I would like to backup a dir in Win XP on a Solaris server via rsync. I installed cygwin but when I type rsync I get 'command not found'. How can I install rsync? And how can I install ssh. I have installed Poderosa as ssh client (a sort of putty).
run your cygwin setup.exe again, and expand the categories to find 'rsync' and 'ssh'.
Much easier. Run setup, click through to the 'Cygwin Setup - Select Packages' window, and type 'rsync' in the 'Search' box at upper left. At this writing, this shows three lines, one of which is 'Net'. Expand Net and you'll find rsync. Click the circular arrow icon to mark it for install, then click Next at lower right.
You still need to install the rsync package. Run setup.exe again and go through the packages manually (it's probably in 'networking' or 'utilities').
When you run setup.exe, the package selection will be set to "default". You need to click on the top-level circular arrow picture until it says "Install" or "Full" (my memory fails me), it will do this for all sub-packages as well.
The first time you click on it, wait a few seconds - there's a long delay in getting from "default" to the next option.
That's the best way. All the times I've tried to select individual packages, I've had troubles so I've long since gotten into the habit of installing everything.
If all you want is rsync, the BackupPC project (OSS) has a slightly modified version of cygwin's rsync that runs without a full cygwin installation, and can even be installed remotely on PCs with IPC$. http://sourceforge.net/project/showfiles.php?group_id=34854&package_id=88133

I don't want to install multiple instances of perl.
How can I upgrade my Perl to latest version or delete existing Perl installation and install a new version of Perl in Ubuntu 14.04.
After new installation, will it conflict with older installation files.
I'd do it like this:
wget http://www.cpan.org/src/5.0/perl-5.22.1.tar.gz
tar xvfz perl-5.22.1.tar.gz
cd perl-5.22.1 && ./Configure -Duseithreads -des && make && make test && make install
/usr/local/bin/cpan -u
This puts a source build of perl in /usr/local/bin
Then check your path has /usr/local/bin in it, and if you want typing perl to run your new perl, ensure it's in front of /usr/bin (this is a fairly common scenario, but I can't say for sure if that applies.
Whilst you say you don't want to install multiple perl versions - this is a bad idea.
perl is distributed as part of your operating system. Packages depend upon it, and the particular version. You cannot tell what you might break by altering versions - not least because the way perl handles certain things does change between versions (like hashes).
Messing around with /usr/bin/perl is a road to some future pain (not least - it makes an 'update' of your OS annoyingly difficult, because you can no longer use the package manager without a bit of hackery)
If you REALLY REALLY want to do that you can set -Dprefix= in your Configure options. But as a sysadmin of 15 years experience, I can tell you - no good will come of it, you will break your OS in a variety of minor, but cumulatively really annoying ways. (And maybe some bigger ways)

After booting linux in purly command line mode how can I open an application eg web browser or Libra Office?
For example if I use the command "play" with any audio file it starts to play it. I want to know commands for other applications
You have to start an X Window session before you can open those applications because they depend on it to render the GUI. To do this you can use the startx command.
There is a good description here on how to use startx.
However, doing it this way can be a lot of manual and tedious work. That's why most linux distros have packaged full window managers like Gnome, Xcfe, etc for you to install with a single command. If what you really want is a minimal one you might look at Fluxbox or Openbox. You can learn a lot about the guts of X by installing and configuring them on your own.
I suspect what you may really need is just to edit text files and get resources from the internet while logged into a Linux box that is command line only. If so, you can check out these command line only tools.
Lynx command line browser
WGet internet file retriever
EMacs text editor
Vim text editor

