stdout to file or character device with trailing slash
I have an interesting one for the gurus out there that may have an idea as to why this is happening. We're currently migrating from Solaris 9 to Solaris 10 and we've run into a very strange issue. There are a bunch of shell scripts people have written throughout a directory that are used for particular systems that have code in there that directs output to /dev/null/ (notice the trailing slash). I suspect this started from someone making the mistake and then copying it through other scripts. e.g.
Code:
echo "bla" > /dev/null/

I understand that this is wrong syntax however on Solaris 9, using all shells, it allows this to go through. Actually, I can put as many trailing slashes as I went (e.g. /dev/null////) and it will just ignore. On Solaris 10, however, it will error out with "Is not a directory". Also, on other Linux/UNIX distros it errors out with the same behavior.

I am probably just going to recursively replace these instances with proper formed code however I'm just wondering if someone has any thoughts on this.

NAME

       msglog - message output collection from system startup or background applications

NOTES

       In  the	current  version of Solaris, /dev/msglog is an alias for /dev/sysmsg.  In future versions of Solaris, writes to /dev/msglog may be
       directed into a	more general logging mechanism such as syslogd(1M).

       syslog(3C) provides a more general logging mechanism  than /dev/msglog and should be used in preference to /dev/msglog whenever possible.
