multiple shell command interpreter on script....

[John Joaquin]

guys,

I'm planning to create a large shell script but it require multiple language/module such as expect & perl within the ksh... Should i put any extra expression on the header of my script....

No, you can only have one she-bang at the top of the script.

Your best bet would be to call other scripts from within the main script.

For example:

# cat mainscript.sh
#!/usr/bin/sh

...Do some stuff...
/dir/script.expect
...Do some other stuff...
/dir/script1.perl
...Do some more stuff...

# cat script.expect
#!/path/to/expect
Do some expect stuff......

# cat script1.perl
#!/path/to/perl
Do some perl stuff.....
