true

return true value (POSIX)

Syntax:

true

Description:

The true utility does nothing but exit immediately with a zero exit code.

The true utility is typically used in shell scripts. One common application is to create an infinite loop, as in:

   while true
   do
       myprogram
       sleep 300
   done

which runs myprogram every five minutes (300 seconds) until the shell script is interrupted.

Exit status:

The true utility always exits with a value of zero.
