The default Vim plugin directory structure under ~/.vim is inherently messy. Without a plugin manager, files from different plugins scatter across autoload/, plugin/, ftplugin/, colors/, and other directories, making it difficult to track which files belong to which plugin. Removing a plugin requires manually hunting down and deleting its files across multiple locations. Several plugin…
Vim ships with built-in completion that many people don’t fully leverage. Before reaching for plugins, understand what’s already available: Ctrl+N / Ctrl+P: Basic keyword completion from open buffers and loaded files Ctrl+X Ctrl+F: Filename completion Ctrl+X Ctrl+]: Tag completion (requires ctags) Ctrl+X Ctrl+O: Omnicompletion (language-aware, when available) The omnicompletion (Ctrl+X Ctrl+O) is what resembles IDE…

When a disk fails on a server with multiple drives, you need to identify which physical SATA port it’s connected to. Linux device names (sda, sdb, etc.) don’t necessarily map to SATA port order, especially after disk failures or in systems with mixed storage. Using lsblk with Device Paths The lsblk command provides a quick…
When you modify /etc/sysctl.conf, the changes take effect on the next reboot. To apply them immediately without rebooting, use the sysctl -p command: sudo sysctl -p This reads the configuration file and applies all settings to the running kernel. Reloading Specific Configuration Files By default, sysctl -p reads from /etc/sysctl.conf. You can specify a different…
Working in an SVN repository often leaves behind temporary build artifacts, compiled outputs, and editor cache files. Unlike Git’s git clean command, SVN has no built-in cleanup mechanism for untracked files. Using svn st to Identify Untracked Files The svn status command (or svn st) marks untracked files with a ? prefix. You can leverage…

Linux can manage multiple swap partitions or files simultaneously, each with an assigned priority. The kernel allocates swap pages from highest to lowest priority, with round-robin allocation among equally-prioritized areas. Setting Swap Priority with swapon Use the swapon command to activate a swap partition and set its priority: swapon -p 10 /dev/sdc1 The -p flag…
Swap space is essential for system stability, allowing the kernel to move less-frequently-used memory pages to disk when physical RAM is exhausted. Here’s how to set up a dedicated swap partition. Step 1: Create the Partition Use fdisk, gdisk (for GPT disks), or parted to create a new partition. For modern systems with GPT partition…
