Would really like to figure out how to get this to do the equation so as not to have the 'division by zero' error when one or two variables have an empty string. I've tried a bunch of things such as adding '1' to each variable and trying to make it up elsewhere, but each time the values are incorrect.
...
Thats why I prefer functions:

EDIT:
But you still need to figure out a way to 'remove the option' to pass an empty string.
And without knowing how/where you get those strings, we can not help.
I need to compare two files with exactly same length as example: -
File1 contain 500 records with length of 640 chars of each line.
File2 contain 1500 records with length of 640 chars of each line.
I need get an output to be written in File3 which will contain 1000 records difference.

Need a script that manipulates a fixed length file that will compare 2 fields in that file and if they are equal write that line to a new file.
i.e. If fields 87-93 = fields 119-125, then write the entire line to a new file. Do this for every line in the file. After we get only the fields... (1 Reply)
I have two very large datasets (>100MB) in a simple vertical list format. They are of different size and with different order and formatting (e.g. whitespace and some other minor cruft that would thwart easy regex).
Let's call them set1 and set2.
I want to check set2 to see if it contains... (2 Replies)
Hi,
Can anyone help with a effective solution ?
I need to change a variable length text field (between 1 - 18 characters) to a fixed length text of 18 characters with the unused portion, at the end, filled with spaces.
The text field is actually field 10 of a .csv file however I could cut... (7 Replies)
Hello,
Is there anyway that I can align a pipe delimited text file by the maxium field length where the field is separated out by pipes for large text files with more than
100,000 rows?
So, far I have searched other forums and google about aligning text files in unix and I have noticed that... (7 Replies)
I am trying to get text from a webpage, in terminal form. So far I am:

3. this is where I am sort of lost. I know where in the printed line I... (7 Replies)

strverscmp
STRVERSCMP(3) Linux Programmer's Manual STRVERSCMP(3)NAME
strverscmp - compare two version strings
SYNOPSIS
#define _GNU_SOURCE
#include <string.h>
int strverscmp(const char *s1, const char *s2);
DESCRIPTION
Often one has files jan1, jan2, ..., jan9, jan10, ... and it feels wrong when ls orders them jan1, jan10, ..., jan2, ..., jan9. In order
to rectify this, GNU introduced the -v option to ls(1), which is implemented using versionsort(3), which again uses strverscmp.
Thus, the task of strverscmp is to compare two strings and find the "right" order, while strcmp only finds the lexicographic order. This
function does not use the locale category LC_COLLATE, so is meant mostly for situations where the strings are expected to be in ASCII.
What this function does is the following. If both strings are equal, return 0. Otherwise find the position between two bytes with the
property that before it both strings are equal, while directly after it there is a difference. Find the largest consecutive digit strings
containing (or starting at, or ending at) this position. If one or both of these is empty, then return what strcmp would have returned
(numerical ordering of byte values). Otherwise, compare both digit strings numerically, where digit strings with one or more leading
zeroes are interpreted as if they have a decimal point in front (so that in particular digit strings with more leading zeroes come before
digit strings with fewer leading zeroes). Thus, the ordering is 000, 00, 01, 010, 09, 0, 1, 9, 10.
RETURN VALUE
The strverscmp() function returns an integer less than, equal to, or greater than zero if s1 is found, respectively, to be earlier than,
equal to, or later than s2.
CONFORMING TO
This function is a GNU extension.
