Shalom,

Install gpm the gui portion of glance.

gpm has a high water mark that can show use of files.

Or:

did you consider

lsof | wc -l

yet ?

you might need to use additional commands in the pipe to exclude some files or applications but this should give you a starting point.

{lsof=list open files as name implies)

Hope this helps

Hi ,

To know the number of open use this command.

#sar -v 2 2

HP-UX hpserver B.11.11 U 9000/800 05/06/09

15:10:58 text-sz ov proc-sz ov inod-sz ov file-sz ov
15:11:00 N/A N/A 300/4096 0 4164/8192 0 7897/32778 0
15:11:02 N/A N/A 300/4096 0 4164/8192 0 7897/32778 0

here it is 7897 out of it's maximum 32778(nfile value)

Thanks for all replies.

Is there any way to check which process has open which file.

Any way to track individual process has opened how many files ?

Thanks in advance.

That is just what lsof excels at! See the man page:
