# Inspiration from: https://github.com/jorgebucaran/cookbook.fish#how-do-i-find-and-run-commands-in-fish

# Set $all_commands to a list of all commands available on $PATH
set -l all_commands (ls $PATH | column)

# Use `whatis` to append a one-line description of each command to a file
for p in $all_commands
  whatis $p | tee -a all_command_descriptions
end

# Pipe the results into fzf, use string to grab the command name, and pass to
# man for further investigation.
man (string trim (string split '(' (cat all_command_descriptions | fzf) | head -n 1))
