Fuser command

[root@c83-250-88-242 ka]# fuser -a /home

/home:

What is the fuser comand? I looked at the man pages. It should see the user id, display unused files, kill processes accessing that file and search IPV4 sockets etc.

Could you tell me how to use it find some of the above?

It's more to do with the apps you are using. "lsof" will give a list of all files used by all applications, in the form:
[filename] [pid] [other.......stuff........]
From this you can infer pid's from files in use, fuser does a similar thing but you can find a process by socket too.... read the man page of both. twice.

The 'ls of' command gave me a big list of files. I will write some of them here.

What program are you looking for exactly? A handy addon is "grep" eg.

Code:

lsof | grep gnome

I think you need to be more specific with the fuser command; if I use my home folder i get this:

Code:

tuttle@shangrila:~$ fuser -a /home/tuttle
/home/tuttle:         7634c  7660c  7662c  7666c  7693c  7713c  7715c  7717c  7720c  7721c  7738c  7739c  7746c  7747c  7748c  7749c  7750c  7751c  7752c  7753c  7754c  7755c  8633c  8639c  8645c  8646c  8647c  8648c  8650c  8652c  8653c  8657c  8676c  8681c  8682c  8683c  8685c  8692c  8694c  8695c  8698c

The "c"'s mean "current directory" according to the man page.
More verbose and with "-m" option:

Code:

tuttle@shangrila:~$ fuser -mu /home
/home:                7634c(tuttle)  7660c(tuttle)  7662c(tuttle)  7666c(tuttle)  7693c(tuttle)  7713c(tuttle)  7715c(tuttle)  7717c(tuttle)  7720c(tuttle)  7721c(tuttle)  7738c(tuttle)  7739c(tuttle)  7741(tuttle)  7746c(tuttle)  7747c(tuttle)  7748c(tuttle)  7749c(tuttle)  7750c(tuttle)  7751c(tuttle)  7752c(tuttle)  7753c(tuttle)  7754c(tuttle)  7755c(tuttle)  7756(tuttle)  7757(tuttle)  7776(tuttle)  8639  8639c(tuttle)  8645  8645c(tuttle)  8646  8646c(tuttle)  8647  8647c(tuttle)  8648  8648c(tuttle)  8650  8650c(tuttle)  8652  8652c(tuttle)  8653  8653c(tuttle)  8657c(tuttle)  8676c(tuttle)  8681  8681c(tuttle)  8682  8682c(tuttle)  8683  8683c(tuttle)  8685  8685c(tuttle)  8692c(tuttle)  8694c(tuttle) 8695c(tuttle)  8698c(tuttle)  8782c(tuttle)  8831c(tuttle)  8872c(tuttle)  8875c(tuttle)

Now with -v:

Code:

tuttle@shangrila:~$ fuser -mv /home

edit: the -m option refers to a mounted file system, ie. all files used in that partition (I think).
