Hi,

In the test manual for the 'test' command, it states that:
"INTEGER may also be -l STRING, which evaluates to the length of 
STRING"
and even in the info page it gives an example of:

test -l abc -gt 1 && echo yes

but that command, as well as any in scripts, reports an error of:

bash: test: -l: unary operator expected

This has been the case since as far back as least the summer of 
2009 when after I shortly started using a Linux Operating System 
- that was PCLinuxOS back then, but now I am using openSUSE in 
the past year (currently version 11.4 KDE).

Regards,
Clifton

Note that it isn't standard.  It is a coreutils extension.

The error line tells all.  It says "bash: test" and that is the bash
test and not the coreutils test.

  $ type test
  test is a shell builtin

To get the coreutils test you would need to force it to be an external
command.

  $ /usr/bin/test -l abc -gt 1 && echo yes
  yes

Bob
