How to Get Available Filesystem Space on Linux: a C Function with a C++ Example
Monday, August 31, 2015 @ 10:35:38 UTC by lbadmin (87 reads)
Softwareericzma writes
How to Get Available Filesystem Space on Linux: a C Function with a C++ Example: It is common for programs to write to files in filesystems on disks. However, what if the disk was almost full when your program writes to the filesystem on a disk? For systems software and mission critical programs, it is a better or must-to-do practice to check the available filesystem space before actually writing to files. On POSIX OSes, we have the statvfs POSIX API to get filesystem statistics (On Linux, you may use the Linux specific statfs, but POSIX APIs are better for portability). In this post, we will introduce a C function and a C++ example to use the statvfs API to get the available filesystem space.

Controlling Filesystem Mounting on Linux by Playing with /etc/fstab

Linuxericzma writes
Controlling Filesystem Mounting on Linux by Playing with /etc/fstab: Controlling the mounting of filesystems is a useful technique for managing Linux systems. The mounting configurations are mostly in the /etc/fstab file. In this post, we will discuss 2 common and useful techniques for controlling the filesystem mounting by playing with the /etc/fstab file: allowing non-root users to mount/unmount filesystems and avoiding mounting failures blocking the booting of Linux. Continue reading: Controlling Filesystem Mounting on Linux by Playing with /etc/fstab at SysTutorials.

What Is the Name of the Linux-based OS: A Survey ? Fclose.com: You may already well know ?Linux? and may also use the ?operating system based on the Linux kernel? directly or indirectly (you are indirectly using it now as Fclose.com is hosted on Linux). But how should we name the OS based on Linux? You may know there is GNU/Linux naming controversy. Different people have different opinions about this. Today, let?s see how do these widely used distributions call themselves by looking at their ?about? web pages. Continue reading: What Is the Name of the Linux-based OS: A Survey ?

A PHP Function for Fetching RSS Feed and Outputing Feed Items as HTML ? Fc

A PHP Function for Fetching RSS Feed and Outputing Feed Items as HTML ? Fclose.com: I aggregated all my new posts from several sites into a single RSS feed. Last time I updated my homepage, I came across an idea why not showing these feed items directly on the homepage as HTML content. After some study, I got one single PHP function in my hand that fetches an RSS feed and outputs HTML content in the page.

Turning gnome-terminal to a Pop-up Terminal
Tuesday, February 03, 2015 @ 10:25:09 UTC by lbadmin (5880 reads)
HOWTOs and similar articlesericzma writes
Turning gnome-terminal to a Pop-up Terminal: A pop-up terminal is great and handy on Linux and similar OS. On KDE, Yakuake is great. On Gnome or GTK, I ever tried Guake. It is quite good. However, it has not been as mature, stable and figure-rich as gnome-terminal. One day, I got this idea: why not using a script/program to manage the gnome-terminal and take action upon hotkey hits? The top-down effect is non-important to me. What I want is simple: use a hotkey (like F12) to activate/deactivate the terminal.

Lazy Linux Admins Going to Server Rooms Less: Forced Reboot, Auto Reboot after K

Lazy Linux Admins Going to Server Rooms Less: Forced Reboot, Auto Reboot after Kernel Panic and Email Notification after Reboot: Having to go the the server room to reset servers is the most headache thing for admins managing a cluster of Linux servers in a remote site. Either you can ping the server but can not ssh to it, or you even can not ping it. There are various reasons that may cause a Linux server crash or fail to be connected to by SSH. The most common two from my experience are: there may be a bad behaving progress that use up almost all physical memory and swap or there may be a kernel panic. In this post, I describe several techniques I learned to make myself go to the server room less by dealing with these kinds of failures.
