How about being able to select both the column to be printed in field 1 of the output, and the suffix of the fields to use for the calculations? Try

Hello there,
how do i multiply a fraction and a whole number? Example 20% of 50,000.
I had gotten 0.2 using the following:
chk=echo 20 100 | awk `{print $1/$2}`
echo $chk
$chk \* 50000 displays the error: non-numeric expression. (1 Reply)
Suppose i have a file A
1*2*3*4
2*4*4*22
and second file B
2*3*4*5
4*4*6*7
By multiplying file A by file B that is file A by first column in file B respectively
output shud be
2*6*12*20
8*16*24*154
my code is
=$1
next
}

Hi,
I am writing a script in Bourne shell

used=`quota -v | tail -1 | awk '{print $2}'`
total=`quota -v | tail -1 | awk '{print $3}'`
echo "$used"
echo "$total"
perc=`expr ${used} / ${total} * 100 | bc`
echo "$perc"
I want to get a percentage of quota used to total limit

Hi,
I would like to carry out a multiplication in a for loop but some how I get always zero. The result of the multiplication must be assigned to the variable x.
Here is teh code
for (( i=1;i<=15;i++)); do
x=$( printf "%s\n " 'scale = 10; i*5.0*335.0*3.0/1000.0' | bc)

Hi all, newbie here.
Does anyone know if it is possible to use GCC or Clang to multiply
two unsigned numbers and have it use for intel instructions, the mull instruction or an imul. I can't figure how to word this to accomplish this task:

Hi,
I can't find out how to create correct code to get multiplication of each elements of array. Let's say I enter array into command line (2 3 4 5 6 8) and i need output 2*3*4*5*6*8=5760.
I tried this one, but answer is 0.

Hello all,
I have square matrices that look like the following, I want to merge these matrices together, and add the file names as headers. This is a simple example with two variables, actually I have ~1500 variables and 10 files.
The order of variables in the matrices are consistent.

I have two files. Row id in File1 matches the column id in file2 (starting from column7 )except the last 2 characters. File1 has 50 rows and File 2 has 56 columns. If the id matches I want to multiply the value in column3 of File1 to the entire column in File2. and in the final output print only... (11 Replies)
How can I produce this kind of output?
Enter a number: 3
MULTIPLICATION TABLE:
0 1 2 3
1 1 2 3
2 2 4 6
3 3 6 9
When you enter a number, it should show you the corresponding multiplication table. Plus we need to use for loops that I do not actually know. Thanks in advance! Here is my... (2 Replies)

col
COL(1) User Commands COL(1)NAME
col - filter reverse line feeds from input
SYNOPSIS
col [options]
DESCRIPTION
col filters out reverse (and half-reverse) line feeds so the output is in the correct order with only forward and half-forward line feeds,
and replaces white-space characters with tabs where possible. This can be useful in processing the output of nroff(1) and tbl(1).
col reads from standard input and writes to standard output.
OPTIONS -b, --no-backspaces
Do not output any backspaces, printing only the last character written to each column position.
-f, --fine
Forward half line feeds are permitted fine mode. Normally characters printed on a half-line boundary are printed on the following
line.
-p, --pass
Force unknown control sequences to be passed through unchanged. Normally, col will filter out any control sequences from the input
other than those recognized and interpreted by itself, which are listed below.
-h, --tabs
Output tabs instead of multiple spaces.
-x, --spaces
Output multiple spaces instead of tabs.
-l, --lines number
Buffer at least number lines in memory. By default, 128 lines are buffered.
-V, --version
Output version information and exit.
-H, --help
Output help and exit.
NOTES
The control sequences for carriage motion that col understands and their decimal values are listed in the following table:
ESC-7 reverse line feed (escape then 7)
ESC-8 half reverse line feed (escape then 8)
ESC-9 half forward line feed (escape then 9)
backspace moves back one column (8); ignored in the first column
newline forward line feed (10); also does carriage return
carriage return (13)
shift in shift to normal character set (15)
shift out shift to alternate character set (14)
space moves forward one column (32)
tab moves forward to next tab stop (9)
vertical tab reverse line feed (11)
All unrecognized control characters and escape sequences are discarded.
col keeps track of the character set as characters are read and makes sure the character set is correct when they are output.
If the input attempts to back up to the last flushed line, col will display a warning message.
SEE ALSO expand(1), nroff(1), tbl(1)STANDARDS
The col utility conforms to the Single UNIX Specification, Version 2. The -l option is an extension to the standard.
HISTORY
A col command appeared in Version 6 AT&T UNIX.
AVAILABILITY
The col command is part of the util-linux package and is available from Linux Kernel Archive <ftp://ftp.kernel.org/pub/linux/utils/util-
