[bash] 编写7zz函数替换7z压缩命令

安装 p7zip 然后将下面内容放到 ~/.zshrc 或者 ~/.bashrc

function 7zz() {
    # compress a direcotry to directory.7z
    # usage: 7zz path/to/directory [7z options]
    # returns: 0 - successful, 1 - argument error, 2 - not found 7z command
    local ok=$(command -v 7z >/dev/null 2>/dev/null && echo 'ok' || echo '')
    if [ "$ok" != "ok" ]; then
        echo 'not found 7z command, please install p7zip'
        return 2
    fi

    local dir="$1"
    local target="$(basename ${dir%/}.7z)"
    if [ ! -d "$dir" ]; then
        echo 'argument error
usage: 7zz path/to/directory [7z options]'
        return 1
    fi
    if [ -f "$target" ]; then
        while true; do
            printf "Are you sure overwrite file "$target"? [y/N] "
            read yn
            case $yn in
            [yY][eE][sS] | [yY]) break ;;
            [nN][oO] | [nN] | "") return 0 ;;
            *) ;;
            esac
        done
        rm -f "$target"
    fi

    shift
    7z a -mx=9 -xr!.DS_Store "$@" "$target" "$dir"
}

然后打开新会话或者重新载入配置文件

source ~/.zshrc

或者

source ~/.bashrc

命令格式：

7zz 目录 [7z的参数]

例子1：压缩 abc 目录为 abc.7z

7zz abc

例子2: 压缩vscode的扩展目录，并且排除cocos扩展，重命名为vscode_extensions.7z

7zz ~/.vscode/extensions -xr!cocos-creator -xr!cocos-debug && mv {,vscode_}extensions.7z
