前言
在远程连接到linux进行操作时，经常要切换目录，有些目录切换频次较高，因此写了个shell工具，用于收藏目录、切换目录等。也不需要安装，直接添加脚本即可。
配置
首先声明脚本是基于bash shell，zsh和fish未经测试。
- 编辑文件
~/.bash_custom_functions，添加以下内容
mark(){ local markfile="$HOME/.mark" if [ ! -f ${markfile} ]; then echo "${markfile} is not exist, create it." touch ${markfile} fi case $1 in l) cat -n ${markfile} ;; d) # delete if [ "x" == "x$2" ]; then echo "need a sequence number" return 1 fi if [ $2 -lt 0 ] || [ $2 -gt $(wc -l < ${markfile}) ]; then echo "invalid sequence number" return 1 fi sed -i "$2d" ${markfile} ;; a) # add / append local new_mark=$(pwd) local tmp_grep=$(grep ${new_mark} ${markfile}) if [ "x" == "x${tmp_grep}" ]; then echo "mark current dirname: ${new_mark}" echo ${new_mark} >> ${markfile} else echo "Warning! Duplicate mark" fi ;; c) # cd if [ "x" == "x$2" ]; then echo "need a sequence number" return 1 fi if [ $2 -lt 0 ] || [ $2 -gt $(wc -l < ${markfile}) ]; then echo "invalid sequence number" return 1 fi local target_dir=$(sed -n "$2p" ${markfile}) if [ ! -d ${target_dir} ]; then echo "${target_dir} not found" return 1 fi cd ${target_dir} ;; *) echo "Options: l(ist), a(dd), d(elete), c(hange)" esac }
- 在
~/.bashrc中追加以下内容以引入上一步的文件
if [ -f ~/.bash_custom_functions ]; then . ~/.bash_custom_functions fi
- source生效，或者重建shell会话
source ~/.bashrc
