Calling Function Problem

Hi,

I had a scripts which calls two function. One function will call another function, script is working fine but the second function is not calling the first function. Below is the script

Code:
#!/usr/bin/ksh
fun1() {
echo $DATETIME >> Test1.ksh
return 0
}
fun2() {
typeset DATETIME=`date +%Y%m%d' '%T`
fun1
return 0
}

When I run the above script in which I'm calling fun1 in fun2. But I'm not able to see any data in Test1.ksh and it is a zero size file. Help me in understanding why the DATETIME was not written to Test1.ksh file.


Thanks,
Raju

Because you never told it to.

Yes.

Code:
fun1() {
echo $DATETIME >> Test1.ksh
return 0
}
fun2() {
typeset DATETIME=`date +%Y%m%d' '%T`
fun1
return 0
}

fun2  # <-- call function fun2

Code:
# cat Test1.ksh

You need a line in the script that calls fun2. Add:

Code:
fun2
