Preview

# {} is replaced with the single-quoted string of the focused line
fzf --preview 'cat {}'

fzf --preview 'bat --style=numbers --color=always --line-range :500 {}'

fzf --height 40% --layout reverse --info inline --border \
    --preview 'file {}' --preview-window up,1,border-horizontal \
    --color 'fg:#bbccdd,fg+:#ddeeff,bg:#334455,preview-bg:#223344,border:#778899'

Using Ignore

# Feed the output of fd into fzf
fd --type f | fzf

# Setting fd as the default source for fzf
export FZF_DEFAULT_COMMAND='fd --type f'

# Now fzf (w/o pipe) will use fd instead of find
fzf

# To apply the command to CTRL-T as well
export FZF_CTRL_T_COMMAND="$FZF_DEFAULT_COMMAND"

Examples

• custom hotkeys for git completions

# todo: also set default FD env vars, making this query simpler
fd | 
fzf.exe --bind 'ctrl-d:reload(fd -t d),ctrl-f:reload(fd -t f)'
