well, i would say, that the maximum number of directories is based on your inode numbers of that filesystem..
i am not sure if there is a limit, but i have one costumer with more than 1 million files in one directory and it works... it's very slow, some commands take up to 5 minutes like "ls", but it works
regards pressy
btw: it took about 8 minutes to create these 30.000 directories
OS - Sun OS7
What sources can I go to to figure out what is the maximun number of processes for OS7 with 2GB of memory.
I believe it is 64K processes, but this number reflects resources being swaped.
Any help is appreciated

Hi, i have a file with numbers in it and i was wondering if there's a script i could use to find the max number and have that printed to a new file?
example a.txt
18
26
47
34
27
so find the max number in a.txt and print it to b.txt.
Thanks! (17 Replies)
Hello all,
I'm looking to implement a Linux server that will host up to 60 simultaneous X sessions, all running firefox to a secured web interface.
Does anyone have any experience sizing a system like this?
The reason for the setup isn't as important (Since I really don't understand why... (1 Reply)
Is there a simple way of calculating the max number in a set of variables, so
a=1
b=3
c=6
d=30
something that says
e=max($a, $b, $c, $d)
I've found a way to do it using:
a="1"
b="3"
c="5"
d="50"
if ;
then
t=$a

pivot_root
PIVOT_ROOT(8) System Administration PIVOT_ROOT(8)NAME
pivot_root - change the root filesystem
SYNOPSIS
pivot_root new_root put_old
DESCRIPTION
pivot_root moves the root file system of the current process to the directory put_old and makes new_root the new root file system. Since
pivot_root(8) simply calls pivot_root(2), we refer to the man page of the latter for further details.
Note that, depending on the implementation of pivot_root, root and cwd of the caller may or may not change. The following is a sequence for
invoking pivot_root that works in either case, assuming that pivot_root and chroot are in the current PATH:
cd new_root
pivot_root . put_old
exec chroot . command
Note that chroot must be available under the old root and under the new root, because pivot_root may or may not have implicitly changed the
root directory of the shell.
Note that exec chroot changes the running executable, which is necessary if the old root directory should be unmounted afterwards. Also
note that standard input, output, and error may still point to a device on the old root file system, keeping it busy. They can easily be
changed when invoking chroot (see below; note the absence of leading slashes to make it work whether pivot_root has changed the shell's
root or not).
OPTIONS -V, --version
Display version information and exit.
-h, --help
Display help text and exit.
EXAMPLES
Change the root file system to /dev/hda1 from an interactive shell:
mount /dev/hda1 /new-root
cd /new-root
pivot_root . old-root
exec chroot . sh <dev/console >dev/console 2>&1
umount /old-root
Mount the new root file system over NFS from 10.0.0.1:/my_root and run init:
ifconfig lo 127.0.0.1 up # for portmap
# configure Ethernet or such
portmap # for lockd (implicitly started by mount)
mount -o ro 10.0.0.1:/my_root /mnt
killall portmap # portmap keeps old root busy
cd /mnt
pivot_root . old_root
exec chroot . sh -c 'umount /old_root; exec /sbin/init'
<dev/console >dev/console 2>&1
