SYNOPSIS

eval [argument ...]

DESCRIPTION

The KornShell evaluates each argument as it would for any command. eval then concatenates the resulting strings, separated by spaces, and evaluates and executes this string in the current shell environment.

---

EXAMPLES

The command:

for a in 1 2 3
do
  eval x$a=fred
done

sets variables x1, x2 and x3 to fred. Once this has been done,

echo $x1 $x2 $x3

produces:

fred fred fred

---

DIAGNOSTICS

Possible exit status values are:

0

You specified no arguments or the specified arguments were empty strings.

Otherwise, the exit status of eval is the exit status of the command that eval executes.
