Bash 交互式脚本

是否可以在第一个提示中提供多个要执行的变量？在第一个提示中，我想提供 1 个或 2 个（最多 5 个）在一个会话中执行特定脚本的变量。

例如：

echo -n "Enter the script you want to launch and press [ENTER]
read script

相反$script，我希望有一些替代方法，例如读取脚本 1 或脚本 2 ... 直到脚本 5，这使我能够使用这个单个条目启动任意数量的脚本 #i 想要的，并以任意组合（例如 1 和 2、1 和 3 和 5 等）

echo "Hello, "$USER".  This script will allow you to start $
echo "1. Claymore ZEC v12.6"
echo "2. Claymore ETH & SIA v10"
echo "3. Claymore ETH  v10"
echo "4. XMRIG ETN v2.4.4 //etn-pool.proxpool"
echo "5. XMRIG ETN v2.4.4 //pool.etn.spacepools.org"
echo "6. Quit"
echo -n "Enter the script you want to launch and press [ENT$
read script
case $script in
1) 
  echo "Starting to mine ZEC."
  cd ~/Downloads/claymore.s.Zcash.v12.6/;
  ./mine.sh;
  ;;
2)
  echo "Starting to mine ETH & SIA."
  cd ~/Downloads/claymore.dualminer.v10_ETHSIA/;
  ./mine.sh;
  ;;
3)
  echo "Starting to mine ETH."
  cd ~/Downloads/claymore.dualminer.v10_ETHSIA/;
  ./mineETH.sh;
  ;;
4)
  echo "Starting to mine ETN."
  cd ~/Downloads/Electroneum/XMRIG/build/;
  sudo sysctl -w vm.nr_hugepages=128;
  clear;
  cat /proc/meminfo | grep Huge;
  ./mine.sh;
  ;;
5)
  echo "Starting to mine ETN."
  cd ~/Downloads/Electroneum/XMRIG/build/;
  sudo sysctl -w vm.nr_hugepages=128;
  clear;
  cat /proc/meminfo | grep Huge;
  ./mine_space.sh;
  ;;
6) 
  echo "Quit"
  ;;
esac

我根据 @steeldriver 留下的评论为您整理了一个。这只是一个命令行脚本，允许在命令行上输入多个内容。它用于getopts多个选项，并添加了nohup command &将脚本移至后台以便运行下一个案例的功能。

如需进一步帮助，请在互联网上搜索 bash getopts。有很多东西需要学习，您可以编写出色的脚本来做任何您想做的事情。

剧本：

#!/bin/bash

#Set name
NAME=$(basename $0)

#Set option choices
OPTS="h12345"
PUSAGE=""

#This is how to use the script
usage="
Hello, "$USER".  This script will allow you to start the following. 
You can run as many as you like starting with a `-`.  Example below.

Usage:  ${NAME} [OPTIONS]

Options are:
  -h  Show this message.
  -1. Claymore ZEC v12.6
  -2. Claymore ETH & SIA v10
  -3. Claymore ETH  v10
  -4. XMRIG ETN v2.4.4 //etn-pool.proxpool
  -5. XMRIG ETN v2.4.4 //pool.etn.spacepools.org

Example:

${NAME} -135
"

#Run script
while getopts :${OPTS} i ; do
    case $i in
    1) 
      echo "Starting to mine ZEC."
      cd ~/Downloads/claymore.s.Zcash.v12.6/
      nohup ./mine.sh & 2>&1>/dev/null;;
    2)
      echo "Starting to mine ETH & SIA."
      cd ~/Downloads/claymore.dualminer.v10_ETHSIA/
      nohup ./mine.sh & 2>&1>/dev/null;;
    3)
      echo "Starting to mine ETH."
      cd ~/Downloads/claymore.dualminer.v10_ETHSIA/
      nohup ./mineETH.sh & 2>&1>/dev/null;;
    4)
      echo "Starting to mine ETN."
      cd ~/Downloads/Electroneum/XMRIG/build/
      sudo sysctl -w vm.nr_hugepages=128
      clear
      cat /proc/meminfo | grep Huge
      nohup ./mine.sh & 2>&1>/dev/null;;
    5)
      echo "Starting to mine ETN."
      cd ~/Downloads/Electroneum/XMRIG/build/
      sudo sysctl -w vm.nr_hugepages=128
      clear
      cat /proc/meminfo | grep Huge
      nohup ./mine_space.sh & 2>&1>/dev/null;;
    h | \?) PUSAGE=1;;
    esac
done

#Show help based on selection
if [ ${PUSAGE} ]; then
    echo "${usage}"
    exit 0
fi

#Check for input if none show help.
if [[ $1 == "" ]]; then
    echo "${usage}"
    exit 0
fi

现在，如果您运行该脚本，后面不加任何内容或不加任何-h帮助，则会出现以下内容。我命名我的脚本askhelp.bsh只是为了举例。

~$ ./askhelp.bsh

Hello, terrance.  This script will allow you to start the following. 
You can run as many as you like separated by spaces and dashes. Example below.

