I would like to create a script for calculating size and remaining space of a directory automatically every 24 hours, then send an email to report to the admin.
* POSIX and PERL are preferred.
Can anyone help, please? (1 Reply)
Hi,
Is there any way to calculate the size of a built in data type without using 'sizeof' operator? I also don't have the option to read it from std .h file.

Hi All,
I am very new to shell scripting. I have a text file which is the output of another utility. This text file has a list of SAF files which is basically a list of orphan attachments in the attachments directory. Now I want to read each file name from the file, get its size and repeat this...

Hi
I know that to see the size of the lun I need to give the command as "bootinfo -s hdisk*"
Can any one assist me with a script which if run will get the size of all the luns allocated to the server. The output of the script should be something like the one below :
hdisk0 size = 24GB... (2 Replies)
Hey guys.....
I have many files (lets say 100 or more) of same size, and I want to create a new output file and calculate the average of first row fifth column in all files and print it in first row of output file, then 2nd row fifth col in all 100 files and print it in 2nd row of output... (1 Reply)

Can anyone explain what each line of the code does and how it works? I have no experience with python so I am not sure how the arrays and such work. I found this code while looking through the forums.

sum
sum(1) General Commands Manual sum(1)NAME
sum - Displays the checksum and byte count in block-size (1024) units of a file
SYNOPSIS
sum [-o | -r] [file...]
The sum command reads file and calculates a 16-bit checksum and the byte count in block-size (1024) units in the file. If the file argu-
ment is omitted, sum reads standard input.
STANDARDS
Interfaces documented on this reference page conform to industry standards as follows:
sum: XCU5.0
Refer to the standards(5) reference page for more information about industry standards and associated tags.
OPTIONS
[Tru64 UNIX] Uses an algorithm to compute the checksum using word-by-word computation. Uses an alternate algorithm to compute the check-
sum (rigorous byte-by-byte computation rather than the word-by-word computation).
[Tru64 UNIX] This is the default.
OPERANDS
The file for which a checksum is to be computed. If this operand is omitted, standard input is used.
DESCRIPTION
The checksum and number of blocks are written to standard output. The sum command is generally used to determine if a file that was copied
or communicated over transmission lines is an exact copy of the original. The sum command writes the space used in 1024-byte units.
[Tru64 UNIX] The checksum is calculated using a rigorous byte-byte computation by default.
System V Compatibility
[Tru64 UNIX] The checksum algorithms for the default sum command and the SVID 2 compliant sum command are reversed. The SVID 2 compliant
sum command uses the word-by-word algorithm by default and uses the byte-by-byte algorithm if you specify the -r option on the command
line.
NOTES
The sum utility is marked LEGACY in XCU Issue 5. [Tru64 UNIX] The default algorithm is no longer the word-by-word computation algorithm.
It was changed to the 4.3BSD default algorithm. The algorithms used may not be portable, that is, the same checksum may not be produced
for the same input on different systems. Portable applications should use cksum.
EXIT STATUS
The following exit values are returned: Successful completion. An error occurred.
EXAMPLES
To display the checksum of datafile and the number of blocks in this file, enter: sum datafile
If the checksum of datafile is 1605 and if the file contains 3 blocks, sum displays: 1605 3 datafile
ENVIRONMENT VARIABLES
The following environment variables affect the execution of sum: Provides a default value for the internationalization variables that are
unset or null. If LANG is unset or null, the corresponding value from the default locale is used. If any of the internationalization vari-
ables contain an invalid setting, the utility behaves as if none of the variables had been defined. If set to a non-empty string value,
overrides the values of all the other internationalization variables. Determines the locale for the interpretation of sequences of bytes
of text data as characters (for example, single-byte as opposed to multibyte characters in arguments). Determines the locale for the for-
mat and contents of diagnostic messages written to standard error. Determines the location of message catalogues for the processing of
LC_MESSAGES.
