How can I open any type of file in a .bat by providing only a name of the file, no extension?
I want to let windows decide the application to use.
example:
%SystemRoot%\explorer.exe E:\SomeFolder\
%SystemRoot%\explorer.exe E:\SomeFolder\file1
Use START command:
start "Any title" E:\SomeFolder\
start "Any title" E:\SomeFolder\file1
Taken from Start help:
If Command Extensions are enabled, external command invocation
through the command line or the START command changes as follows:
.
non-executable files may be invoked through their file association just
by typing the name of the file as a command. (e.g. WORD.DOC would
launch the application associated with the .DOC file extension).
See the ASSOC and FTYPE commands for how to create these
associations from within a command script.
.
When searching for an executable, if there is no match on any extension,
then looks to see if the name matches a directory name. If it does, the
START command launches the Explorer on that path. If done from the
command line, it is the equivalent to doing a CD /D to that path.
Note that previous description imply that the pure filename must also execute the right application, with no START command. To pick up the first file with a given name:
for %%f in (name.*) do set "filename=%%f" & goto continue
:continue
... and to execute it:
%filename%
PS - Note that you want "to let windows decide the application to use", but in your example you explicitly select %SystemRoot%\explorer.exe as the application to use. So?

I'm on c drive in command line
when I want to change the directory to D drive using :
cd /C D:\Riot Games
I get an error also with cmder
Assuming you're using Windows, and you're using the standard cmd.exe for your command line, you should be quoting your path arguments for safety even though the docs will tell you it isn't strictly necessary since the command doesn't treat spaces as delimiters. The correct syntax is simply:
cd "D:\Riot Games"
There is also no /C argument to the cd command. You may have meant to use:
cd /D "D:\Riot Games"
to change the current drive in addition to changing the current directory, but whether that's actually necessary isn't clear from your example.
On Windows CMD, you first need to switch to your other drive by just typing D:, then you can change directory by using the cd "Riot Games"
imagine I have a files with certain extensions (for example '.abc').
The default program I set for files with this special extension is a batch script with powershell commands in it, so when I doubleclick the file, it runs the script. It works.
Now my question is, can I somehow get the file path of the .'abc' file I opened? Is there a command for this?
Thank you.
Inside of your batch file it should be possible to access the ".abc" file via parameter %1.
Per default Windows sends the filename of the file you doubleclick to the receiving program (or batch script) as parameter one.
Try this inside of your batch file (near the top) and pick what suits your needs:
echo param1: %1
echo param1 unquoted: %~1
echo drive: %~d1
echo drive and path: %~dp1
echo filename and extension only: %~nx1
set myparam=%~1
echo myParam: %myparam%
See the help documentation of for for the "%~..." syntax by executing for /? in a cmd.exe command window. (Or read here: What does %~dp0 mean, and how does it work?)
I have two files in the same folder that I'd like to run. One is a .txt file, and the other is the program shortcut to an .exe. I'd like to make a batch file in the same location to open the text file and the shortcut then close the batch file (but the text file and program remain open).
I tried this with no luck:
open "myfile.txt"
open "myshortcut.lnk"
Also didn't work:
start "myfile.txt"
start "myshortcut.lnk"
I was able to figure out the solution:
start notepad "myfile.txt"
"myshortcut.lnk"
exit
This would have worked too. The first quoted pair are interpreted as a window title name in the start command.
start "" "myfile.txt"
start "" "myshortcut.lnk"
Don't put quotes around the name of the file that you are trying to open; start "myfile.txt" opens a new command prompt with the title myfile.txt, while start myfile.txt opens myfile.txt in Notepad. There's no easy solution in the case where you want to start a console application with a space in its file name, but for other applications, start "" "my file.txt" works.
The command-line syntax for opening a text file is:
type filename.txt
File types supported by this command include (but are not limited to): .doc, .txt, .html, .log
If the contents is too long, you can add "|more" after "type filename.txt", and it will pause after each screen; to end the command before the end of the file, you can hold Ctrl + C.
I use
#echo off
Start notepad "filename.txt"
exit
to open the file.
Another example is
#echo off
start chrome "filename.html"
pause
You can also do:
start notepad "C:\Users\kemp\INSTALL\Text1.txt"
The C:\Users\kemp\Install\ is your PATH. The Text1.txt is the FILE.
"location of notepad file" > notepad Filename
C:\Users\Desktop\Anaconda> notepad myfile
works for me! :)
In some cases, when opening a LNK file it is expecting the end of the application run.
In such cases it is better to use the following syntax (so you do not have to wait the end of the application):
START /B /I "MyTitleApp" "myshortcut.lnk"
To open a TXT file can be in the way already indicated (because notepad.exxe not interrupt the execution of the start command)
START notepad "myfile.txt"
The command start [filename] opened the file in my default text editor.
This command also worked for opening a non-.txt file.
If you are trying to open an application such as Chrome or Microsoft Word use this:
#echo off
start "__App_Name__" "__App_Path__.exe"
And repeat this for all of the applications you want to open.
P.S.: This will open the applications you select at once so don't insert too many.
Try using:
#ECHO off
ECHO Hello World!
START /MAX D:\SA\pro\hello.txt
Its very simple,
1)Just go on directory where the file us stored
2)then enter command i.e. type filename.file_extention
e.g type MyFile.tx
To open a file with default software just need to type the path of the file or, if you are at the file location, the file name.
C:\Users\MyName>C:\User\MyName\Desktop\hello.txt
or
C:\Users\MyName\Desktop>hello.txt
If you want specific program like notepad you can specify it first.
C:\Users\MyName>notepad C:\User\MyName\Desktop\hello.txt
or
C:\Users\MyName\Desktop>notepad hello.txt
Note that notepad is usually default text editor for .txt, in this case would make more sense to type notebook only to open a .cs/.cpp/.py file if your default for that files is any IDE and you just want to see the file on notebook
Regarding the batch file it will work the same way but to open them at the same time and let the command line go away you should use:
start "title" {filename}
So the command can open the file and return to next line immediately.
start "" C:\Users\MyName\MyFolder\foo.exe
start "" C:\Users\MyName\MyFolder\notes.txt
or
start "" foo.exe
start "" notes.txt
The last one only works if the batch file is on the same location of the files.
If you plan on using the console to open the batch file and you want the console to close at the end you should indeed write exit on last line.
When in doubt, it always helps to read the docs:
>help start
Starts a separate window to run a specified program or command.
START ["title"] [/D path] [/I] [/MIN] [/MAX] [/SEPARATE | /SHARED]

