From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I've only ever found a use for sed once two decades into my career, and that was to work around a bug due to misuse of BigInt for some hash calculations in a Java component; awk remains unused. Bash builtins cover almost everything for which I find those are typically used.
find and grep see heavy daily use.
That's wild to me, as I used sed all the time. Quickly and easy changes in configs? Bam sed. Don't even need to open vi when I can grep for what I need, then swap it with sed. Though I imagine more seasoned vi nerds would be able to do this faster.
If you're using
findall the time, check to see if you have or can have some variant oflocateinstalled. It indexes everything* on the system (* this is configurable) and can be queried with partial pathnames, even with regex, and it's fast.I use locate when I don't know where the files are. Find has finer controls and can differentiate between regular files, links, directories, etc.
sedis not for daily use, it is for reusable scripts. For other purposes interactive editors are more convinient.
