Use ksh instead bash. You are probably used to ksh anyway when you come from AIX and it is available on every Linux since some time now. When using ksh you have the shell-internal "print" for output. It allows to explicitly end options by using a single dash:

Code:
print -u2 "foo bar"

will output "foo bar" to stderr (-u2) but:

Code:
print - -u2 "foo bar"

will write "-u2 foo bar" to stdout, because "-u2" is no longer considered an option.

Per default i use it that way, especially if i do not know what a variable i want to display contains:

Code:
print - "$var"

Even if "$var" contains options to "print" they will be ignored.

I hope this helps.
