Windows Command prompt shell for sqlite3 - sqlite

The documentation states that there is a command-line shell for sqlite3:
To start the sqlite3 program, just type "sqlite3" followed by the name the file that holds the SQLite database."
When I try this, in the Windows Command Prompt I get the error message:
'sqlite3' is not recognized as an internal or external command,
operable program or batch file.
Windows explorer reveals several 'Sqlite3" folders in various places:
backends(C:/Python26/Lib/site-packages/django/db)
Lib(C:/Python26)
backends(C:/Django-1.1.1/Django-1.1.1/build/lib/django/db
backends(C:/Django-1.1.1/Django-1.1.1/django/db)
How do I access the shell, can anyone help?

Download sqlite3 binary for windows here. Unzip it and put it somewhere in your path.

That's the error message you get if you try to run any executable that's not in your current directory or in the path.
To correct the problem, find the SQLite executable (SQLITE3.EXE), and run it from the directory in which it resides, or add SQLITE3.EXE to your PATH environment variable.

You have to properly set your PATH environment variable to include one of the locations where sqlite3.exe resides. Usually SQLite seems to set that environment variable upon install but the list of paths where you found it indicates that it just came as a library for various other applications. Therefore it's not too surprising that the path isn't set.

I have sqlite3 on my machine, and as others have mentioned it must be located within a folder specified by your PATH environment variable. Since I use it a lot, I threw it in windows\system32, which is where I place a lot of utilities like pstools.

Error that says Rscript is not recognized as an internal or external command, operable program or batch file [duplicate]

shell_exec("Rscript C:\R\R-3.2.2\bin\code.R ");
This is the call to script.On calling the above script, the error occurs.
I am trying to call my R script from the above path but no output is being shown. While checking the error logs of PHP, it says 'Rscript' is not recognized as an internal or external command, operable program or batch file.' The script is working fine on the Rstudio but not running on the command line.
Add the Rscript path to your environment variables in Windows:
Go to Control Panel\System and Security\System and click Advanced System Settings, then environment variables, click on path in the lower box, edit, add "C:\R\R-3.2.2\bin"
Restart everything. Should be good to go. Then you should be able to do
exec('Rscript PATH/TO/my_code.R')
instead of typing the full path to Rscript. Won't need the path to your my_code.R script if your php file is in the same directory.
You need to set the proper path where your RScript.exe program is located.
exec ("\"C:\\R\\R-3.2.2\\bin\\Rscript.exe\"
C:\\My_work\\R_scripts\\my_code.R my_args";
#my_args only needed if you script take `args`as input to run
other way is you declare header in your r script (my_code.r)
#!/usr/bin/Rscript
and call it from command line
./my_code.r
If you are running it in Git Bash terminal, you could follow a revised version of the idea suggested by #user5249203: in the first line of your file my_code.R, type the following
#!/c/R/R-3.2.2/bin/Rscript.exe
I assumed that your path to Rscript.exe is the one listed above C:\R\R-3.2.2\bin. For anyone having a different path to Rscript.exe in Windows, just modify the path-to-Rscript accordingly. After this modification of your R code, you could run it in the Git Bash terminal using path-to-the-code/mycode.R. I have tested it on my pc.
I faced the same problem while using r the first time in VS Code, just after installing the language package (CRAN).
I restart the application and everything worked perfectly. I think restarting would work for you as well.

db2 command not found in unix

I am trying to execute a simple db2 command in Linux command prompt. but Linux command prompt is not recognizing the command it is giving - bash db2 command not found. but db2 is installed in the Linux machine.
command I am trying to execute from Linux command line processor is db2 "create database smaple"
Error I am getting is below "If db2 in not a typo you can run the following command to lookup the package that contains the binary" command-not-found db2 -bash: db2: command not found"
Is this because of environment variable problem ?? or there is only one instance of db2 ie db2inst1 is running in the machine.my user name in appsusr and db2 instance name is db2inst1 are different is this causing problem?? and I am not having super user access.Is this is causing any problem?? do I need super user access is required ??
Just type, echo $PATH in your command prompt , where you can see all the exported paths in your system.
If the db2 path is not found in your environment variable list, then do the following.
export PATH=$PATH:/opt/IBM/db2/V10.1/bin
and then press enter.
I hope this will resolve your issue.
On Linux and UNIX DB2 platforms, the proper way to set your environment variables to run DB2 commands is to source the sqllib/db2profile script belonging to the local DB2 instance owner. That will set not only your PATH but also other important variables that DB2 requires.
In your case, the instance is owned by the db2inst1 user, so your login startup file or batch script should run this command:
. ~db2inst1/sqllib/db2profile
The leading dot is necessary to set the variables in your current shell process, not the sub-process that quickly vanishes after db2profile finishes.
It's more than likely that, if DB2 is installed, it's simply not in your path.
Your path should contain something like:
/opt/IBM/db2/V10.1/bin
which is where the executables live (depending on which version you're running).
Changing your path will probably entail changes to one of the startup files, such as .bashrc or .bash_profile.

