Thanks in advance for the help.
I'm looking for a binary executable to convert an .arff into a .csv in a bash script. Ideally something that I could run along the lines of
#! /bin/sh
... some stuff....
converstionFunc input.arff output.csv
... some more stuff ...
Looking into writing this myself I found that weka provides a library that I could utilize that would allow me to do this. However, as much as I looked for it, I could not find it. I have weka installed on my mac and after looking around for the library I still was unable to find it.
Does anyone know where I may find such an executable, or able to point me where I could get a hold of the weka java library that would let me write it myself?
Clone this github repository. It contains an arff2csv tool in the "tools" subdirectory.
arff2csv is designed to run in pipes of unix commandline tools.
https://github.com/jeroenjanssens/data-science-at-the-command-line
arff2csv is a one-line shell-script that calls another shell script that calls weka.jar,
so it needs java installed on your machine; and note that arff2csv needs Weka version 3.6. (According to my experiments the newer v3.7 does not work.)
The script wants this environment variable set:
export WEKAPATH=/path/to/wekajar-dirname
and then you can do
cat /opt/smallapps/weka-stable/data/breast-cancer.arff | arff2csv > breast-cancer.arff.csv
Large arffs need some time to get processed.
You can read J.Janssen's book (see repo-README) for a bit more info.
Try an web search for arff2csv. It looks like there are lots of utilities out there.

When using XCode to compile a Cocoa application, I'm running a custom Bash script in the build phase. Unfortunately, I'm having to spell out full paths. Instead, I'm almost certain there are variables I can use in the Bash and one of those might cover it. Here's what I'm running:
/Users/mike/Projects/objectivec/proj1/proj1/shellscript.sh /Users/mike/Projects/objectivec/proj1/proj1/proj1/lang/en/html/
See how having a $VAR would help here, rather than specifying physical paths? It would also help members on my team be able to compile this project without modification.
I tried looking in the XCode7 docs, but couldn't find any listing anywhere of what these variables might be that I can use.
Note that the path /Users/mike/Projects/objectivec/proj1/proj1/ folder contains my AppDelegate.mm file in this case, if that helps you.
Can you tell me where I can find the documentation on this list of available variables so that I don't have to specify full physical paths?
The fix was that I made it run this Bash script as a test:
#!/bin/bash
set > /tmp/vars.txt
Then, I compiled a build. After that, I looked in /tmp/vars.txt to see what was available to use. From there, I could use these directly both in my custom Bash script and in the black script field inside XCode, such as $SOURCE_ROOT.
I want to generate the binary file.bin and I thought that it is possible in Vivado 2014.3 IDE
It seems like the command promgen doesn't exist?
How can I get an appropriate binary to use later in parallella board , it should have the header file
To generate a .bin file from the tcl console, the command you're looking for is write_bitstream which is documented in the Vivado Design Suite Tcl Command Reference Guide.
As #Paebbels mentioned there may be a way to use the promgen command from the command line (its not a tcl command), but I haven't ever tried that so I'm not sure. You can run the equivalent of the promgen tool (I believe PROMGen was an ISE tool) through the GUI if you connect to a device in the Hardware Manager (no longer called iMPACT in Vivado).
Finally if you need to create a .mcs file in a Tcl script you can use the write_cfgmem Tcl command (see the reference guide for more info).
I have a book called Beginning Lua Programming which is suppose to go over the raw basics but it is sort of leaving me stranded. Here is an effort to condense 3 pages:
QUOTE:
The following environment variables are recommended for Windows:
UTIL_DIR=c:\program files\utility
LUA_DIR=c:\program files\lua\5.1
LUA_CPATH=?.dll;%LUA_DIR%\?.dll
LUA_PATH=?.lua;%LUA_DIR%\?.lua
The UTIL_DIR variable identifies the utility directory you created in the preceding section.
After this, there is a segment about setting the 'windows search path' for lua. Basically, it tells me to look up the output of 'doskey /?' and 'path' and figure it out myself. I have no idea what these do, how to use them, and what the difference between them is.
I'm at my wits end. A detailed explanation or a link to a detailed blog/article or youtube video is EXTREMELY appreciated!
There are a few ways to get Lua working on your machine. If you just want to a functional Lua environment in a hurry with minimal fuss then consider downloading one of the precompiled Lua binaries. The common ones being Lua for Windows and LuaBinaries.
Building Lua with Mingw isn't too difficult:
First get your desired Lua version here.
Extract the tar file containing Lua's source somewhere. For this example, I'll assume you extracted to c:\lua
If you have Msys already set up, you can run the make file from that environment. From the Msys shell, you can build lua with the follow commands:
cd /c/lua
make PLAT=mingw
make install
You should find lua.exe and luac.exe somewhere in there after the build completes. Lua should be ready for use at this point.
The regular cmd.exe shell can work too with some changes to the commands:
cd lua
mingw32-make PLAT=mingw
The make install assumes a *nix environment and so doesn't work under a normal windows cmd shell. In this case you can just manually copy the compiled files from .\lua\src to where you want or you can just run it directly from there if desired.
I have a ruby program named options that I want to run from the command line with a few options like
options -add 400
options -sub 600
options -h
I am already using optparse to interpret the commands but I want to run the program as its own script, but have to run it as
ruby options -add 400
I've looked it up and found some answers like How to create a shell command supporting Ruby? which seems to be linux and I'm not sure of part of the explanation like which bin to put in, or answers like Shell execute from Ruby whose answer still requires ruby in the command. Can anyone explain how to do this in more depth, or direct me to a source that explains it without relying on a linux platform?
Assuming that you have ruby in your PATH on Windows couln't you just create wrapper script and place it in folder present at your PATH?
ruby options %*
Do you have thought about to make it as gem ? There is a simple guide http://guides.rubygems.org/, then you can make the gem which will be working on linux and windows too. I don't know if you know but when I did software avaible under shell or bash I used slop (https://github.com/injekt/slop) it is very convenient the gem. Please see the source of slop, because it is an example of gem, all structure and necessary files to build the gem.
Is there a way that we can write automation scripts in bash syntax and run it on Windows host (We can call the executable file .exe of Windows). The Windows batch syntax looks quite complex :D
Any suggestions are appreciated.
You can use cygwin or mingw sys for this.
They are both just BASH implementation available on WinXX (actually they are much more, but you need now only bash).
But there are some differences:
cygwin uses its own file system hierarchy, with Win drives mapped to a part. subdirs. All related to file names is more unix-style. There are some problems with passing pathnames to Windows programs.
MinGW is more Windows friendly, file paths are like in Windows, less problems with Windows native programs.
You should try yourself and choose what you need.
You could install cygwin and run bash.
You can get a win32 port of bash. Cygwin is enormous, but native windows bash and a few utilities can be had for a much smaller footprint.
Start with UnxUtils, which includes a sh based on zsh (it's quite slow, though).
If that's not enough you can get a win32 bash from some places, though most are older versions.
