So I installed VLC into the directory D:\misc\vlc and when I type "vlc" into command prompt, it starts the VLC media player. However, I want to run this "vlc" command in the directory D:\slam\ . However, every time I do that, it says that "'vlc' is not recognized as an internal or external command,
operable program or batch file.".
Is there a way to run the 'vlc' command in any directory?
Any help is appreciated.
You can add the vlc program to the PATH in Windows using the "Edit Environment Variables" dialog. Assuming Windows 10 (though this dialog is present in older versions too), here is how to add a program to the PATH:
Open the Start Search, type in “env”, and choose “Edit the system environment variables”
Click the “Environment Variables…” button.
Under the “System Variables” section (the lower half), find the row with “Path” in the first column, and click edit.
The “Edit environment variable” UI will appear. Here, you can click “New” and type in the new path you want to add. From this screen you can also edit or reorder them.
Dismiss all of the dialogs by choosing “OK”.
Your changes are saved! You will probably need to restart apps for them to pick up the change. Restarting the machine would ensure all apps are run with the PATH change.
In step 4 above, the new path that you will type is the directory containing the vlc program, e.g. "D:\misc". Note that adding this directory will also make any other programs inside of the "misc" directory accessible as well.

I have Ruby installed, but I still need to add it to the PATH variable. I found something online for how to manually add it using the command line:
set PATH=C:\Ruby200-x64\bin;%PATH%
But before I try it, I want to be sure it's not going to overwrite what's currently in the PATH variable. (I have no experience with this stuff so I don't know what to expect).
Thanks in advance for your help!
first, notice that this question is not really about Ruby, rather about how to set a path in windows (it work the same way if you want to add an executable different from Ruby)
second, you are not overwriting the PATH environment variable because you add the existing content of the same to the new one you are setting in:
set PATH=C:\Ruby200-x64\bin;%PATH%
the %PATH% is the current content of the PATH variable.
Consider using
set PATH=%PATH%;C:\Ruby200-x64\bin
instead, this will make your OS search the original path before searching the ruby bin folder. Maybe it makes few difference on modern computers, but my old DOS days claim the second solution is better.
third and last point, in Windows you can set environment variables in control panel / system properties
How to get there depends on the version of your OS, but if you search for the ambient variables and system variables you should get there.
From the Desktop, right-click the very bottom left corner of the screen to get the Task Menu.
From the Task Menu, click System.
Click the Advanced System Settings link in the left column.
In the System Properties window, click on the Advanced tab, then click the Environment Variables button near the bottom of that tab.
In the Environment Variables window (pictured below), highlight the Path variable in the "System variables" section and click the Edit button.
Add or modify the path lines with the paths you want the computer to access. For ruby it will be:
;YOUR_RUBY_INSTALLATION_PATH\bin;
The operation with set PATH=C:\Ruby200-x64\bin;%PATH% is probably only temporary until you restart your computer.
I just wanted to let everyone know that when you install rubyinstaller on Windows and follow its steps, there is no option to 'add to path variables' because it automatically adds it.
Rubyinstaller trolled me hard because it said gem not found when I did gem install sass immediately after install.
Your path variable is probably already set if you used rubyinstaller.
The trick is to open CMD or I would imagine, PowerShell, ConEMU, etc, git bash, and type gem.
Press WINKEY and type cmd
Type gem install sass (or whatever else that is in the bin folder for Ruby)
I just went to add the PATH variable, and it was already set, so my problem was the garbage command line tool that opened after installing rubyinstaller.
You can also do these steps to add to the PATH variables:
Press WINKEY
Type view advanced system settings
Open that
Click Environment Variables
Click Path in the list
Click Edit
Check if C:\Ruby24-x64\bin is already there, if so, done
Click New and type in C:\Ruby24-x64\bin
Done
Yes, this is correct. In your example %PATH% will be expanded to the current value of the PATH variable, so this command is effectively adding a new entry to the beginning of the PATH.
Note that calling set PATH will only affect the current shell. If you want to make this change permanent for all shells, the simplest option is to set it as a user variable using the Environment Variables dialog box.
On Windows 8 you can open this dialog by hitting Win+s and searching for 'environment variables'. On earlier versions of Windows you can right-click 'My Computer', choose Properties, then Advanced system settings, then Environment variables. You can create (or update) a PATH variable in the user variables section and add whatever entries you need. These will be appended to the existing system path. If you take this approach you will need to open a new cmd shell after updating the variables.
