1.创建安装脚本

cd /usr/localvim gotopDownload.sh

#!/usr/bin/env bash# https://gist.github.com/lukechilds/a83e1d7127b78fef38c2914c4ececc3c
function get_latest_release {curl --silent "https://api.github.com/repos/$1/releases/latest" | # Get latest release from GitHub apigrep '"tag_name":' |                                          # Get tag linesed -E 's/.*"([^"]+)".*/\1/'                                  # Pluck JSON value
}function download {RELEASE=$(get_latest_release 'cjbassi/gotop')ARCHIVE=gotop_${RELEASE}_${1}.tgzcurl -LO https://github.com/cjbassi/gotop/releases/download/${RELEASE}/${ARCHIVE}tar xf ${ARCHIVE}rm ${ARCHIVE}
}function main {ARCH=$(uname -sm)case "${ARCH}" in# order mattersDarwin\ *64)        download darwin_amd64   ;;Darwin\ *86)        download darwin_386     ;;Linux\ armv5*)      download linux_arm5     ;;Linux\ armv6*)      download linux_arm6     ;;Linux\ armv7*)      download linux_arm7     ;;Linux\ armv8*)      download linux_arm8     ;;Linux\ aarch64*)    download linux_arm8     ;;Linux\ *64)         download linux_amd64    ;;Linux\ *86)         download linux_386      ;;*)echo "\No binary found for your system.Feel free to request that we prebuild one that works on your system."exit 1;;esac
}main

2. 赋予脚本执行权限

chmod +x gotopDownload.sh

 3.执行脚本，根据你当前的操作系统自动下载二进制文件gotop程序到当前目录下

./gotopDownload.sh 

4.添加到系统命令

cp gotop /usr/local/bin

5.执行gotop命令进行查看

gotop
