Link: How to Clear Spotify Cache

If you have been a regular user of Spotify (on desktop), you should know that it caches your playlist in the local hard disk so it can quickly playback the songs without having to stream from their server again. However, if you are running low on hard disk space, you might want to clear the cache to make way for more important documents. The Spotify desktop client doesn’t come with a way to clear the cache. Here is how you can clear Spotify cache in Windows, Mac and Linux.

Link: 5 Reasons Why PCLinuxOS Is Better For Windows XP Users Than Ubuntu

I have recently written a series of articles showing How to install PCLinuxOS alongside Windows XP.

There are a number of reasons why I chose to write about PCLinuxOS over say Ubuntu or Linux Mint.

Here are five reasons why I think PCLinuxOS is a better fit for Windows XP and Windows Vista users than Ubuntu.

Link: Grep command in linux – Get a grip on it

Linux was created by software enthusiasts who wanted to make it available to all for free. The source code was also kept open so that anyone can contribute to it. A Linux loving community was formed which worked on it relentlessly to make it a strong and robust operating system. These people have added commands that made Linux very powerful and popular.

Grep is one such command in Linux which as a user you will find very helpful. Let us see how grep can be used to make your work easier. We assume you have a basic knowledge of Linux. If not, we recommend you first go through this simple Linux crash course.

Link: Linux/Unix: pstree Command Examples: See A Tree Of Processes

I am a new Linux user. How do I display the process on the Linux based server or desktop/laptop in easy to read tree format using bash shell prompt?

Linux and Unix are multitasking operating systems i.e. a system that can run multiple tasks (process) during the same period of time. A process is nothing but a running program (command) on Linux or Unix-like systems.

The pstree command shows running processes as a tree.

Link: Linux Terminal: Poor Man’s Spotify (actually works with Windows, Linux, and Mac OS X)

While I was looking some video related to Linux I’ve found this video of gotbletu an user that I follow on Youtube, related to a small player to listen music directly from the terminal: pms AKA Poor Man’s Spotify.

I like lightweight clients, and so I’ve gave it a try, these are the results.

Note that this is a Python script, and therefore should run on any platform that has Python 2.7 or 3 installed.

Xvidtune: a Linux command line interface to print or switch the video mode and/or interactively adjust existing video modes

From the Ubuntu manuals page for xvidtune – video mode tuner for Xorg:

Xvidtune is a client interface to the X server video mode extension (XFree86-VidModeExtension).

When given one of the non-toolkit options, xvidtune provides a command line interface to either print or switch the video mode.

Without any options (or with only toolkit options) it presents the user with various buttons and sliders that can be used to interactively adjust existing video modes. It will also print the settings in a format suitable for inclusion in an xorg.conf file.

Normally the Xorg X servers only allow changes to be made with the XFree86-VidModeExtension from clients connected via a local connection type.

Note: The original mode settings can be restored by pressing the ‘R’ key, and this can be used to restore a stable screen in situations where the screen becomes unreadable.

Emphasis added. We had not heard of Xvidtune before, and it seems like it could be a handy tool to have in certain situations. See the manual page for your Linux distribution, or the Ubuntu manuals page for xvidtune for additional information. However, Tecmint warns:

Note: The Incorrect use of this program can do permanent damage to your monitor and/or Video card. If you don’t know what you are doing, don’t change anything and exit immediately.

Link: Linux Terminal: sshfs, Remote directory over ssh

Often one wants a shared access to files across machines. Traditionally one uses the network file system (nfs). The network file server works as follows: There is an nfs server that exports some directories in its filesystem hiearchy to various nfs clients that mount these directory over the network into their file system hierarchy. As a result, each of the clients shares the directories exported by the nfs server.

However a lot of times you just have to mount a directory from a server to your local computer and in these cases NFS it’s not so useful, sshfs it’s much better

Sshfs is a filesystem client based on the SSH File Transfer Protocol. Since most SSH servers already support this protocol it is very easy to set up: i.e. on the server side there’s nothing to do.  On the client side mounting the filesystem is as easy as logging into the server with ssh.

Link: How to run “unkillable” programs in Linux

Here is a neat trick. If you want to start a program that always respawns if it gets killed, just put it in /etc/inittab. The init process will respawn the program. That’s what it’s for.

Here’s an example. …

Link: Remotely Working Together on a Terminal Session in Linux

I often get a chance to work from home, and this has given me opportunities to look for ways to share sessions with my colleagues. Windows XP used to have the excellent NetMeeting tool, but I recently switched to Ubuntu and haven’t yet found an equivalent.

Yes, I’ve heard of VNC and used it a lot too, but I wasn’t happy with its remote desktop sharing performance. Ekiga is interoperable with NetMeeting calls, but doesn’t support screen sharing. Even Skype’s screen sharing does not seem to support remote screen controlling.

However, Linux’s power is at the command line, and this is true even in the case of remote sharing. So here comes screen to the rescue – this magical command allows you to flawlessly resume lost sessions and share them with multiple users at the same time.
