bash实现当前路径下子目录跳转

说明

很早之前尝试过autojump项目，当时使用bash函数实现jc功能，最低测试过Ubuntu16.04
日常中高频使用，今天使用添加了bash补全，分享给诸位

配置

function _j_completion() {
    local cur=${COMP_WORDS[COMP_CWORD]}
	COMPREPLY=($(compgen -W "$(echo -n $PWD | sed 's/\// /g')" -- $cur))
}
function j() {
	local path=${PWD%$1*}
	local dir=${PWD:${#path}}
	cd ${path}${dir%%/*}
}
complete -o nospace -F _j_completion j

效果
