Linux Sed Tutorial: Learn Text Editing with Syntax & Examples
3 March 2025 @ 9:47 am
Sed is an acronym for "stream editor." A stream refers to a source or destination for bytes. In other words, sed can read its input from standard input (stdin), apply the specified edits to the stream, and automatically output the results to standard output (stdout). Sed syntax allows an input file to be specified on the command line. However, the syntax does not directly support output file specification; this can be achieved through output redirection or editing files in place while making a backup of the original copy optionally. Sed is one of the most powerful tools on Linux and Unix-like systems. Learning it is worthwhile, so in tHow to tell if FreeBSD needs a Reboot using kernel version check

How to control the SSH multiplexing with the control commands
15 January 2025 @ 8:29 am
Multiplexing will boost your SSH connectivity or speed by reusing existing TCP connections to a remote host. This is useful when you frequently connect to the same server using SSH protocol for remote login, server management, using IT automation tools over SSH or even running hourly backups. However, sometimes your SSH command (client) will not respond or get hung up on the session when using multiplexing. Typically, this happens when your public IP changes (IPv4 to IPv6 changes when using DNS names), VPN issues, or firewall cuts connections. Hence, knowing SSH client control commands can save you time and boost your productivity when such gotcZFS Raidz Expansion Finally, Here in version 2.3.0

How to run Docker inside Incus containers
18 December 2024 @ 5:44 am
Incus and Docker both use Linux kernel features to containerize your applications. Incus is best suited when you need system-level containers that act like traditional VMs and provide a persistent developer experience. On the other hand, Docker containers are ephemeral, i.e., temporary in nature. All files created inside Docker containers are lost when your Docker container is stopped or removed unless you stored them using volumes in different directories outside Docker. Docker is created as a disposable app deployment system. Incus containers are not typically created as disposables, and data is kept inside heartinternet.co.uk
