The ksh can tell you version if you have command line editing (set -o vi or emacs) by typing escape + ctrl-V. Some systems have an enhanced ksh93 as dtksh (in the CDE package) or the like, even if they do not have ksh updated to ksh93.

Yes, recall the joys of SQL Injection attacks on web services. Know your inputs before you turn them into executables, like with eval or '... | bash'. Think worst case, like embedded '&', ';', '$', '"', "'", carriage returns, page feeds. line feeds, . . . .

shift
shift(1) User Commands shift(1)
NAME
shift - shell built-in function to traverse either a shell's argument list or a list of field-separated words
SYNOPSIS
sh
shift [n]
csh
shift [variable]
ksh
*shift [n]
ksh
+shift [n]
DESCRIPTION
sh
The positional parameters from $n+1 ... are renamed $1 ... . If n is not specified, it is assumed to be 1.
csh
The components of argv, or variable, if supplied, are shifted to the left, discarding the first component. It is an error for the variable
not to be set or to have a null value.
ksh
The positional parameters from $n+1 $n+1 ... are renamed $1 ..., default n is 1. The parameter n can be any arithmetic expression that
evaluates to a non-negative number less than or equal to $#.
On this manual 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, following a command preceded by ** that are in the format of a variable assignment, are expanded with the same rules as a
variable assignment. This means that tilde substitution is performed after the = sign and word splitting and file name genera-
tion are not performed.
ksh93
shift is a shell special built-in that shifts the positional parameters to the left by the number of places defined by n, or 1 if n is
omitted. The number of positional parameters remaining is reduced by the number of places that are shifted.
If n is specified, it is evaluated as an arithmetic expression to determine the number of places to shift. It is an error to shift more
than the number of positional parameters or a negative number of places.
The following exit values are returned by shift in ksh93:
0 Successful completion. The positional parameters were successfully shifted.
>0 An error occurred.
On this manual page, ksh93(1) commands that are preceded by one or two + 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. They are not valid function names.
5. Words, following a command preceded by ++ that are in the format of a variable assignment, are expanded with the same rules as a
variable assignment. This means that tilde substitution is performed after the = sign and field splitting and file name genera-
tion are not performed.
