shell script创建库

先创建名称为 myfuns

# my script functions

function addem {
  echo $[ $ + $ ]
}

function multem {
  echo $[ $ * $ ]
}

function divem {
  if [ $ -ne  ]
  then
    echo $[ $ / $ ]
  else
    echo -
  fi
}

然后创建脚本，名称为： test14.sh

#!/bin/bash
# using functions defined in a library file
./myfuns

value1=;
value2=
result1=`addem $value1 $value2`
result2=`multem $value1 $value2`
result3=`divem $value1 $value2`
echo "The result of adding them is: $result1"
echo "The result of multiplying th is: $result2"
echo "The result of dividing them is: $result3"

其中 ./myfuns 是调用该文件，具体使用时可能因路径不同而使用不同的路径，本文中两个文件放在同一目录下

运行  sh test14.sh

输出：

test14.sh: line : addem: command not found
test14.sh: line : multem: command not found
test14.sh: line : divem: command not found
The result of adding them is:
The result of multiplying th is:
The result of dividing them is:
