fzfのための関数書いた

概要

gitを真面目に使い始めたらなぜかfzfの便利さに目覚めたので関数書いてもっと便利にしたかった

コード

基本的な関数はワンライナーに組み込みやすいようにfzfの引数に$@を渡す。

xargsの-rオプションは入力がないときにコマンドを実行しない。

## Functions

## depending packages

dependencies() {
    local list=""
    [ ! -f "$(which unbuffer)" ] && list="$list\"expect\" "
    [ "$list" != "" ] && echo -e "Please install next packages \n$list" 1>&2
}
