Hey,
I currently have a set of captured sessions thru ethereal, saved in pflog files, basically its a tcpdump, which i need to go thru and sort the applications/protocols in order of the times they were used. I also need to change the headers of the packets, basically the source and destination... (0 Replies)
Hi,
I have two variables - A and B - containing a bunch of file paths. I am comparing them and when I find a match I want to remove that entry from A so that as the compare proceeds A shrinks entry by entry.
How can I remove a matched entry from A whilst leaving the non matched entries... (6 Replies)

Hi guys
Firstly, I'd like to say hi and how great this forum is. I'm not new to UNIX but am relatively new to scripting. I have a personal project that I'm working on just to try and speed up my learning.
I working with a text file, well more of a logfile really. It has several columns of... (6 Replies)
Hi,
I have several text files. One main file contains the detail data, other have some information to extract data from the main file, and some are empty files. Examples are shown below:
The main file look like:

I have a list of files, 4 files for example
Then I have two buffers ifa and ifb giving me the file numbers
from which I need to get a group of data. For example, the first
four groups use file 1. The fifth group uses data from file 1 and
file 2.
I am thinking of storing all the data in the... (1 Reply)
Dear friends,
I'm struggling to preparing a bunch of gromacs input files, say manually. It's really a time-consuming work without any techniques. I suppose that it could be done by a smart script automatically. But I lack some basic knowledge on scripting. Please help!
My original input looks... (3 Replies)
I have a process that requires me to read data from huge log files and find the most recent entry on a per-user basis. The number of users may fluctuate wildly month to month, so I can't code for it with names or a set number of variables to capture the data, and the files are large so I don't... (7 Replies)

total
TOTAL(1) General Commands Manual TOTAL(1)NAME
total - sum up columns
SYNOPSIS
total [ -m ][ -sE | -p | -u | -l ][ -i{f|d}[N] ][ -o{f|d} ][ -tC ][ -N [ -r ]] [ file .. ]
DESCRIPTION
Total sums up columns of real numbers from one or more files and prints out the result on its standard output.
By default, total computes the straigt sum of each input column, but multiplication can be specified instead with the -p option. Likewise,
the -u option means find the upper limit (maximum), and -l means find the lower limit (minimum).
Sums of powers can be computed by giving an exponent with the -s option. (Note that there is no space between the -s and the exponent.)
This exponent can be any real number, positive or negative. The absolute value of the input is always taken before the power is computed
in order to avoid complex results. Thus, -s1 will produce a sum of absolute values. The default power (zero) is interpreted as a straight
sum without taking absolute values.
The -m option can be used to compute the mean rather than the total. For sums, the arithmetic mean is computed. For products, the geomet-
ric mean is computed. (A logarithmic sum of absolute values is used to avoid overflow, and zero values are silently ignored.)
If the input data is binary, the -id or -if option may be given for 64-bit double or 32-bit float values, respectively. Either option may
be followed immediately by an optional count, which defaults to 1, indicating the number of double or float binary values to read per
record on the input file. (There can be no space between the option and this count.) Similarly, the -od and -of options specify binary
double or float output, respectively. These options do not need a count, as this will be determined by the number of input channels.
A count can be given as the number of lines to read before computing a result. Normally, total reads each file to its end before producing
its result, but this behavior may be overridden by inserting blank lines in the input. For each blank input line, total produces a result
as if the end-of-file had been reached. If two blank lines immediately follow each other, total closes the file and proceeds to the next
one (after reporting the result). The -N option (where N is a decimal integer) tells total to produce a result and reset the calculation
after every N input lines. In addition, the -r option can be specified to override reinitialization and thus give a running total every N
lines (or every blank line). If the end of file is reached, the current total is printed and the calculation is reset before the next file
(with or without the -r option).
The -tC option can be used to specify the input and output tab character. The default tab character is TAB.
If no files are given, the standard input is read.
EXAMPLE
To compute the RMS value of colon-separated columns in a file:
total -t: -m -s2 input
To produce a running product of values from a file:
total -p -1 -r input
BUGS
If the input files have varying numbers of columns, mean values will certainly be off. Total will ignore missing column entries if the tab
separator is a non-white character, but cannot tell where a missing column should have been if the tab character is white.
