You have $LINENO, but it restarts counting from 1 in functions. But if
you invoke the function with $LINENO as argument, the calling line
number will be substituted and passed to the function.

$ cat -n lineno_test.sh
  1  #!/bin/bash
  2
  3  function myfn()
  4  {
  5    echo "this function has been called from line number #$1"
  6  }
  7
  8  myfn $LINENO
  9
 10  exit 0

$ ./lineno_test.sh
this function has been called from line number #8
$
