I have installed sbt as told in following statements:
Download sbt from here: http://scalasbt.artifactoryonline.com/scalasbt/sbt-native-packages/org/scala-sbt/sbt/0.12.4/sbt.tgz
Unpack the archive to a directory of your choice
Add the bin/ directory to the PATH environment variable. Open the file ~/.bashrc in an editor (create it if it doesn’t exist) and add the following line export PATH=/PATH/TO/YOUR/sbt/bin:$PATH
But, when I type scala in terminal, it says scala in not installed! Though, sbt -h works fine.
How to resolve the issue?
you have to run sbt consolecommand to run scala REPL from sbt.

I need to execute a program in my system using the perl.exe from a network path.what change should I have to change in the interpreter line to execute that..?
There's a fair chance (given that the question gives us no clues to help us answer it) that the perl.exe is just a wrapper for perl.dll, so if the perl.exe isn't on the path (and it won't be if its on a network share) then the exe will fail to run.
The answer is almost certainly to copy the required files locally and run them there. I recommend Strawberry Perl for Windows, as its just a directory copy to get it installed.
Invoking using a remote exe may not work due to the exe's own dependencies. Consider packaging your perl script as an exe using http://search.cpan.org/dist/PAR-Packer/

I have downloaded Net-SSH2-0.43 to be able to use Net::SSH2 Perl module. But I don't know what I need to do after that, just include paths or something else. Please help.
you could use perlbrew to install Perl in your home or in any directories wo. root rights: http://perlbrew.pl/
wget -O - http://install.perlbrew.pl | bash
perlbrew install perl-5.16.0
perlbrew switch perl-5.16.0
you could call your perl from shell (scripts) like this: http://perlbrew.pl/Perlbrew-In-Shell-Scripts.html
If your servers are identical enough then you could rsync/rdist this directory to every host and you are done.

I used maven to download mahout and hadoop recently. Because I could not seem to do that without using sudo mvn commands, eclipse could not seem to be able to use anything I had downloaded (there were lots of errors like parents of things like POM.xml being permission denied etc.) and more recently than that I was trying out mahout (with local jars downloaded directly from one of apache's mirrors, not from maven) and although I could run the class the first time, I couldn't do it again because my eclipse instance could not overwrite the file I had already written.
These are just examples of times I feel it would have been good to be running eclipse as superuser by doing
sudo eclipse
Instead of just launching it normally. The only problem I can think of is that as root eclipse suggests you use the root/workspace, but is it ok to just tell it to use yourusername/workspace?
In general- no. It's tempting, but not very good practice to do all of your development as the superuser. If you're running Eclipse as root, then you're also launching Java processes as root when you run your software. (You could change your Java run settings to sudo back to a regular user before running, but I wouldn't recommend that as a solution).
In addition to being a security risk, you are also making it difficult to track down bugs if you want to distribute the software to others to run as non-root (e.g. doing root only things like reading a protected file or using a well known port might work for you, but not for the average user).
I recommend finding the files that are causing issues and doing chmod o+r on them.

How can i locate my project in terminal which i created in xcode?
How can i add or install Submodules of Sharekit to my project?
I am trying to locate my project created in Xcode.
When i type in locate abc.xcodeproj
it gives this warning
WARNING: The locate database (/var/db/locate.database) does not exist.
To create the database, run the following command:
sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.locate.plist
Please be aware that the database can take some time to generate; once
the database has been created, this message will no longer appear.
Thanks for help.
locate is somewhat obsolete. Use Spotlight instead:
$ mdfind abc.xcodeproj

I'm using Cygwin 2.769. I used setup.exe to upgrade Perl to version 5.14.1-2, which works fine. But now whenever I open setup.exe to upgrade/install some other package, it by default wants to downgrade Perl back to 5.10.1-5. If I don't remember to manually cycle that box over to my current version each time, Perl gets downgraded without my noticing.
Is this expected behavior, or have I hosed something up? It seems like using the "Curr" setting should not by default downgrade things.
I've had this problem, and it's made package managers almost unbearable. When disparate packages want to rely on different versions of a package that can only install in one version at a time, bad things happen.
Don't use the system perl for anything. Install a perl that other packages don't care about.
