Yes, of course. "SLES" is for "SuSE Linux Enterprise System" - basically SuSE with less options but with a high price so that big business can "buy" the good.

They have i.e. from SLES 11 to SLES 12 dropped the real ksh93 from their repository and now have some "pdksh" under the name of "ksh" (which you only find out if you are willing to follow a symlink pointing to a symlink pointing to a.... - and of course by seeing your ksh scripts fail) and they also dropped ext4 and ext2 and ext in favour of ext3 without announcement (try updating a system from SLES 11 to SLES 12 and half of your filesystems might be missing without notice) - but, hey, they are charging a lot of money for that, so it must be good, no?

Sorry for some traces of sarcasm in my diatribe its a leftover from applying "common sense" (actually not part of ITIL) to systems administration.

let

let(1)								   User Commands							    let(1)

NAME

       let - shell built-in function to evaluate one or more arithmetic expressions

SYNOPSIS

   ksh
       let arg...

   ksh93
       let [expr...]

DESCRIPTION

   ksh
       Each arg is a separate arithmetic expression to be evaluated.

   ksh93
       let  evaluates  each expr in the current shell environment as an arithmetic expression using ANSI C syntax. Variables names are shell vari-
       ables and they are recursively evaluated as arithmetic expressions to get numerical values. let has been made obsolete by the ((...))  syn-
       tax of ksh93(1) which does not require quoting of the operators to pass them as command arguments.

EXIT STATUS

   ksh
       ksh returns the following exit values:

       0    The value of the last expression is non-zero.

       1    The value of the last expression is zero.

   ksh93
       ksh93 returns the following exit values:

       0     The last expr evaluates to a non-zero value.

       >0    The last expr evaluates to 0 or an error occurred.
