I have two batch files.
File a:
SET Variablex=0
File b:
SET Variabley=1
SET %Variablex%=%Variabley%
ECHO %Variablex%
The result is 0 and not 1 as expected. I tried various options such as quotes, exclamation etc.
The value of VariableX is lost when batch file a has done executing.
If you call file b from within file a, then it should work.
File b:
SET "Variabley=1"
SET "Variablex=%Variabley%"
ECHO %Variablex%

I want to run experiments using behavior space. However, the number of experiments needed is depending on the length of a list which is dynamic subject to the external data loaded. Hence , I want to do something like below which is not supported:
what is the correct way to do so? thanks
You note that you do this with a .bat or .sha file. If that's the case, here's a .bat solution. However, I'm not sure what your data looks like- in this example I just used the number of entries in a csv file to determine the number of runs needed.
So, I have a data file called 'example_data.csv' that looks like this:
1
100
1000
10000
I have an .nlogo file with an Input widget that defines a global variable called n_runs. I pulled out the xml for an BehaviorSpace experiment and saved it in a file called "experiment_base.xml"- it looks like:
<experiments>
<experiment name="experiment" repetitions="1" sequentialRunOrder="false" runMetricsEveryStep="false">
<setup>setup</setup>
<go>tick</go>
<timeLimit steps="5"/>
<metric>count turtles</metric>
<steppedValueSet variable="n_runs" first="1" step="1" last="1"/>
</experiment>
</experiments>
I have a .bat file that:
counts the number of entries in my 'example_data.csv"
reads in the 'experiment_base.xml' file and replaces the last="1" with the number read above, then writes this as a new experiment called 'mod_experiments.xml'
runs the experiment using the newly generated experiments file
This entire bat file looks like:
#echo off
cls
setlocal EnableDelayedExpansion
set "cmd=findstr /R /N "^^" example_data.csv | find /C ":""
for /f %%a in ('!cmd!') do set number=%%a
powershell -Command "(gc experiment_base.xml) -replace '<steppedValueSet variable=\"n_runs\" first=\"1\" step=\"1\" last=\"1\"/>', '<steppedValueSet variable=\"n_runs\" first=\"1\" step=\"1\" last=\"%number%\"/>' | Set-Content mod_experiments.xml
echo "Running experiment..."
netlogo-headless.bat ^
--model dynamic_behaviorspace.nlogo ^
--setup-file mod_experiments.xml ^
--table table-output.csv
This outputs results for 4 experiments, since I had 4 values in my data file. If I modify the number of entries in the csv and rerun the .bat file, I get results for a corresponding number of runs.
I need to merge 3 input files into 1 output file via datastage, may I know how to achieve this?
Background:
The 3 input files have different fields (layout)
example:
Input file A: HDR123
Input file B: 000123
Input file C: TRL003
Expected output:
HDR123
000123
TRL003
You can use the funnel stage for this but the data types and length need to match (similar to a union in SQL).
You can achieve this in datastage by defining two jobs:
Job-1. parallel job: sequential file -> sequential file
Job-2. sequence job: startloop activity -> job activity -> endloop activity
Define job-1 as follows:
source sequential file
Define job parameter, say #INPUT# and use this value as file name in the file path, say : /tmp/#INPUT#
i.e. input files are /tmp/A, /tmp/B and /tmp/C
target sequential file
Output file, say /tmp/out.txt
File update mode : Append
Define job-2 as follows:
start loop activity : Loop definition -> delimited values : A,B,C (Delimiter comma)
job activity: Job name = above job-1
Parameters : INPUT = StartLoop_Activity_0.$Counter
Now compile both job-1 and job-2
Run sequence job job-2. You will expected result in /tmp/out.txt
Please note that, if you run the sequence job again, you will see the same contents appended again, so you need to make sure you have no file called /tmp/out.txt before running sequence job or it is empty.
I apologize in advance that this question is not specific. But my goal is to take a bunch of image files, which are currently named as: 0.tif, 1.tif, 2.tif, etc... and rename them just as numbers to 000.tif, 001.tif, 002.tif, ... , 010.tif, etc...
The reason I want to do this is because I am trying to load the images into matlab and for batch processing but matlab does not order them correctly. I use the dir command as dir(*.tif) to get all the images and load them into an array of files that I can iterate over and process, but in this array element 1 is 0.tif, element 2 is 1.tif, element 3 is 10.tif, element 4 is 100.tif, and so on.
