Error description
ksh built-in æexitÆ command fails to exit shell during piping output into while loop in which calls a function that opens a specified file (. file) and then the æexitÆ command exists in it.
Local fix
Replaces piping output as redirecting input into while loop $ cat file last pipe output $ cat exit.sh #!/usr/bin/ksh exit $ cat test.sh #!/bin/ksh func() { . ./exit.sh echo "executing in func" } while read line < ./file do func echo "executing in main" done echo "exiting from main"
Problem summary
ksh built-in exit command may fail to exit shell when in a script we are piping an output into while loop, inside the while loop a function call is made, this functions sources a file/script using "." operator. In this file/script exit command is used. When all the above conditions are full filled then the built-in exit command may fail.
Problem conclusion
Code changes are made in ksh, to ensure that built-in exit works properly with the pipe operator, even when exit is called indirectly from a source file, being sourced inside a function.
Temporary fix
