Bash交互脚本

Question

是否可以在第一个提示符中提供多个要执行的变量？在开始提示时，我想提供最多5个变量，这些变量在一个会话中执行特定的脚本。

例如：

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

而不是$script，我想有一些选择，比如阅读script1或script2 .直到script5，它允许我在任何组合(例如1和2、1和3、5等)下用这个单一条目执行任意数量的脚本#。

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

Answer 1

根据@steeldriver留下的评论，我为你拼凑了一个。这只是一个命令行脚本，允许在命令行上进行多个输入。它将getopts用于多个选项，并添加nohup command &以将脚本移动到后台，以便下一种情况能够运行。

要获得更多帮助，请在互联网上搜索bash getopts。有那么多东西需要学习，你可以制作出令人难以置信的脚本来做你想做的任何事情。

The脚本：

#!/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，如果您在运行脚本时没有使用“后”或“-h”作为帮助，则会出现以下内容。我把我的脚本askhelp.bsh命名为一个例子。

~$ ./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，我制作了它，这样它就可以回显这些行，以显示它们正在运行。

示例：

~$ ./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

另一个例子是：

~$ ./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

请求中的New脚本：

这个脚本应该为每个用于跟踪的选择打开一个新的gnome-terminal。这些命令是为gnome-terminal完成的。如果您决定使用不同的终端，请确保在每个case语句中对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

希望这能有所帮助！

您可以使用bash read命令从用户获得多个参数。

下面的示例取自巴什输入教程

下面的脚本在一个read命令中读取3个输入参数，并在脚本后面使用这3个唯一的参数。

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

Terminal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
