No. You
grep
if you are searching for something. Yoused
when you're editing a file in an automated manner. You usecp
if you copy a file.cat foo > bar
is not, in the very slightest, idiomatic, and never was:cat foo bar > baz
is and that's precisely whycat
is named like that, quoth the man page: "cat - concatenate files and print on the standard output".cp
can't do that. If you usecat
with a single argument then without redirection, as the equivalent of DOS'stype
.Don't think of "one thing, and one thing well" as "there must be no overlapping features", but "every program has a clearly-defined use case". If it can be used for something else, like single-argument cat, then that's fine, but that doesn't make cat the program to use when copying files.
And it means "there must be no overlapping features when combining random programs in arbitrary ways" even less: Your
cat foo > bar
uses two programs,cat
andsh
. If the combination between multiple programs was restricted to not have features available elsewhere then you wouldn't get any of the benefits of being able to combine programs, this explosion of possibilities and with that approaches is precisely the advantage of combination.Never heard of silversearcher, but ripgrep is a straight-up grep replacement. Grep is 50 years old, ripgrep takes 50 years of experience people had with using the original to design a program that fulfils grep's purpose even better. There's no council of greybeards saying "there already is a program like that you shall use, we can't have two programs doing the same thing", that's not Unix but python.
I tend to agree. I use nushell, haven't really gotten into ripgrep I probably just don't grep often enough to care. My editor is helix which breaks in may ways with the line that started with ed but keeps the core philosophy intact, nay, adheres better to it because it was bold enough to get rid of hysterical raisins. As ripgrep it's an iteration of the same core idea and principles of an old program, in the light of 50 years of experience people had using it.
You could also combine a text editor and maybe pandoc. Different notes? Different files, that's what the file system is for. Need to find something in your notes? grep.
You'll be hard-pressed to find an actual use-case for a simple note-taking app under unix because the combination of things everyone half-way acquainted with the system already does it. There's org mode, yes, but org mode isn't simple. Also emacs is a completely different operating system.