Usage:  askhelp.bsh [OPTIONS]

Options are:
  -h  Show this message.
  -1. Claymore ZEC v12.6
  -2. Claymore ETH & SIA v10
  -3. Claymore ETH  v10
  -4. XMRIG ETN v2.4.4 //etn-pool.proxpool
  -5. XMRIG ETN v2.4.4 //pool.etn.spacepools.org

Example:

askhelp.bsh -135

然后在我的测试脚本中我使其回显这些行以表明它们正在运行。

例子：

~$ ./askhelp.bsh -135
Starting Option 1
Starting to mine ZEC.
cd ~/Downloads/claymore.s.Zcash.v12.6/
nohup ./mine.sh & 2>&1>/dev/null
Starting Option 3
Starting to mine ETH.
cd ~/Downloads/claymore.dualminer.v10_ETHSIA/
nohup ./mineETH.sh & 2>&1>/dev/null
Starting Option 5
Starting to mine ETN.
cd ~/Downloads/Electroneum/XMRIG/build/
sudo sysctl -w vm.nr_hugepages=128
clear
cat /proc/meminfo | grep Huge
nohup ./mine_space.sh & 2>&1>/dev/null

另一个例子：

~$ ./askhelp.bsh -24
Starting Option 2
Starting to mine ETH & SIA.
cd ~/Downloads/claymore.dualminer.v10_ETHSIA/
nohup ./mine.sh & 2>&1>/dev/null
Starting Option 4
Starting to mine ETN.
cd ~/Downloads/Electroneum/XMRIG/build/
sudo sysctl -w vm.nr_hugepages=128
clear
cat /proc/meminfo | grep Huge
nohup ./mine.sh & 2>&1>/dev/null

根据请求的新脚本：

此脚本应gnome-terminal为每个回溯选择打开一个新终端。命令已为 完成gnome-terminal。如果您决定使用不同的终端，请确保对每个 case 语句中的命令进行适当的更改。

#!/bin/bash

#Set name
NAME=$(basename $0)

#Set option choices
OPTS="h12345"
PUSAGE=""

#This is how to use the script
usage="
Hello, "$USER".  This script will allow you to start the following. 
You can run as many as you like starting with a `-`.  Example below.

Usage:  ${NAME} [OPTIONS]

Options are:
  -h  Show this message.
  -1. Claymore ZEC v12.6
  -2. Claymore ETH & SIA v10
  -3. Claymore ETH  v10
  -4. XMRIG ETN v2.4.4 //etn-pool.proxpool
  -5. XMRIG ETN v2.4.4 //pool.etn.spacepools.org

Example:

${NAME} -135
"

#Run script
while getopts :${OPTS} i ; do
    case $i in
    1) 
      gnome-terminal -x bash -c 'echo "Starting to mine ZEC."; cd ~/Downloads/claymore.s.Zcash.v12.6/; ./mine.sh';;
    2)
      gnome-terminal -x bash -c 'echo "Starting to mine ETH & SIA."; cd ~/Downloads/claymore.dualminer.v10_ETHSIA/; ./mine.sh';;
    3)
      gnome-terminal -x bash -c 'echo "Starting to mine ETH."; cd ~/Downloads/claymore.dualminer.v10_ETHSIA/; ./mineETH.sh';;
    4)
      gnome-terminal -x bash -c 'echo "Starting to mine ETN."; cd ~/Downloads/Electroneum/XMRIG/build/; sudo sysctl -w vm.nr_hugepages=128; clear; cat /proc/meminfo | grep Huge; ./mine.sh';;
    5)
      gnome-terminal -x bash -c 'echo "Starting to mine ETN."; cd ~/Downloads/Electroneum/XMRIG/build/; sudo sysctl -w vm.nr_hugepages=128; clear; cat /proc/meminfo | grep Huge; ./mine_space.sh';;
    h | \?) PUSAGE=1;;
    esac
done

#Show help based on selection
if [ ${PUSAGE} ]; then
    echo "${usage}"
    exit 0
fi

#Check for input if none show help.
if [[ $1 == "" ]]; then
    echo "${usage}"
    exit 0
fi

希望这可以帮助！

您可以使用bash read命令从用户那里获取几个参数。

下面的例子取自bash 输入教程

下面的脚本在一个read命令中读取 3 个输入参数，并在脚本的后面使用这 3 个唯一参数。

cars.sh 脚本

#!/bin/bash
# Demonstrate how read actually works
echo What cars do you like?
read car1 car2 car3
echo Your first car was: $car1
echo Your second car was: $car2
echo Your third car was: $car3

终端执行：

./cars.sh
What cars do you like?
Jaguar Maserati Bentley
Your first car was: Jaguar
Your second car was: Maserati
Your third car was: Bentley
./cars.sh
What cars do you like?
Jaguar Maserati Bentley Lotus
Your first car was: Jaguar
Your second car was: Maserati
Your third car was: Bentley Lotus