Fear nothing, What you are doing is prepend C:\Ruby200-x64\bin to the existing %PATH%, this is what the command you posted does.
The path is a list of directories, separated by ;, in which the system will look for the command you execute.
In your case it's:
C:\Ruby200-x64\bin
%PATH%, if you print it on the command line, you'll find it's itself a list of directories separated by ;.
In case you want to make your change permanent, you have to change your PATH sytemwide.
For CLI, as noted elsewhere calling SET on the path variable only acts on the current window and closing it or restarting windows voids the change.
Example the transient Version selected as the answer:
set "PATH=%PATH%;C:\Ruby200-x64\bin"
To correctly set the path permanently in CLI use the path command:
PATH %PATH%;C:\Ruby200-x64\bin
This will persist between CMD windows and after reboots.
I know this is questions has the Windows tag, however it is one of the first DuckDuckGo results for "ruby gems add to path" so I just wanted to add this.
On Linux you can add this line to the end of your .bashrc in order to add it to your path:
export PATH=$PATH:~/.gem/ruby/2.6.0/bin
I am creating a directory synch application in java programming application. Now i want to add share option when user right click with in a specific directory, and want to open an dynamic url on clicking that new option. Can anyone help me to find any good solution. Can anyone provide me Registry Script For this task.
An msdn resource on Extending Shortcut Menus will be good for you.
Anyway, I'd like to introduce my own "minimal" example. This opens a gnuplot's wgnuplot terminal at the right-clicked directory after choosing "Open gnuplot here" shortcut.
You can add keys into HKEY_CLASSES_ROOT\Directory\shell. I added HKEY_CLASSES_ROOT\Directory\shell\gnuplot with string (name: (Default)) Open gnuplot here, provided an icon string with the program's icon path, a LegacyEnable empty string and a command key that windows have to execute when clicking. You can reach the right clicked directory name with %V (You can find out more special variables on this Q&A thread at SU). Here's the code that creates the structure:
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\Directory\shell\gnuplot]
#="Open gnuplot here"
"Icon"="\"C:\\Windows\\icons\\wgnuplot.ico\""
"LegacyEnable"=""
[HKEY_CLASSES_ROOT\Directory\shell\gnuplot\command]
#="\"C:\\Users\\Cron\\Documents\\egyetem\\gnuplot\\bin\\pgnuplot.exe\" -e \"cd '%V'\" -persist"
Where is in the registry the path executed when I run the "notepad" command in windows "Start->run command" interface? I want to change it for notepad++ (it is required so, although could look not really good)
If you are like me you use windows run command all the time. I hate using the mouse to point and click a shortcut on the start menu. WIN-R are probably the two most over used keys on my keyboard. After thinking about if awhile I hunted down how the run command works. It turns out that it makes a call to ShellExecute, which I guess is not too surprising. The next thing I wanted to find out was exactly how the commands are resolved. The following is an ordered list of how they are resolved ([1]):
The current working directory
The Windows directory (no subdirectories are searched)
The Windows\System32 directory
Directories listed in the PATH environment variable
The App Paths registry key
Naturally the next thing I wanted to do was customize existing commands or add new commands so I do not have to type as much (standard lazy approach). After examining my options which were to put the executable in one of those paths (since it only locates executables and not shortcuts), modify the path environment variable or add a key to App Paths. The App Paths option seems to be the easiest and most flexible to me. Here is a layout of what you need to do to add an App Paths entry ([1]):
HKEY_LOCAL_MACHINE-->
SOFTWARE-->
Microsoft-->
Windows-->
CurrentVersion==>
App Paths-->
file.exe-->
(Default) = The fully-qualified path and file name
Path = A semicolon-separated list of directories
DropTarget = {CLSID}
Disclaimer: Modifying the registry can cause serious problems that may require you to reinstall your operating system. I cannot guarantee that problems resulting from modifications to the registry can be solved. Use the information provided at your own risk.
The minimum needed to add a new entry is to add the key file.exe where file is the string you want to type into the run command and to add the Default entry which is the fully-qualified path to the file you want to execute. Note that even it the file you are going to reference isn't an exe file you still need to put the .exe on the key. Here is a sample registry file that I created to add a shorter keyword for Internet Explorer:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App
Paths\ie.exe] #="C:\Program Files\Internet Explorer\iexplore.exe"
After entering that entry into the registry I can simply type “ie” at
the run command to open internet explorer.
