For many, many years now when I want to browse a man page about something I'll type man X into my terminal, substituting X for whatever it is I wish to learn about. Depending on the manual, it's short and therefore easy to find what I want, or I am deep in the woods because I'm trying to find a specific flag that appears many times in a very long document. Woe is me if the flag switch is a bare letter, like x.
And let's say it is x. Now I am searching with /x followed by n n n n n n n n N n n n n n. Obviously I'm not finding the information I want, the search is literal (not fuzzy, nor "whole word"), and even if I find something the manual pager might overshoot me because finding text will move the found line to the top of the terminal, and maybe the information I really want comes one or two lines above.
So... there HAS to be a better way, right? There has to be a modern, fast, easily greppable version to go through a man page. Does it exist?
P.S. I am not talking about summaries like tldr because I typically don't need summaries but actual technical descriptions.
rsync - a fast, versatile, remote (and local) file-copying tool
--append-verify --append w/old data in file checksum
--progress show progress during transfer
--archive, -a archive mode is -rlptgoD (no -A,-X,-U,-N,-H)
--verbose, -v increase verbosity
--compress, -z compress file data during the transfer
--rsh=COMMAND, -e specify the remote shell to use
There is a Plugin for Zsh (ohmyzsh) that gives you that right in the shell. I use it all the time and rely on it.
Don't have the name on my mind though, sorry.
I have to remember to use tldr, one of these days. Some manpages get so lost in the pedantry of covering everything that the 99 percentile stuff is buried.
+1, displaying in a Emacs buffer solves any issues I could have. If you're already 'in' Emacs, this will be more frictionless than shell scripts around man
You can set on what line on the screen less (the pager program man uses by default) puts search results with the -jn/--jump-target=n option. For example, using .5 as a value for n makes less focus the line with the search result on the center of the screen. This should help with your overshoot issue.
Either set the option within less with the - command followed by j.5↵ for the current running instance of less, or set and export the LESS environment variable inside your ~/.bashrc to have less always behave that way.
man -k printf
Search the short descriptions and manual page names for the keyword
printf as regular expression. Print out any matches. Equivalent to
apropos printf.
Sorry it's not a very direct answer but this is one of the many things that make Emacs such a comfortable environment once you're used to it, which takes ... a while.
There is a man command and then of course it's just more text displayed so you can search and narrow and highlight etc. in the same way you do with any other text. Plus of course there are a few trivial bonuses like links to other man pages being clickable.
It's all text and Emacs is a text manipulation framework (that naturally includes some editors).
the / and ? commands in the pagers more and most less implementations should support regular expressions (usually BREs in my experience); which is the same thing grep uses. Consider reading your friendly neighborhood regex formatting manpage, if you are confused. As for easily scrolling, ^G to terminate your search followed by b (or your favorite vi or emacs scrolling bind) to scroll back should be sufficient.
Also, man some-manpage | grep expression works, if you didn't know.
You can search via regex. For instance you know a section heading or flag is the first thing on a line preceded with spaces. I also find it earier to read with extensions for colors.
I lately often use chatgpt for these kind of things. It's amazing in breaking down the parameters and what they mean. Verify, especially when the problem is hard and apparently unfindable. Chatgpt won't find it either. It sometimes makes up things in these scenarios.
