Hi,

 

I get the following error .

 

basename: invalid option -- b
Try `basename --help' for more information.
basename: missing operand

 

I have basename used as

 

CMDE=`\basename $0 .sh`
echo "$basename is $CMDE"

 

Doesn't o/p anything. Please

Regards,

Syed

Thanks for the report.  However, this is not a bug in basename, but in
your usage.

That's your problem.  $0 expanded to "-bash", so basename is trying to
parse -b as an option.  Instead, use:

basename -- "$0" .sh

to avoid issues with $0 having a leading '-'.  If you want to do more