node as a decimal integer.
AFFINITY Specifies the processor affinity mask as a hexadecimal number.
Picture for the visual learners:
I am trying to find a way to register the files with extension .pl as executables.
I spent some time on the web looking for a solution, but I couldn't find anything.
What I can do:
I made a script, let's call it myscript.pl
I can run it like this :
perl myscript.pl [my_script_parameters]
Now since the file is associated with perl, I can also run it as:
myscript.pl [my_script_parameters]
Now, I know that there is somewhere a list of extensions that are considered as executables (.exe, .bat, etc…). I would like to add .pl to this list so that I can run my script like this:
myscript [my_script_parameters]
Does anyone know how to do this?
Yes, there is built-in support for this. If you check the help for command FTYPE you will see a perl example.
C:>help ftype
Displays or modifies file types used
in file extension associations
FTYPE [fileType[=[openCommandString]]]
fileType Specifies the file type to
examine or change openCommandString
Specifies the open command to use when
launching files
of this type.
Type FTYPE without parameters to
display the current file types that
have open command strings defined.
FTYPE is invoked with just a file
type, it displays the current open
command string for that file type.
Specify nothing for the open command
string and the FTYPE command will
delete the open command string for the
file type. Within an open command
string %0 or %1 are substituted with
the file name being launched through
the assocation. %* gets all the
parameters and %2 gets the 1st
parameter, %3 the second, etc. %~n
gets all the remaining parameters
starting with the nth parameter, where
n may be between 2 and 9, inclusive.
For example:
ASSOC .pl=PerlScript
FTYPE PerlScript=perl.exe %1 %*
would allow you to invoke a Perl
script as follows:
script.pl 1 2 3
If you want to eliminate the need to
type the extensions, then do the
following:
set PATHEXT=.pl;%PATHEXT%
and the script could be invoked as
follows:
script 1 2 3
You can simply add ";.PL" to the PATHEXT environment variable. Right-click "My computer" > Properties > Advanced > Environment variables > System variables.
Your best approach would be to write a batch file called myscript.bat, place it in your path, and have it run your script.. e.g.
#echo off
c:\perl\bin\perl.exe c:\scripts\myscript.pl %*
Im searching a tool which allows me to specify some folders as "bookmarks" and than access them on the commandline (on Windows XP) via a keyword. Something like:
C:\> go home
D:\profiles\user\home\> go svn-project1
D:\projects\project1\svn\branch\src\>
I'm currently using a bunch of batch files, but editing them by hand is a daunting task. On Linux there is cdargs or shell bookmarks but I haven't found something on windows.
Thanks for the Powershell suggestion, but I'm not allowed to install it on my box at work, so it should be a "classic" cmd.exe solution.
What you are looking for is called DOSKEY
You can use the doskey command to create macros in the command interpreter. For example:
doskey mcd=mkdir "$*"$Tpushd "$*"
creates a new command "mcd" that creates a new directory and then changes to that directory (I prefer "pushd" to "cd" in this case because it lets me use "popd" later to go back to where I was before)
The $* will be replaced with the remainder of the command line after the macro, and the $T is used to delimit the two different commands that I want to evaluate. If I typed:
mcd foo/bar
at the command line, it would be equivalent to:
mkdir "foo/bar"&pushd "foo/bar"
The next step is to create a file that contains a set of macros which you can then import by using the /macrofile switch. I have a file (c:\tools\doskey.macros) which defines the commands that I regularly use. Each macro should be specified on a line with the same syntax as above.
But you don't want to have to manually import your macros every time you launch a new command interpreter, to make it happen automatically, just open up the registry key
HKEY_LOCAL_MACHINE\Software\Microsoft\Command Processor\AutoRun and set the value to be doskey /macrofile "c:\tools\doskey.macro". Doing this will make sure that your macros are automatically predefined every time you start a new interpreter.
Extra thoughts:
- If you want to do other things in AutoRun (like set environment parameters), you can delimit the commands with the ampersand. Mine looks like: set root=c:\SomeDir&doskey /macrofile "c:\tools\doskey.macros"
- If you prefer that your AutoRun settings be set per-user, you can use the HKCU node instead of HKLM.
- You can also use doskey to control things like the size of the command history.
- I like to end all of my navigation macros with \$* so that I can chain things together
- Be careful to add quotes as appropriate in your macros if you want to be able to handle paths with spaces in them.
I was looking for this exact functionality, for simple cases. Couldn't find a solution, so I made one myself:
#ECHO OFF

