Solaris

Hmm filename seems to be missing.
What's the equivalent output from:

Code:

ls -lisa
ls -lisab
ls -lisa|sed -n l

Posted one above the other so we can see if the columns line up.

I suppose you could have a filename consisting of one or more space characters or control codes.

Is it a local directory or NFS mounted?

The filename is SystemOut_12.03.13_15.00.42.log

It's a local directory

What is the output of:

Code:

ls -ld directory
ls -l directory/SystemOut_12.03.13_15.00.42.log

Can you cd to the directory?

Yes i can cd to the directory and manipulate the others file on that directory. Only this file who has problem

In addition to the directory listings requested above, what is the output from:

Code:

fuser SystemOut_12.03.13_15.00.42.log

The directory listings are important if only to prove that the file has the name you think it has. Also it will tell us if the timestamp is changing because something is still writing to the file.
Also, when you get a command which does not work, do you get an error message or is it a problem with what the command did?

You are right. There is a process still writing on this file. But i used to manipulate the file even if it was used by that process.
