I guess that I will try one more time... /proc is an illusion. It does not actually consume disk space.
If you create a new process with, say pid 1234 and it is using 300 MB of memory, /proc/1234 will magicly pop into existence and it will be 300 MB in size. But you did not lose any disk space. Not one byte.
Now, kill pid 1234 and /proc/1234 will vanish. But you won't get back even one byte of disk space. /proc/1234 is just a way to treat a process as if it was a data file. This makes stuff like debuggers very easy to write.
/dev, on the other hand, is probably a real problem. It is usually caused by someone doing something like:
tar cvf /dev/wrong-name-for-tape-drive /big/collection/of/files
Maybe:
find /dev -type f
will find it for you.

I wrote a wrapper (call it prog1) around another program (call it prog2) for security purposes.

Inspite of me deleting huge files in a filesystem(AIX 5.3) in oracle folder, the filesystem when i check using df -k still shows 100% full. Does that mean there is a process still pointing to the files which i deleted. how do i work around this.

app::clusterssh::host
App::ClusterSSH::Host(3pm) User Contributed Perl Documentation App::ClusterSSH::Host(3pm)
NAME
ClusterSSH::Host - Object representing a host.
SYNOPSIS
use ClusterSSH::Host;
my $host = ClusterSSH::Host->new({
hostname => 'hostname',
});
my $host = ClusterSSH::Host->parse_host_string('username@hostname:1234');
DESCRIPTION
Object representing a host. Include details to contact the host such as hostname/ipaddress, username and port.
METHODS
$host=ClusterSSH::Host->new ({ hostname => 'hostname' })
Create a new host object. 'hostname' is a required arg, 'username' and 'port' are optional. Raises exception if an error occurs.
$host->get_hostname
$host->get_username
$host->get_port
$host->get_master
Return specific details about the host
$host->set_username
$host->set_port
$host->set_master
Set specific details about the host after its been created.
get_realname
If the server name provided is not an IP address (either IPv4 or IPv6) attempt to resolve it and retun the discovered names.
get_givenname
Alias to get_hostname, for use when " get_realname " might return something different
parse_host_string
Given a host string, returns a host object. Parses hosts such as
check_ssh_hostname
Check the objects hostname to see whether or not it may be configured within the users $HOME/.ssh/config configuration file
host
192.168.0.1
user@host
user@192.168.0.1
host:port
[1234:1234:1234::4567]:port
1234:1234:1234::4567
and so on. Cope with IPv4 and IPv6 addresses - raises a warning if the IPv6 address is ambiguous (i.e. in the last example, is the
4567 part of the IPv6 address or a port definition?) and assumes it is part of address. Use brackets to avoid seeing warning.
