSpec and then in the variable value , enter C:\Windows\system32\cmd.exe.
Alternative fix:
If you have already the ComSpec variable in the System Variable section, remove the ;at the end of it this should fix it.
It's not COMPSPEC it's just COMSPEC. Please show the output of:
echo %COMSPEC%
Note that COMSPEC could be set to something different in the Administrator account you're running the installer as. I'm not sure how to find that out, but it might appear in the PostgreSQL installer log, so please upload that and link to it in your post. See Reporting an installation error for info on where to get the installer log.
See the PostgreSQL for Windows FAQ entry Check the COMSPEC environment variable.
Here's a report I made suggesting that the installer should test for this explicitly and here's my blog post on the topic.
I got the same problem, and i found in the log:
Script stderr:
'C:\Users\S300' is not recognized as an internal or external command,
operable program or batch file.
Error running C:\Users\S300 (i5)\AppData\Local\Temp/postgresql_installer_56caeadbd6/temp_check_comspec.bat : 'C:\Users\S300' is not recognized as an internal or external command,
operable program or batch file.
I change in User Variables TEMP to D:\TEMP and TMP to D:\TEMP.
And Solved My Problem.
In my case , the Installer was in %USERPROFILE%\DownloadsP{ Windows download folder}, I moved the installer to desktop and ran again. weird it worked lol.
I had a similar problem. After installation, the data folder contained no postgres.conf file. It only contained a single folder named "pg_log".
I described the solution that I used here: Postgres Installation Error reading file postgresql.conf
Basically, it would be helpful to check if the user has full permissions for the postgres folder, and run "init_db" and "pg_ctl start" commands again. If the path contains a space character, try using a relative path for the pg_ctl data folder argument.
I'm running Windows Server 2003 R2, and I have been unable to resolve this problem with the installer, so I resorted to using the binary PostgreSQL package. Hopefully this will be an alternative for others who do not want to perform an OS reinstall.
First, some background (hopefully useful to the developers)
It started out with the postgres service failing to start (the server had been running reliably for over a year). I assumed it was a corrupted PostgreSQL installation, so I uninstalled and attempted to reinstall. I encountered the following error:
There has been an error.
The environment variable COMSPEC does not seem to point to the cmd.exe or there is a trailing semicolon present.
Please fix this variable and restart installation.
However, the COMSPEC variable is set properly, verified with:
echo %COMSPEC%
C:\WINDOWS\system32\cmd.exe
and:
"%COMSPEC%" /C "echo test ok"
test ok
Since this is Windows Server 2003, there is no UCA wrapper around the Administrator account, so that is not causing the problem.
Manual Installation
NET USER postgres /ADD
C:\pgsql\bin\initdb.exe -U postgres -A password -E utf8 -W -D C:\pgsql\data
runas /user:postgres "C:\pgsql\bin\pg_ctl -D C:/pgsql/data -l C:/pgsql/logfile.txt start"
just do it run as administrator and change the environment system variable
like create a new variable 'ComSpec' and value type 'C:\Windows\system32\cmd.exe'.
If the installer exe is on a network share that mapped drive might actually not be accessible to the installer as it runs as administrator. This can often happen in some virtual machine arrangements such as running windows in a parallels VM. Copy the installer to a local drive first and you won't have a problem.
What worked for me after trying to enter the commandline given her in cmd.exe
I found it was named cmd1.exe in system32.. so i copied the file and renamed it as cmd.exe and installation finished
Open Environment Variables, you can do this on Windows 7 by typing environment variables in the Search program and files bar when pressing the start button at the bottom left of the desktop. And create a new System Variable(in the 'System Variable' instead of 'User Variable' section).
In the variable name, enter ComSpec and then in the variable value , enter C:\Windows\system32\cmd.exe.
That's all. Hope it works!
Alternative fix:
If you already got the ComSpec variable in the System Variable section, remove the ; at the end of it this should fix it.
First find the path to cmd.exe(mostly it is C:\Windows\System32\cmd.exe).
Go to the enviornment variable and add this path to system variable path.And also create new variable in user variable called ComSpec and add this path as value. And you are ready to go.
I am trying to use Emacs 24.2 with Tramp on windows 7 to remotely edit files on a linux server. I installed the Putty suit program and OpenSSH. I also placed the plink.exe in the putty suit into the bin folder under the emacs 24 folder, and added the folder emacs24/bin into the PATH environment variable.
However, when I try to access the remote file from emacs with the command in the minibuffer: /username#host:filename, I get the following error message from emacs: plink is not recognized as an internal or external command. It seems that emacs cannot find the plink program. But, when I try to run plink in windows cmd, it can find the plink program. Also, I can ssh to the remote server in windows cmd.
Can anyone tell me what's my problem? Do I need to install cygwin to make it work? Thanks a lot.
To get tramp with plink to work, I had to add my PuTTY path to my system search path.
On Windows 10:
control panel >> System & Security >> System >> advanced system settings >> enviroment variables
To PATH I appended the PuTTY path: C:\Program Files (x86)\PuTTY
I'm guessing the key is that from PowerShell or the command prompt, you need to be able to run plink without specifying the path.
I was able to resolve this and I did not have to install cygwin.
Try adding the path where putty was installed to your exec-path variable in emacs. Execute the following elisp code in emacs or put it in your .emacs file. Make sure the slashes are forward, not backslashes, as Emacs and Windows use different conventions.
(add-to-list 'exec-path "C:/Program Files (x86)/PuTTy")
check what exec-path is set to by typing C-h v exec-path
On my main pc (Win 7 64bit) basic windows commands like ping and ipconfig suddenly need admin rights.
If I start a normal command-line window, these commands are not found anymore ("X is not recognized as an internal or external command, operable program or batch file.")
If I start the command-line window with "Run as Administrator" everything works as expected.
On my second PC (Win 7 32 bit) I do not need admin rights.
And I strongly believe that I did not need admin rights on my main pc a couple of weeks ago. Something must have changed, thus I think there must be some (registry) switch or something.
any ideas? thanks a lot
[edit]
I am still the admin user - just starting cmd normally, not with "run as admin"
[edit2]
It indeed was the PATH, variable. Problem was, that Path was saved as the wrong type of string in the registry
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment\Path
has to be a REG_EXPAND_SZ as explained in this thread. Path being of the wrong type of string made it unable to expand %SystemRoot%. Make sure that both your system PATH as well as your user PATH environment variables are of type REG_EXPAND_SZ.
In an effort to narrow down the issue try the following:
open command prompt
make sure you are on the C:\ directory
type this: windows\system32\ipconfig /all
That will point to the default location for the command... You can also follow the path out to see if the ipconfig.exe is there in the first place. If that doesn't work or the file is not there, it could be corrupt or you could possibly have a virus designed to disable these commands.
Srart normal cmd prompt and look at output of the following commands
set path
dir %windir%\system32\ping.exe
dir %windir%\syswow64\ping.exe
dir %windir%\sysnative\ping.exe
Thought, they will show you a problem. May be ping is not found by %path% or somehow...