I want to keep the ordering of the elements as I process them. However, I do not care if I have to change the order of the elements BEFORE processing them (i.e. I can make it work to rename, for example, 2.tif to 10.tif if I had to) but I am looking for a way to convert the file names the way I initially described.
If there is a better way to get matlab to properly order the files when it loads them into the array using dir please let me know because that would be much easier.
Thanks!!
You can do this without having to rename the files, if you want. When you grab the files using dir, you'll have a list of files like so:
files =
'0.tif'
'1.tif'
'10.tif'
...
You can grab just the numeric part using regexp:
nums = regexp(files,'\d+','match');
nums = str2double([nums{:}]);
nums =
0 1 10 11 12 ...
regexp returns its matches as a cell-array, the second line converts it back to actual numbers.
We can now get an actual numeric order by sorting the resulting array:
[~,order] = sort(nums);
and then put the files in the correct order:
files = files(order);
This should (I haven't tested it, I don't have a folder full of numerically labelled files handy) produce a list of files like so:
files=
'0.tif'
'1.tif'
'2.tif'
'3.tif'
...
this is partially dependent on the version of matlab you have. If you have a version with findstr this should work well
num_files_to_rename = numel(name_array);
for ii=1:num_files_to_rename
%in my test i used cells to store my strings you may need to
%change the bracket type for your application
curr_file = name_array{ii};
%locates the period in the file name (assume there is only one)
period_idx = findstr(curr_file ,'.');
%takes everything to the left of the period (excluding the period)
file_name = str2num(curr_file(1:period_idx-1));
%zeropads the file name to 3 spaces using a 0
new_file_name = sprintf('%03d.tiff',file_name)
%you can uncomment this after you are sure it works as you planned
%movefile(curr_file, new_file_name);
end
the actual rename operation movefile is commented out for now. make sure the output names are as you expect before uncommenting it and renaming all the files.
EDIT there is no real error checking in this code, it just assumes every file name has one and only one period, and an actual number as the name
The Batch file below do the rename of the files you want:
#echo off
setlocal EnableDelayedExpansion
for /F "delims=" %%f in ('dir /B *.tif') do (
set "name=00%%~Nf"
ren "%%f" "!name:~-3!.tif"
)
Note that this solution preserve the same order of your original files, even if there are missing numbers in the sequence..
I have two text files that I need to compare by date/time modified (not by its contents).
Source text file is at N:\folder1\source.log and the other is at C:\folder1\dest.log. If two text files are the same exit, if there not the same run N:\folder1\copy.bat
Basically, I have various files contained inside "folder1" in both locations in which i want the vbscript to only check the log file if the same. The batch file will simply copy and overwrite all files, making everything updated.
You need a FileSystemObject for file access, the .DateLastModified property of the files to compare, and the = (equal) operator:
>> t1 = goFS.GetFile("calibre.log").DateLastModified
>> t2 = goFS.GetFile("tmp\calibre.log").DateLastModified
>> WScript.Echo t1, t2, CStr(t1 = t2)
>>

I'm trying to set up a simple backup process for a folder on my C drive that will back that folder up to another location on the network. I know how to create a scheduled task but I'm struggling to understand why my command prompt code won't work - I'm a novice when it comes to the Command Prompt though!
So my question is two fold:
Why does echo %variableName% not return the variable value - it only returns %variableName%.
This is what I type in:
#echo off
set varA = 5
echo %varA%
%varA% <- This is what its popping out
Do I need different preceeding and succeeding characters for this?
I want to create a folder with the date for the name (I do realize that are quite a few questions out there on this but they didn't work), how do I do it?
Here is what I tried:
set folder_name = %DATE:/=_%
set folder_name <- Display value for folder_name
folder_name = Wed 11_06_2013 <- Actual value
When I try to do this:
mkdir %folder_name%
dir
Creates a folder with this %_date% as the name.
Where am I going wrong?
Thanks
Space is significant in SET statements.
SET varspace=spacevalue
will set a variable named "varspace" to "spacevalue"
Remove the spaces and it should be plain sailing...
Oh - except that if the variable contains a space, then commands such as MD or mkdir (which are synonyms) require "rabbits ears" around the value, thus:
mkdir "%folder_name%"