This question arose in my mind while I was installing JDK on Ubuntu. While I was installing JDK the steps are -
Extracting the .bin file of java.
Make a directory named java6 in /usr/lib and move all the content of extracted .bin file to the /usr/lib/java6.
Now soft a soft link is created in the current directory like this-
ln -s java6 java
I am surprised that the newly created link 'java' is used to set "JAVA_HOME" environment variable. As far as I know a similar thing is not possible in Windows.
More over while I am installing nexus I noticed the following -
$ ln -s nexus-2.7-06-bundle nexus
$ cd nexus
$ ./bin/nexus console
What I am trying to say here is - first we access the link directory (nexus), then we are running script (in /bin/nexus). I noticed these two approaches in several tutorials. I think these approaches should have some benefits.
Now my questions are that -
Why a link (/usr/lib/java) is set as JAVA_HOME; what is the advantage of doing so?
Why we are running the script (... /bin/nexus) from going to the soft link directory and what is the advantage of doing so?
When I am using the base directory instead of the link for the mentioned two cases, it also works fine. So, why these approaches?
If you install java7 instead of java6 (or java7 parallel to java6
or something else like that), if the JAVA_HOME variable and 100 other things are set
explicitly to java6, you would have to change them all to java7.
(and it is not trivial to find all config stuff which need changes).
With the link, you set all config stuff to the link and change only the link if necessary.And yes, this is possible on Windows too.
1) Why a link (/usr/lib/java) is set as JAVA_HOME; what is the advantage of doing so?
JAVA_HOME points to java you want to use (say java6)
JAVA_HOME is just a convention, usually software like eclipse, maven etc... use it to find where Java is located.
And yea it can be done in Windows too.
2) Why we are running the script (... /bin/nexus) from going to the soft link directory and what is the advantage of doing so?
Advantage none (It depends on you how you see it)
This Q is somewhat similar to Q1..
Say in future you want to use new version nexus-2.8-*. So instead of changing all configuration from nexus-2.7-* to nexus-2.8-*; you can just change the soft link nexus(to point the new version)
3) When I am using the base directory instead of the link for the mentioned two cases, it also works fine. So, why these approaches?
You answered you own Q!
Yep its a link; so nexus --> nexus-2.7-06-bundle; one and the same...
why the approach? see 3rd point of previous Q
Think of soft link as shortcut in Windows

When I am using Awesome-WM under Linux Mint 13 "Maya" MATE, sometimes I need to open the File Manager "Caja". But when I launch caja, the wallpaper changes to the one I set under MATE instead of the one in rc.lua. I have tried
sudo gsettings set org.gnome.desktop.background draw-background false
but it seems useless.
How can I keep my settings under awesome-wm? Or I should set the 2 backgrounds the same?
You could try setting your wallpaper using feh.
Create a .fehbg file in your $HOME and put this in:
feh --bg-scale '/path/to/wallpaper.jpg'
..then save it.
Then in your autostart script just add sh $HOME/.fehbg & then try restarting your DE. If it still persists after opening Caja, then I am not sure about that since I am totally unfamiliar with Caja, rather, I am not familiar with MATE at all.
I think what's happening is that caja is set to 'manage' your desktop. That means it'll change your wallpaper to the one set in MATE, and probably display desktop icons as well, e.g., Computer, Home, etc. This has always been a problem for me when using alternative window managers on Ubuntu, because nautilus does it as well. With nautilus the behaviour can be turned off using the terminal flag --no-desktop. caja seems to be a descendant of nautilus and a quick Google shows references to the same terminal option for it as well. So I suggest you try
caja --no-desktop
and see if that works for you.

My KDE is broken, the desktop Widgets cannot be displayed. And many KDE programs look like this:
All the software written in GTK is all right.
Can any one give me any suggestion about what's happening and which part is broken?
Where can I find error log?
You don't say what disto you're using (please add it to the tags in your question), nor how you got in this state - new installation? dist-upgrade? hard crash? That would be useful information.
But in general, here's what I would try:
Log out and go to a bare terminal with CTRL-ALT-F1, then login and rename your .kde / .kde4 directories: mv ~/.kde ~/.kde.old and reboot or otherwise restart your GUI system.
That will at least tell you whether the problem is messed up personal settings or messed-up system files.
If that doesn't fix the issue (that directory will be recreated when you start up KDE again; all your settings will be lost, but you can recover them - carefully, one by one - from the backup you just made), then I would first try sudo apt-get check (assuming you're on a Debian-based distro).
If that doesn't report any problems, then I would update my system - possibly even do a dist-upgrade without changes any sources.
If this issue still wasn't fixed, I would run sudo dpkg -l > ~/Desktop/dpkg_out.txt to get a list of installed or uninstalled packages and their state in a file, and then look through the file for problems as explained here.
Finally, if all of that failed, I would take a good hard look at my video drivers.
Good luck!
