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
