A helpful FAQ from Stata describes that arguments can be passed to do files. My do file looks like this:
* program.do : Program to fetch information from main dataset
args inname outname
save `outname', emptyok // file to hold results
insheet using `inname', comma clear names case
// a bunch of processing
save `outname', replace
According to the FAQ, this script can be run using do filename.csv result.dta. When I run this command from within Stata, everything works fine. The program is long, however, so I want to run it in batch mode. Stata has another FAQ about batch mode.
Combining the information from these webpages, I type the following at my Unix prompt:
$ nohup stata -b do program.do filename.csv result.dta &
Stata starts up, but it terminates with the following error:
. save `outname', emptyok // file to hold results
invalid file specification
r(198);
A little experimentation tells me that Stata is never receiving the two arguments when I run the program in batch mode. What is the solution to this problem? (i.e. how do you pass arguments to a do file when running it in batch mode?)
The thread below may be helpful:

In Windows, if my program Test.do is:
args a b
display "`a'"
display "`b'"
I can run it in batch mode in Windows by simply typing:
"c:\Stata13\stata.exe" /e do "c:\Scripts\Test.do" Test Script
And it will display (within Stata):
Test
Script
So I wonder whether the nohup is what's preventing your program from working.

It is possible to supply batch commands directly with the -b flag, but if the commands become very long, this is no longer an option. Is there a way to give the path to an .scm script that was written to a file, without having to move the file into the scripts directory?
No as far as I know. What you give in the -b flag is a Scheme statement, which implies your function has already been loaded by the script executor process. You can of course add more directories that are searched for scripts using Edit>Preferences>Folders>Scripts.
If you write your script in Python the problem is a bit different since you can alter the Python path before loading the script code but the command line remains a bit long.
I am currently trying to create a script that executes a program 100 times, with different parameters, typically pretty simple, but it's adding strange characters into the output filename that is passed into the command call for the program, the script i have written goes as follows
#!/bin/bash
for i in {1..100}
do ./generaterandomizedlist 10 input/input_10_$i.txt
done
I've taken a small screenshot of the output file name here

(extra characters are not recognized by chrome so simply pasting the name doesn't work)
It doesn't do this when i manually call the command issued in the script, any ideas?
Your script has some stray CRs in it. Use dos2unix or tr to fix it.
Hi I am at a loss on how to run multiple commands using popen,
I am trying to automate a series of steps that are normally run on the Windows command line. The basic steps are usually run from the Windows cmd line are
Run a windows command script (.cmd) file to setup environment variables i.e C:\Program Files (x86)\appsettings\setupvariables.cmd
type in the command to connect to the database
type in the command to get data from the database
Stop connection to the database
All these commands must run in the same command line window one after another, not separate processes or separate command line windows. Instead of opening a cmd window and typing in the command I want to use python's subprocess.popen command
So far I have:
args=[]
args.append(r'C:\Program Files (x86)\appsettings\setmyvars.cmd')
args.append(r'start db on db_path="my_url"')
args.append(r'get_data_from_db>c:\temp\output.txt')
args.append(r'stop db on db_path="my_url"')
p=Popen(args,stdout=PIPE,sterr=PIPE,shell=True)
stdout,stderr=p.communicate()
if stderr:
print "you have an error", stderr
else:
print "well done you have data", stdout
This isn't quite working I can see that the first line is run i.e the setmyvars.cmd is executed, but nothing else, none of the other arguments get called, if they did I would see the results in the ouput.txt file.
How do I run a series of commands one after the other using popen. Why is it only the first command seems to be executed and none of the others
I am using python2.7 on Windows
Regards.
You have a couple of issues going on. You still have to tell popen() which program to run. Just using shell=True does not obviate the need to provide cmd.exe as the program to run. If you really want to run all of these commands with one invocation of cmd.exe, then you will need to string them together with &&.
from subprocess import *
args=[]
args.append(r'C:\Windows\System32\cmd.exe')
args.append(r'/C')
args.append(r'(echo 1 && echo 2 && echo 4)')
p = Popen(args,stdout=PIPE,stderr=PIPE,shell=True)
stdout,stderr=p.communicate()
if stderr:
print "you have an error", stderr
else:
print "well done you have data", stdout
It would probably be better to use the %ComSpec% environment variable than it would be to hardcode the location of cmd.exe. The path you have is -usually- correct. :-)
I have a batch file (build.bat) which calls a bash script (makelibs.sh). The bash script contains several commands which build 20 libraries from source.
If I run makelibs.sh from MSYS, I get continuous output. If I call it from the batch file, then I see the full output only at the end of every single command.
This makes it difficult to assess the current status of the process.
Is it possible to redirect the output of makelibs.sh in order to get a continuous feedback on the execution?
I have a batch file (build.bat) which calls a bash script (makelibs.sh)
I strongly advise against doing this. You are calling a script with a script, when you could simply open up Bash and put
makelibs.sh
However if you insist on doing this then perhaps start would work
start bash.exe makelibs.sh

Is there a way, to send commands to another command-line program?
'Cause i have a special command-line program, but I can't send commands to it using syntax like program.exe something_to_do
the program executes something like this: ("here syntax" is where i want to input text to and also enter to start)
TheWhateverCommandLineProgram
Version 1.1
Give an option: "here syntax"
the program in code looks something like this:
echo TheWhateverCommandLineProgram
echo Version 1.1
Set opt=
set /p opt=Give an option:
if %opt%==command1 goto com1
if %opt%==command2 goto com2
...
Well, i guess so cause it wasnt me who made it (btw: off course its not called TheWhateverCommandLineProgram)
If you just want to give keyboard input to a commandline program you can just use echo and pipe it:
echo some text | program.exe
If you need more lines, then write them to a file and use input redirection:
echo one line > file
echo second line >> file
program.exe < file
I'm not 100% sure I understand what you're looking for. Here's two options:
You have two windows, each running a batch program. Let's say they are called myscript1.bat and myscript2.bat. You want to send a set of commands from myscript1.bat to be executed by myscript2.bat
You have a single batch script named myscript.bat, which executes a single program named program.exe. You want program.exe to execute some commands, or do some something.
Are either of these what you're looking for? Here's some idea:
Make myscript1.bat create a third file, mycommands.bat. Once myscript2.bat sees the file mycommands.bat exists, it will execute it and delete it. (Wow. Lame.)
Use Windows Scripting Host command (it's built in to Windows since Win2K) or Powershell (usually on most computers nowadays, if they have been updated). Either of these can send keystrokes to another program. Using those keystrokes, you can control the other program.
In what form does the other program take input? From the command prompt?
If the latter then I recommend Autohotkey: http://www.autohotkey.com/
You can use Autohotkey as a bridge and it will send the command as keypresses to the window of the other batch file.
You can ask for help in their forum. They are quite helpful.
