Top Forums Shell Programming and Scripting Question about working with data to create new column Post 302133050 by scottzx7rr on Tuesday 21st of August 2007 06:33:25 PM

vgersh99,

Thanks for the swift reply. I appreciate your assistance. I hate being very rusty and trying to relearn something. LOL Question would that work also for doing a multiple series of math? Meaning I have a column that I want to do math upon. I am taking the column and multiplying it by 0.125, then that total will be subtracted by 1, then that total will be multiplied by 0.0225 for the final total.

((Column*0.125)-1)*0.0225=new column

Meaning would I be able to do something like this:

BEGIN {
FS=OFS=","
}

{
format="%0" length($2) "d"
$(NF+1)=sprintf(format, ((($4*0.125)-1)*0.0225))
print
}

NAME
neaten - neaten up output columns SYNOPSIS
neaten [ format ] DESCRIPTION
Neaten reads from its standard input and neatens up columns separated by white space using the specified format. The format is a string consisting of a positive integer followed by an alignment character and another integer. The alignment character is usually a decimal point ('.'), but it can be any non-digit. The alignment character is used as the central point of each column. The total column field width will be the number to the left of the alignment character plus one for the alignment character itself plus the number to the right of the alignment character. If a field does not contain the alignment character, it will be printed to the left of where the alignment character would have appeared. If a field is too long to print within the specified format, the entire field will be printed and that row will not be aligned with the rest. The default format is "8.8". EXAMPLE
To examine a file with columns of numbers: neaten 10.8 < input | more BUGS
Columns wider than the total width of the format specification will be printed without any separating white space. The program does not do anything special with tabs on the input. AUTHOR
