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 %*

I wrote a perl script that prints a path to a very specific file. I want to define a personal environment variables (by using setenv in .aliases file) that gives the output of this script.
For example, let's say that the file "myscript.pl" prints the path "/home/files/reports/file". Let's call the variable (that I want to define in .aliases file) 'myoutput'. I want that when I type "most $myoutput" in Unix, this file will be opened by most, and when I type "echo $myoutput", Unix will print the path.
How can I define a personal variable which value is determined by a script?
If you use bash, you can put the following to your .bashrc:
export myoutput=$(perl /path/to/myscript.pl)
For tcsh, use .cshrc instead, and modify the line to
setenv myoutput `perl /path/to/myscript.pl`
You need to start a new session to make the variable exist.
myoutput=$(perl myscript.pl)
When your script prints more, select the correct line:
myoutput=$(perl myscript.pl | grep /home)
I have the following code in my bat file which saved as MyLM.bat:
#echo off
matlab -automation -r "addpath('C:\Users\mojtaba\BrainModel');AddPathes;MyLM('MT5Test_LM')" > matlab_output.log
exit
In which i simply add the main path and then necessary paths and then i run my function (Which is MyLM). I am running the following code from my matlab command prompt :
!start "MATLAB test" /Min /B MyLM.bat
and it works fine and i am happy! So i can run different instances of matlab separately using different bat files. What will makes me happier is that i can pass my argument (which is 'MT5Test_LM') from matlab command prompt. So i dont need to save different bat files. What i actually need is to have some code like this :
!start "MATLAB test" /Min /B MyLM.bat 'MT5Test_LM'
then i need some piece of codes in my bat file to read this argument and concatenate some strings.
Is there any suggestion?
Have you tried using the input argument of the batch file (%1)?
See, e.g., this manual on batch file input argument.
You might want your bathc file to look like
matlab -r "myLM( %1 )"
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 am doing a batch scripting assignment where I have to call one script from inside another. I need the script to run the second script no matter where my lecturer saves these scripts. How would I do this. Is there some way to find the path of script inside the script and use that to execute the file. Any help would be great. I think I need to use %'s but i'm not sure.
The name of the script is Hello World.bat.
How would I copy Hello World.bat to the C:\ if I don't know which directory the lecturer has placed it in. what command/s would I use so that the copy would work regardless of the scripts location.
I don't see the "DOS" tag, but I'll assume that it is for now. If you want the entire path, you can get it by doing this:
echo %cd%
If you want just the last folder, this works (inside a .bat file):
for %%* in (.) do #echo %%~n*
Note that from the command line, the above command will work with single %'s:
for %* in (.) do #echo %~n*
If the script you are executing is calling other scripts in the SAME folder location, you can prefix the path statement with "%~dp0" or "%~dps0" but do not put a backslash between that and the name of the script you are calling. In other words, if script1.bat is calling script2.bat in the same folder, the statement in script1.bat would refer to "%~dp0script2.bat"
sorry about batch files, am not familiar, but in nix shell, there is the locate command which can return the path of the file , if you know the filename exactly and the name is unique.
like
name=$(locate filname)
Im searching a tool which allows me to specify some folders as "bookmarks" and than access them on the commandline (on Windows XP) via a keyword. Something like:
C:\> go home
D:\profiles\user\home\> go svn-project1
D:\projects\project1\svn\branch\src\>
I'm currently using a bunch of batch files, but editing them by hand is a daunting task. On Linux there is cdargs or shell bookmarks but I haven't found something on windows.
Thanks for the Powershell suggestion, but I'm not allowed to install it on my box at work, so it should be a "classic" cmd.exe solution.
What you are looking for is called DOSKEY
You can use the doskey command to create macros in the command interpreter. For example:
doskey mcd=mkdir "$*"$Tpushd "$*"
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:

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.
