Top Forums UNIX for Beginners Questions & Answers How to write a Boolean variable which succeed and failed inside the if loop in shell script ? Post 303040728 by Scrutinizer on Tuesday 5th of November 2019 04:10:01 PM
This will only check if one of the conditions is true, but not which one is true. If you want to find out, which of the expression is true, you will need to check them one by one..

Which means something like this:
Code:
if (( dm > 0 || cl == 100 || ad == 0 || me > 8 || cp > 0 )); then
  if (( dm > 0 )); then
    echo "dm > 0 "
  fi
  if (( cl == 100 )); then
    echo "cl == 100 "
  fi
   if (( ad == 0 )); then
    echo "ad == 100"
  fi
  if (( me > 8 )); then
    echo "me > 8 "
  fi
  if (( cp > 0 )); then
    echo "cp > 0 "
  fi
else
  echo "None of the conditions are true"
fi

For a shorthand way, you could try something like this:
Code:
if (( dm > 0 || cl == 100 || ad == 0 || me > 8 || cp > 0 )); then
  (( dm > 0 ))    && echo "dm > 0 "
  (( cl == 100 )) && echo "cl == 100 "
  (( ad == 0 ))   && echo "ad == 100"
  (( me > 8 ))    && echo "me > 8 "
  (( cp > 0 ))    && echo "cp > 0 "
else
  echo "None of the conditions are true"
fi

Generally speaking, Unix systems are commercial, closed source and propriety operating systems so it is expensive to customize for supercomputing projects. Linux, on the other hand, is free and easier to customize.

NAME
break, continue - shell built-in functions to escape from or advance within a controlling while, for, foreach, or until loop SYNOPSIS
sh break [n] continue [n] csh break continue ksh *break [n] *continue [n] DESCRIPTION
sh The break utility exits from the enclosing for or while loop, if any. If n is specified, break n levels. The continue utility resumes the next iteration of the enclosing for or while loop. If n is specified, resume at the n-th enclosing loop. csh The break utility resumes execution after the end of the nearest enclosing foreach or while loop. The remaining commands on the current line are executed. This allows multilevel breaks to be written as a list of break commands, all on one line. The continue utility continues execution of the next iteration of the nearest enclosing while or foreach loop. ksh The break utility exits from the enclosed for, while, until, or select loop, if any. If n is specified, then break n levels. If n is greater than the number of enclosing loops, the outermost enclosing loop shall be exited. The continue utility resumes the next iteration of the enclosed for, while, until, or select loop. If n is specified then resume at the n- th enclosed loop. If n is greater than the number of enclosing loops, the outermost enclosing loop shall be used. On this man page, ksh(1) commands that are preceded by one or two * (asterisks) are treated specially in the following ways: 1. Variable assignment lists preceding the command remain in effect when the command completes. 2. I/O redirections are processed after variable assignments. 3. Errors cause a script that contains them to abort. 4. Words that follow a command preceded by ** that are in the format of a variable assignment are expanded with the same rules as a vari- able assignment. This means that tilde substitution is performed after the = sign, and also that word splitting and file name genera- tion are not performed. ATTRIBUTES
