can anyone explain what is going on here?

So I go looking at my printer configuration:

Code:

prompt$  ls -lh /etc/cups/ppd/O*



-rw-r--r-- 1 root root 2.6K 2012-01-26 16:03 /etc/cups/ppd/OJet6500_fax.ppd

-rw-r--r-- 1 root root  23K 2012-01-26 16:03 /etc/cups/ppd/OJet6500_prt.ppd

-rw-r--r-- 1 root root 2.8K 2012-08-05 22:09 /etc/cups/ppd/Ojet7300_fax.ppd

-rw-r--r-- 1 root root  24K 2012-08-05 22:09 /etc/cups/ppd/OJet7300_prt.ppd

I wonder about the details for one of the printers:

Code:

prompt $ less /etc/cups/ppd/Ojet7300_prt.ppd 



/etc/cups/ppd/Ojet7300_prt.ppd: No such file or directory

On further inspection I get:

Code:

prompt $ stat /etc/cups/ppd/Ojet7300_prt.ppd 



stat: cannot stat `/etc/cups/ppd/Ojet7300_prt.ppd': No such file or directory



prompt $ fuser /etc/cups/ppd/Ojet7300_prt.ppd 



Cannot stat /etc/cups/ppd/Ojet7300_prt.ppd: Bad address

I've never seen a file that exists but yet does not exist.

Can anyone explain what is going on?
Can anyone offer steps for more diagnosis?

Stumped,

longshot.....

the filename has one or more spaces on the end..

spam your tab key and see if comandline completion. helps out

So I try:

Code:

prompt$  stat /etc/cups/ppd/{TAB}



OJet6500_fax.ppd  ojet7300_fax.ppd  ojet7300_prt.ppd  

OJet6500_prt.ppd  Ojet7300_fax.ppd  OJet7300_prt.ppd

Then I try:

Code:

prompt$ stat /etc/cups/ppd/OJet{TAB}



OJet6500_fax.ppd  OJet6500_prt.ppd  OJet7300_prt.ppd

Lastly, I try:

Code:

prompt$ stat /etc/cups/ppd/OJ{TAB}

... and I get ...

prompt$ stat /etc/cups/ppd/OJet7

... and again ...

prompt$ stat /etc/cups/ppd/OJet7{TAB}

... and I get ...

prompt$ stat /etc/cups/ppd/OJet7300_prt.ppd 



  File: `/etc/cups/ppd/OJet7300_prt.ppd'

Change: 2012-08-05 22:09:58.385534094 -0500

The trouble was the mixed use of upper and lower case letters in the file names.
Looking at the original list of files:

there is an all lower case "ojet" 7300
there is a cap-O, cap-J "OJet" 7300 prt but not fax
there is a cap-O, low-j "Ojet" 7300 fax but not prt

My commands did, in fact, ask for files that did not exist.
