Actually there can be an impact on disk space. If you have regular files in /proc/pid/fd with link count 0, then this process has a file open, which is not visible in the file system, but consumes disk space. The disk space used will be freed once the process ends or closes the file.
Example:
This file (named dummyfile before it was deleted) still uses 12MB on disk until the sleep command running in the background ends or is killed.
if I have 1000 files, named file1, file2, ... ,file1000. for each one, I want to append a line, for example "this is the end of file#".
then, I want to link them all together.
how can I do that by using a simple script? (1 Reply)
Hi,
I need to write a shell script that should lists only the files that starts with alphabet from the /proc dir and then I have to cat those files and redirect to a file.
But my below script is not working. It is reading the first file properly but not the subsequent files. Please throw a... (2 Replies)
Hi All,
Please explain me the concept of link counts when you try to view the contents of any file or directory using ls command.
-sh-3.00$ ls -lrt

Hi,
I am trying to calculate the CPU Usage by getting the difference between the idle time reported by /proc/stat at 2 different intervals. Now the 4th entry in the first line of /proc/stat will give me the 'idle time'. But I also came across /proc/uptime that gives me 2 entries : 1st one as the... (0 Replies)

Currently my data is organised in a volume which has a cache directory (where all the files are first created or transferred). After that there are suitable directories on the volume which in their subdirs, contain files hardlinked to files in the cache. This is done so that the same inode... (1 Reply)
I run a find command to search from root directory.

Hi Experts,
I had encountered an issue where the zero link process was holding too much amount of data on a Solaris server. I was able to terminate the process after which the space of the file system was released.

lsdev
LSDEV(8) Linux System Manual LSDEV(8)NAME
lsdev - display information about installed hardware
SYNOPSIS
lsdev
DESCRIPTION
lsdev gathers information about your computer's installed hardware from the interrupts, ioports and dma files in the /proc directory, thus
giving you a quick overview of which hardware uses what I/O addresses and what IRQ and DMA channels.
OPTIONS
None.
FILES
/proc/interrupts
IRQ channels.
/proc/ioports
I/O memory addresses.
/proc/dma
DMA channels.
BUGS
lsdev can't always figure out which lines in the three examined files refer to one and the same device, because these files sometimes use
different names for the same piece of hardware. For example, in some kernels the keyboard is referred to as `kbd' in /proc/ioports and as
`keyboard' in /proc/interrupts. This should be fixed in the kernel, not in lsdev (as has indeed happened for this particular example).
The program does however try to match lines by stripping anything after a space or open parenthesis from the name, so that e.g. the
`serial' lines from /proc/interrupts match the `serial(set)' lines from /proc/ioports. This attempt at DWIM might be considered a bug in
itself.
This program only shows the kernel's idea of what hardware is present, not what's actually physically available.
