安装 FISH
要安装 fish，它需要 Python 软件属性，使用以下命令安装 python –
$ sudo apt-get install python-software-properties
示例输出应如下所示–
Reading package lists... Done Building dependency tree Reading state information... Done The following extra packages will be installed: python-pycurl Suggested packages: libcurl4-gnutls-dev python-pycurl-dbg The following NEW packages will be installed: python-pycurl python-software-properties 0 upgraded, 2 newly installed, 0 to remove and 7 not upgraded.

现在，我们应该调用 fish 存储库，如下所示-
$ sudo add-apt-repository ppa:fish-shell/nightly-master
输出应该是这样的 –

使用以下命令更新 Linux 软件包 –
$ sudo apt-get update
要安装 fish，请使用以下命令 –
$ sudo apt-get install fish
输出应如下所示 –
