You want to execute line to output the number of open files per process like this
Code:
4 yum
6 http
1 vim
.
.
Or like this
Code:
[root@router scripts]# ps aux | grep -i yum | wc -l
2
[root@router scripts]# ps aux | grep -i vim | wc -l
4
Wawoo, thanks, I didn't know that before & I'll definitely save these commands with me. I think that command ps aux | grep -i vim | wc -l will bring more cooler results.
Hi, I know this is a dumb question
I am trying to find the number of open files per process, and I found few commands but each gives deferrent values. below are the commands
ls /proc/<pid>/fd/*
and
lsof -p <PID>
Can some one tell me what I am doing wrong or am I reading the out put wrong
Thanks and Best Regards
I think its a valid question. I always used lsof whenever I was unable to unmount file system, so that I could see what files are still used by that file system. I never used /proc/<pid>/fd.
So it seems, both lsof and /proc/<pid>/fd bring different results for same pid.
I did little search in internet and it seems the difference between output from lsof and /proc/<pid>/fd/ are because lsof also displays other file descriptors and memory mapped .so files, which are mapped at /proc/<pid>/maps.
