Interactively search command options from man with fzf.
Copy manoptfzf.sh in $PATH and source it
manoptfzf() {
local dir
man $1 | sed -n "/^\s*-. /p" | fzf --preview "manopt $1 {1}"
}This function accept a command name and calls manopt.
I must use an extra function because fzf pass argument as single-quoted in --preview.
Copy in $PATH and make executable with chmod +x
fzf doesn't see my custom bash function in --preview, but an executable is fine.
whatis $1
man $1 | sed -n "/^\s*$2/,/^$/p"
