Thanks for the report.  However, this is not a bug in dirname, but in
your usage pattern.  You are invoking "dirname -bash", which dirname
(rightly) interprets as the attempt to be the -b option, but dirname
does not have a -b option.  You need to use -- to mark the end of
options and the start of arguments:

dirname -- "$0"

Wow, that's old.  The latest stable version is 8.10.

Wow, that's even older, but same story.

Hi, 

 

I execute the following bash command on RH 5.3 

CURRENT_DIR=`/usr/bin/dirname $0`

/usr/bin/dirname: invalid option -- b

Try `/usr/bin/dirname --help' for more information.

[oracle <at> mpawls ~]$ /usr/bin/dirname --version

$ echo $0

-bash

$ dirname

dirname: missing operand

Try `dirname --help' for more information.

$ dirname -b

dirname: invalid option -- b

Try `dirname --help' for more information.

 

I tried it also on Centos 5.5 with same result.

 

Instead on RH 4.x------------------------------------------

$ CURRENT_DIR=`/usr/bin/dirname $0`

$ /usr/bin/dirname --version
