Thank you very much for the very clean code and the explanation on my script. My default shell is bash and your code worked perfectly.
One quick question, what does the following part mean
bunch of thanks again.
That line creates an array (f1[]) of the values found in the 1st column ($1) of the 1st input file (when FNR {the line number in the of the input lines read from the current file} is equal to NR {the line number of all input lines read from all files}) indexed by the current line number in the file (++fc1). Note that I could have used FNR as the index here, but I need to save the number of lines found in the 1st input file so we can use it in the for loop when we are processing the 2nd input file.

Hi guys,
I need help in extracting one column of numbers from two different files and display it in a output file. In specific, I want to extrac the column no.2 ($2) from each file, file1.txt, file2.txt. Then place both extracted columns in a one file, out.txt.

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

Hi,
This is something that probably it is more difficult to explain than to do.
I have two files e.g.

I need to multiply column1 and column3 data and need to compare it with column5. Need to check multiplication and Throw error if result is greater or less than column5 values, though difference of +/- 2 will be ok
Ex - if column1 has 2.4 and column3 has 3.5, it will be ok if column5 have value... (13 Replies)

paste(1) General Commands Manual paste(1)Name
paste - merge file data
Syntax
paste file1 file2...
paste -dlist file1 file2...
paste -s [-dlist] file1 file2...
Description
In the first two forms, concatenates corresponding lines of the given input files file1, file2, etc. It treats each file as a column or
columns of a table and pastes them together horizontally (parallel merging).
In the last form, the command combines subsequent lines of the input file (serial merging).
In all cases, lines are glued together with the tab character, or with characters from an optionally specified list. Output is to the
standard output, so it can be used as the start of a pipe, or as a filter, if - is used in place of a file name.
Options
- Used in place of any file name, to read a line from the standard input. (There is no prompting).
-dlist Replaces characters of all but last file with nontabs characters (default tab). One or more characters immediately following -d
replace the default tab as the line concatenation character. The list is used circularly, i. e. when exhausted, it is reused. In
parallel merging (i. e. no -s option), the lines from the last file are always terminated with a new-line character, not from the
list. The list may contain the special escape sequences:
(new-line), (tab), \ (backslash), and (empty string, not a null
character). Quoting may be necessary, if characters have special meaning to the shell (for example, to get one backslash, use
-d"\\" ).
Without this option, the new-line characters of each but the last file (or last line in case of the -s option) are replaced by a
tab character. This option allows replacing the tab character by one or more alternate characters (see below).
-s Merges subsequent lines rather than one from each input file. Use tab for concatenation, unless a list is specified with -d
option. Regardless of the list, the very last character of the file is forced to be a new-line.
Examples
ls | paste -d" " -
list directory in one column
ls | paste - - - -
list directory in four columns
paste -s -d"
" file
combine pairs of lines into lines
Diagnostics
line too long
Output lines are restricted to 511 characters.
too many files
Except for -s option, no more than 12 input files may be specified.