IF [%2]==[] (

ECHO warp /? Display this help
ECHO warp [bookmark] Navigate to existing bookmark

ECHO.
:end
You can list, create and delete bookmarks. The bookmarks are stored in text files in a folder in your user directory.
Usage (copied from current version):
A folder bookmarker for use in the terminal.
c:\Temp>warp /create temp # Create a new bookmark
Created bookmark "temp"
c:\Temp>cd c:\Users\Public # Go somewhere else
c:\Users\Public>warp temp # Go to the stored bookmark
c:\Temp>
Every warp uses a pushd command, so you can trace back your steps using popd.
c:\Users\Public>warp temp
c:\Temp>popd
c:\Users\Public>
Open a folder of a bookmark in explorer using warp /window <bookmark>.
List all available options using warp /?.
With just a Batch file, try this... (save as filename "go.bat")
#echo off
set BookMarkFolder=c:\data\cline\bookmarks\
if exist %BookMarkFolder%%1.lnk start %BookMarkFolder%%1.lnk
if exist %BookMarkFolder%%1.bat start %BookMarkFolder%%1.bat
if exist %BookMarkFolder%%1.vbs start %BookMarkFolder%%1.vbs
if exist %BookMarkFolder%%1.URL start %BookMarkFolder%%1.URL
Any shortcuts, batch files, VBS Scripts or Internet shortcuts you put in your bookmark folder (in this case "c:\data\cline\bookmarks\" can then be opened / accessed by typing "go bookmarkname"
e.g. I have a bookmark called "stack.url". Typing go stack takes me straight to this page.
You may also want to investigate Launchy
With PowerShell you could add the folders as variables in your profile.ps1 file, like:
$vids="C:\Users\mabster\Videos"
Then, like Unix, you can just refer to the variables in your commands:
cd $vids
Having a list of variable assignments in the one ps1 file is probably easier than maintaining separate batch files.
Another alternative approach you may want to consider could be to have a folder that contains symlinks to each of your projects or frequently-used directories. So you can do something like
cd \go\svn-project-1
cd \go\my-douments
Symlinks can be made on a NTFS disk using the Junction tool
Without Powershell you can do it like this:
C:\>set DOOMED=c:\windows
C:\>cd %DOOMED%
C:\WINDOWS>

Are Environment variables defined via "set" not meant for the current session only? Can I persist them?
They are set for the current process, and by default inherited by any process that it creates. They are not persisted to the registry. Their scope can be limited in cmd scripts with "setlocal" (and "endlocal").
Environment variables?
set home=D:\profiles\user\home
set svn-project1=D:\projects\project1\svn\branch\src
cd %home%
On Unix I use this along with popd/pushd/cd - all the time.
