need to return value from function

Shell Programming and Scripting

how to return value from function and print from main program???
And also I need to return true or false... Is it possible?

Sure you can do both, just like from any shell script. Output is output and exit / return status is a different thing.

myfunc () {
  echo Fnord
  return 42
}

It's certainly possible, which is the language in use ?

If it's used in sub routine, use "return" function, otherwise printing the last value can be done with 'print "$variable_name\n"'
Also, you can always define custom return codes and strings, and print them when matching certain conditions.
