Runing a function from Case Statement 3

[chris01010]

Hi,

I have the below script that should take the command line option and run the desired script on another server. Only it doesn't seem to run the function, infact it just returns back to the command line.

      case $1 in
           1) msgbacklog() ;;
           2) jobstatus() ;;
      esac

msgbacklog () 
{
ssh BLAH@SERVER1 > output 2>/dev/null  <<_EOF
/home/BLAH/backlog.ksh
_EOF
}

jobstatus () 
{
ssh BLAH@SERVER1 > output 2>/dev/null  <<_EOF
/home/BLAH/jobstatus.ksh
_EOF
}

Any ideas?

Hi

Two things :
[ol]
[li]You must define functions before calling them.[/li]
[li]You call functions without the parenthesis ( () ).[/li]

You must define functions before calling them
Really ?
In which sort of shell ?

[blue]master #[/blue] cat sh.sh 
case 1 in
1) foo ;;
esac

foo()
{
date
}

[blue]master #[/blue] bash sh.sh 
sh.sh: line 2: foo: command not found

[blue]master #[/blue] dash sh.sh 
sh.sh: 2: sh.sh: foo: not found

[blue]master #[/blue] mksh sh.sh 
sh.sh[3]: foo: not found

[blue]master #[/blue] zsh sh.sh 
sh.sh:2: command not found: foo

Vs.

[blue]master #[/blue] cat sh.sh 
foo()
{
date
}

case 1 in
1) foo ;;
esac

[blue]master #[/blue] dash sh.sh

[blue]master #[/blue] bash sh.sh 
Tue Dec  6 17:20:17 EET 2011

[blue]master #[/blue] mksh sh.sh 
Tue Dec  6 17:20:20 EET 2011

[blue]master #[/blue] zsh sh.sh 
Tue Dec  6 17:20:23 EET 2011

I would say, all Bourne shell compatible shells. Was my conclusion wrong ?

OOps, you're right.
Same beaviour with legacy bourne shell and korn shell.

Hope This Helps, PH.
