HI all,
I am in urgent need of this answer.
In TCP/IP protocol, If the IP datagram size > MTU of the any
routing network then the IP fragmentation takes place!
Where exactly the Fragmentation takes place? is it at the source network layer or in between at some router?
If so, which of the... (1 Reply)
Hi,
I have written one script to calculate total space of all file in one directory, ignoring subdirectory, it works fine.
Now, I've been trying to calculate all files which includes files in any subdirectories.
I use recursive function to do this, but it can work only if there is only one... (4 Replies)
All.
How can i calculate the fragmentation ratio on a mounted disk, given that i have no root privilege and i cannot switch to single user mode. (0 Replies)
I need to calcualte the size of a directory by the year the files in that directory were created .
For example the script will sum up, by year, the number of blocks for that directory and its' subdirectories for files created / accessed in that year.
I need a report that would look like... (11 Replies)

Hello :
I need some help in writing a ksh script which will find a particular directory in all the file systems in a server and finally report the total size of the direcotry in all the file systems.
Some thing like this..

Hello all, I am experiencing a problem with IP fragmentation.
I am receiving an udp packet that is larger than the MTU and it is fragmented along the network.
I am receiving the two fragments but they are not being reassembled correclty.
The MTU of the system is 1500 and I cannot increase it,... (2 Replies)
I am trying to use awk to calculate the average of all lines in $2 for every file in a directory. The below bash seems to do that, but I cannot figure out how to capture the string before the _ as the output file name and have it be tab-delimeted. Thank you :).

du(1) General Commands Manual du(1)NAME
du - summarize disk usage
SYNOPSIS
type] [name]...
DESCRIPTION
The command gives the number of 512-byte blocks allocated for all files and (recursively) directories within each directory and file speci-
fied by the name operands. The block count includes the indirect blocks of the file. A file with two or more links is counted only once.
If name is missing, the current working directory is used.
By default, generates an entry only for the name operands and each directory contained within those hierarchies.
By default, when a symbolic link is encountered on the command line or in the file hierarchy, will count the size of the symbolic link
rather than the file referenced by the link, and will not follow the link to another portion of the file hierarchy.
Options
The command recognizes the following options:
Print entries for each file encountered
in the directory hierarchies in addition to the normal output.
For each name operand that is a directory for which file system swap has been enabled, print the number of blocks the swap
system is currently using.
If a symbolic link is specified on the command line,
will count the size of the file or file hierarchy referenced by the link. Unlike the option, it will not follow sym-
bolic links encountered during the traversal of the directory hierarchy.
Gives the block count in 1024-byte blocks.
If a symbolic link is specified on the command line or
encountered during the traversal of a file hierarchy, will count the size of the file or file hierarchy referenced by
the link.
Print messages about directories that cannot be read,
files that cannot be accessed, and so on. is normally silent about such conditions.
Print only the grand total of disk usage
for each of the specified name operands.
Restrict reporting to file systems of the specified
type. (Example values for type are and so on.) Multiple options can be specified. Disk usage is normally reported
for the entire directory hierarchy below each of the given name operands.
Restrict reporting to only those files
that have the same device as the file specified by the name operand. Disk usage is normally reported for the entire
directory hierarchy below each of the given name operands.
According to the standards, specifying more than one of the mutually-exclusive options and will not be considered an error. The last
option specified will determine the behavior of the utility.
EXAMPLES
Display disk usage for the current working directory and all directories below it, generating error messages for unreadable directories:
Display disk usage for the entire file system except for any or mounted file systems:
Display disk usage for files on the root volume only. No usage statistics are collected for any other mounted file systems:
WARNINGS
Block counts are incorrect for files that contain holes.
