ls file exist, but can't access.

09-26-2012, 04:33 PM

$ ls -lrt
total 8
-rw-r--r-- 1 lina lina 367 Sep 27 00:15 RET
drwx------ 2 lina lina 4096 Sep 27 00:16 auto-save-list

$ ls -lrt RET
ls: cannot access RET: No such file or directory

$ cat RET
cat: RET: No such file or directory

$ rm RET
rm: cannot remove `RET': No such file or directory

:~/.emacs.d$ ls
auto-save-list RET

Is it weird? or this file stored in some weird place.

There is another thing, which is isolated from this one,

Filesystem Size Used Avail Use% Mounted on
/dev/sda1 95G 54G 37G 60% /
/dev/sda3 1.2T 681G 482G 59% /data
tmpfs 12G 1012K 12G 1% /dev/shm
apricot2-local:/vol/ds_vol
4.6T 1.9T 2.8T 40% /home
/dev/gpfs1 5.5T 919G 4.6T 17% /gpfs_data

/dev/gpfs1 is twice faster than /home/lina checked via dd in read and
write speed, but `ls` so slow.

I don't know how to check, indeed I have thousands of files generated
there. so I could obviously feel the time retard.

Thanks for your time,

Best regards,

It looks like the file is not named "RET" bus " RET" instead. Quote the
whitespace and you should be able to read/delete it.

Look closer: there's a space you are overlooking.

ls -ls " RET"

might work, and

ls -ls *RET

will definitely work (in case that character is not a space).

That's the main reason I always use a fixed-pitch font for CLI stuff and email.

So why was your post HTML?

Hoist on me own petard!

I thought I had all that turned off long ago. It keeps sneaking back, though.

If what you're posting is an exact capture, it looks like RET has some
sort of character before the R -- possibly a space? Try

ls " RET"

and see what happens.

I assume /ddv/gpfs1 is some sort of local device, while
aricot2-local:/vol/ds_vol is being accessed through NFS? If that's the
case, the latter is coming across a network which would make it
substantially slower (especially depending on what the network looks
like).