Here is a list of some common commands I use at the run command:
cmd – Command prompt winword – Microsoft Word excel – Microsoft Excel
outlook – Microsoft Outlook iexplore – Internet Explorer firefox –
Mozilla Firefox notepad – Notepad compmgmt.msc – Computer Management
Console control appwiz.cpl – Add/Remove programs dialog mstsc –
Microsoft Terminal Service Client regedit – Registry Editor
…
If there is some program that I find myself using all the time I figure out what the run command is for it and if there is not a short easy one I add one to my App Paths as described above. Does anyone else have some other common run commands they use?
I would work much faster if I could have some kind of command line running inside rubymine, is this possible? When testing I repeatedly have to switch to my terminal window and it gets quite annoying.
I can run rails console and also the sandboxed version side rubymine aswell as my rails server and spork server.
It would be nice to have a command prompt inside rubymine also would speed things up. Infact that would make rubymine 100% perfect for my rails development as it does everything else require.
There is no such feature in IDEA platform based products. You need to run terminal externally. Note that you can create an External Tool to run terminal window in the current file or module directory for convenience.
UPDATE: Terminal (SSH console) was added in PhpStorm/WebStorm 7.0, IDEA 13, RubyMine 6, PyCharm 2.7.3.
I have used CrazyCoder's instructions to do this. Here are the instructions for Windows:
File, Settings
bottom half of menu is titled IDE Settings, look in this list to find External Tools
Click in the only available button (for most), [+]
give your custom thing a name ("terminal"? "command prompt"?)
most of this stuff you just leave blank
click the [...] button next to Program, then simply navigate to Windows/system32/cmd.exe
Lastly, unless you want to have your starting command line (terminal) path as C:\Windows\system32 (CHANGE YOUR PATH), simply click on the [...] next to the "Working Directory" just below, and change your path to Desktop or whatever it is you prefer.
Click OK.
You're done! It's that easy. Now to access this (no restart required), click on Tools, and then under 'XML actions' (for me anyway) you should find your "terminal" or "cmd" or whatever it is you called it. You can test it out with an 'ipconfig' command. You can always go back to the the settings/external-tools place you went to in the first place to edit your settings (like your default path), or to make another custom tool, because this (RubyMine External Tools creator) is obviously a very powerful tool.
If someone is searching this for rubymine in version 7.
Press Alt+f12 for the terminal.

I have Python 2.6 installed on Windows Vista. If I am at C:\Python26> and I type python, Python's command-line interface starts, as desired.
I have added C:\Python26 to my PATH so that I would be able to run Python scripts from any directory, but it hasn't helped. In particular, from any other directory, the command python is not recognized.
I appreciate any guesses as to what change would get this working.
Edit: First, I have re-opened my cmd window (several times) so that is not the issue.
To clarify how I added C:\Python26 to the PATH, I clicked the following:
Computer -> System Properties -> Advanced system settings -> Environment Variables
at the point I select PATH and click Edit. I added C:\Python26 to the Variable Value field, separating this from the previous entries with a semicolon. Then I click OK a few times.
Edit #2 I've now checked my PATH by typing path at the command prompt. C:\Python26 is certainly in the path. I'll reboot anyway, and see if that helps.
This still sounds like a path issue.
If you have just added c:\Python26 to your path, then you need to open a new cmd window before those changes take effect, they won't apply to your existing cmd windows.
If you're unsure how to do this in Windows Vista, here is the instructions.
Select Settings -> Control Panel from the start menu.
Double click the 'System' icon.
Choose 'Advanced System Settings' on the left hand side.
Choose 'Environment Variables'
In the bottom list, select 'Path', and click 'Edit...'
At the end of the path string, add ;C:\Python26, leaving everything else the same, then click OK, then click OK again on the various windows still open.
Now open a new cmd window, and try the 'python' command from any directory - it should work.
This may be obvious to most people, but hopefully anyone with the same problem will find the help they need in this answer.
if you are certain that you have added the directory to the path, you may just need to open up a new command window for it to take the changes to the current path.
Double and triple check that you added the path correctly and didn't make a typo.
Restart your machine.
In the top panel where it says User Variables for YOUR NAME HERE,
select path, click the top edit button.
Append ";C:\Python26" without quotes at the end of the text in the "Variable Value" textbox.
That solved the problem for me.
Other options are to reinstall or to create a .bat file with c:\python26\python.exe and put that in your path
