I have a simpler solution. The use case is not precisely the same, but for many scenarios, it's effectively the same. Simply, like many, I have bash set up to record commands in .bash_history. I have it flush all the time, so .bash_history is always current. # keep persistent bash history across sessions export PROMPT_COMMAND='history -a;history -n' export HISTCONTROL=ignoredups shopt -s histappend Next, I have a sim…

Yep, history is my go to Rosetta Stone for remembering other commands.

Anytime I sign into a system I have not signed into for a long time. The first thing I do is save the history file before I start working. Many times it has saved the day when you get stuck: where did I store that config? what was the command to restart the server?

(Unrelated to original post) That only helps if you know the keywords curl and json. My actual problem in the past has repeatedly been that I a) forget how the graphical file manager on my system is called because I use it a couple of times per year (dolphi, konqueror, thunar, whatever...) and b) I use i3 or xmonad and don't have a "start menu" to just browse.

I think I should just put a symlink called explorer.exe in my ~/bin/ and then I know where to look ;)

Earlier quoted context omitted.

Apropos has the compelling feature that I get to feel clever for knowing the word.

I believe man -k just runs apropos.

Right. There's often a tension between features and ease of use.

Some people seem to be unaware of apropos too (old text based cli tool). $ apropos network interfaces (5) - network interface configuration for ifup and ifdown aseqnet (1) - ALSA sequencer connectors over network byteorder (3) - convert values between host and network byte order ctstat (8) - unified linux network statistics

I hate that it spews so much irrelevant things. Run "apropos directory" on macos and see if you can find "ls" between

create_automation_image_overlay(8), -(8) - ."====================== create_automation_image_overlay overlay automation image content onto another directory ." ."

and

CPANPLUS::Internals::Source::Memory(3pm) - In memory implementation n .SS "$cb->_|_memory_retrieve_source(name => $name, [path => $path, uptodate => BOOL, verbose => BOOL])" .SS "$cb->_|_memory_retrieve_source(name => $name, [path => $path, uptodate => BOOL, verbose => BOOL])" Subsection "$cb->__memory_retrieve_source(name => $name, [path => $path, uptodate => BOOL, verbose => BOOL])" This method retrieves a storabled tree identified by $name. It takes the following arguments: name" 4 Item "name" The internal name for the source file to retrieve. uptodate" 4 Item "uptodate" A flag indicating whether the file-cache is up-to-date or not. path" 4 Item "path" The absolute path to the directory holding the source files. verbose" 4 Item "verbose" A boolean flag indicating whether or not to be verbose. Will get information from the config file by default.

man -k has been working just fine for me for 30+ years

TIL about the -k option. Whoa.

Hey guys, I've created a really small tool that converts natural language into terminal commands using GPT3. To my chagrin, I seem to have a pathological inability to remember commands so I'm hoping this may help others suffering from such a terrible affliction.

When I first read this comment I assumed it was someone sarcastically pretending to be the creator and not the actual creator, and I thought, what a dick... LOL

Looks neat! I've already been using github copilot which I've found brings some more joy into coding (even when it's a little off).

Nice work, I wanted to add how I deal with this. first my .bashrc Is setup to append and history is set to 100,000 lines.

Most importantly I have an alias set up for the letter h , that greps, case insensitive .bash_history. ( grep -i $1 .bash_history ).

So typing in the cli: # h awk gives me all my awk commands.

And second , as a global history search across all my VMs/instances, (as I already make extensive use of splunk and splunks universal forwarder log forwarding app/tool) , all vms have their splunk universal forwarder service set to send any updates to .Bash_history to my central spunk server. thus I’m able to globally search the bash history from any VM globally, going back forever (I search that via the splunk web gui i mean). All works great!
