[linux]mark-tool

简介: [linux]mark-tool

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。

  1. 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
}
  1. ~/.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
  1. source生效,或者重建shell会话
source ~/.bashrc
