You can use cheat sh web service to show cheatsheets for all kind of commands. Just replace the command name:
curl -s cheat.sh/date
. I also wrote a a simple script with filename being just a question mark to get a working command as?
, that shows all commands infzf
menu if no argument is given or shows the cheatsheet in the less pager if command name is given.Usage:
? ? -l ? date ? grep
#!/bin/env bash cheat='curl -s cheat.sh' menu='fzf --reverse' pager='less -R -c' cachefile_max_age_hours=6 # Path to temporary cache file. If your Linux system does not support /dev/shm # or if you are on MacOS, then change the path to your liking: cachefile='/dev/shm/cheatlist' # GNU+LINUX # cachefile="${TMPDIR}/cheatlist" # MacOS/Darwin # Download list file and cache it. listing () { if [ -f "${cachefile}" ] then local filedate=$(stat -c %Y -- "${cachefile}") local now=$(date +%s) local age_hours=$(( (now - filedate) / 60 / 60 )) if [[ "${age_hours}" > "${cachefile_max_age_hours}" ]] then ${cheat}/:list > "${cachefile}" fi else ${cheat}/:list > "${cachefile}" fi cat -- "${cachefile}" } case "${1}" in '') if selection=$(listing | ${menu}) then ${cheat}/"${selection}" | ${pager} fi ;; '-h') ${cheat}/:help | ${pager} ;; '-l') listing ;; *) ${cheat}/${@} | ${pager} ;; esac

This is pretty cool!
It works in Termux on Android too, you just need to uncomment the MacOS/Darwin cachefile line
