#!/bin/bash - function mytest() { echo "arg1 = $1" if [ $1 = "1" ] ;then return 1 else return 0 fi } if mytest 2; then echo "aaaaaaaaaa" fi
执行结果:
稍微改一下
#!/bin/bash -
function mytest()
{
echo "arg1 = $1"
if [ $1 = "1" ] ;then
return 1
else
return 0
fi
}
if mytest 1; then
echo "aaaaaaaaaa"
fi

shell 中定义的变量是全局的,函数上面定义的变量在函数内部仍然是可见的
#!/bin/bash - g_var= function mytest2() { echo "mytest2" echo "args $1" g_var=$1 return 0 } mytest2 1 echo "return $?" echo echo "g_var=$g_var"