iexpress not executing installer

I have an install.bat file and a resource folder. so long as these two files are in the same directory, if you run install.bat, it will install a my lwjgl game. so what im trying to do is make a self extracting file that when completed runs the launch.bat file. I have tried using iexpress, and got it working for the most part. i have added in all my files and such so it will extract to some directory and then i can run the install.bat file to get my program to work. thing is though, i want the exe i created with iexpress to launch install.bat when its finished. so, i tried using the option in iexpress that says it will execute a command when finished the "installation" (using quotes because its not the actual installation, just extracting the files to some directory specified by the user). when i get to the step where it says what i would like to execute during and after the "installation". during the installation i left blank. after the installation i chose the install.bat file. when i try to click next though, it tells me i must choose something for the command during the extraction. I don't have anything specific to do during the installation so i just said "echo." (without quotes). after i was done i tried running the installer. before it even prompted me for a folder to extract to, it told me that echo. could not be executed. so i went back into my installation (via a .sed file) and changed the "echo." to "pause". that didn't work either. i then read on another website that in order to run a file the way i would like to, i put the file name in both the during and after installation boxes. i tried doing that and it didn't work either. can anyone please help me?
If I understood your question correctly you will need to specify what the iexpress must do at the post install command option provided so that cmd.exe is used instead of command.com, eg:
cmd.exe /c filethatyouwanttorun.bat
Refer to the question: Create Batch file for iexpress.
You can use the SED file and then modify the self extraction directive. This will run the batch file that you wanted to run and then install the application. (If you have chosen the option to extract and run an installation in iexpress, a temp folder will be used for the extraction I suppose.)
I'm not sure I understand your question exactly but perhaps a few points would help:
If you want a "do nothing" command, you can use something like:
cmd /c echo.
There is no "command during the extraction". There's only an install program and a post install command. Both of these execute after extraction. If you only need to execute one batch file, put it in the install program line and leave the post install command blank.
You can't ask the user for an extraction path and execute a file. You can only do one or the other. (The install program could prompt the user and copy the files there, though.)

How to run Unix command from Oracle Forms

OS: UNIX Solaries, Oracle Application Server 10g
To run shell script from Oracle Forms, I used the following host('/bin/bash /u01/compile.sh') and it works well
Now, I need to run unix command something like
host('mv form1.fmx FORM1.FMX') but it's not working
I tried to append the command mv form1.fmx FORM1.FMX' to the compile.sh shell script but also it's not working although the rest lines of the shell script is running well
The solution is to just add the full path of the mv command and it worked well, as follow
/bin/mv /u01/oracle/runtime/test/form1.fmx /u01/oracle/runtime/test/FORM1.FMX
In case anyone else encounters the same problem, the cause is that Forms process creates a subprocess to execute host() command, and that subprocess inherits environment variables of the parent process, which are derived from default.env (or other env file as defined in server config). There is a PATH variable defined in that file, but it doesn't contain usual /bin or /usr/bin, so the commands will not execute unless full path is specified.
The solution is to set the correct PATH variable either in the executed script (via export PATH=$PATH:...) or in default.env. I set it in the script, since, knowing Oracle, there's no guarantee that modifying default.env won't break something.

Run SQLite3 in Windows7 - Not Working (unless I Run as Admin)

I downloaded sqlite3, added sqlite3.dll, sqlite3.def and sqlite3.exe to Windows/System32. System32 is in the Windows Path. When I run SQLite3 test.db as per the Quick Start documentation from SQLite, SQLite3 is not recognized.
I also tried registering the dll but that did not work. I looked at numerous posts here and elsewhere but I cannot figure it out.
If I run sqlite3 at the cmd prompt, in System32, it is recognized. But obviously, unless I am missing something I do not want to create databases in the System32 folder. (Update)When I run a command prompt as admin, SQLite3 is recognized. Is that normal?
I guess I am viewing this as the same as Java, in the sense that once Java was added to the path I can run the Java comd from anywhere.
Conversely running in linux has been a smooth event.
Thank you,
diek
Aha! I had the same problem today. sqlite3.exe wouldn't be recognized if it was in C:\Windows\System32 (though interestingly it would work in C:\Windows) and that location was in the path.
I solved this by "unblocking" the file as it was a downloaded file that Windows doesn't trust: Properties > General > "Unblock"
This would possibly explain why running as admin worked.
It is also possibly related to this issue of 32-bit vs. 64-bit windows, though I think it is the earlier blocking problem.
