#!/bin/
bash
function
myfun()
{
echo
"
echo result
"
return
0
}
returnValue
=
$(myfun)
echo
"
${returnValue}
"
这里returnValue得到的并不是0,而是"echo result",想要得到function内的return 值, 要用$?
输出:
$ bash -x test.sh
++ myfun
++ echo 'echo result'
++ return 0
+ returnValue='echo result'
+ echo 'echo result'
echo result
得到返回值,应该像下面这么写
#!/bin/
bash
function
myfun()
{
echo
"
echo result
"
return
0
}
returnValue
=$?
echo
"
${returnValue}
"
输出
$ bash -x test.sh
+ returnValue=0
+ echo 0
0
