如何从bash脚本运行shell脚本

我在运行以下命令时出现错误（在：sh up.sh行上）：

#!/bin/bash

# Install angular components 
echo "Installing Angular Components..."
cd angApp
npm install

# Install Server components
echo "Installing Backend Components..."
cd ..
cd APIServer

# go back to main dir
cd ..

# ask to see if we should launch server
echo "Do you want to launch the server now? Enter (yes/no)  "
read shouldLaunch

# Launch if requested. Otherwise end build
if [ "$shouldLaunch" == "yes" ]; then
    echo "Great! Launching the servers for you..."
    sh up.sh
else
    echo "No problem..."
    echo "you can launch the server by doing ./up.sh"
    echo "bye!"
fi

如何运行up.sh脚本？

如果

up.sh

文件与包含上述代码的文件位于同一目录中，则可以执行以下操作

echo "Great! Launching the servers for you..."
$(dirname $0)/up.sh

---

变量

$0

是当前脚本的路径，

dirname

去掉路径的最后一段，

$（…）

将

dirname

的输出转换为字符串。

如果

up.sh

文件与包含上述代码的文件位于同一目录中，则可以执行此操作

echo "Great! Launching the servers for you..."
$(dirname $0)/up.sh

为了避免

cd

-ing混乱，只需在子shell中运行部分，如：

#!/bin/bash

(
# Install angular components - in shubshell
echo "Installing Angular Components..."
cd angApp
npm install
)

(
# Install Server components - again in subshell
echo "Installing Backend Components..."
cd APIServer
#do something here
)    

# go back to main dir
#cd .. #not needed, you're now in the parent shell...

# ask to see if we should launch server
echo "Do you want to launch the server now? Enter (yes/no)  "
read shouldLaunch

# Launch if requested. Otherwise end build
if [ "$shouldLaunch" == "yes" ]; then
    echo "Great! Launching the servers for you..."
    sh up.sh
else
    echo "No problem..."
    echo "you can launch the server by doing ./up.sh"
    echo "bye!"
fi
