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:

DESCRIPTION
The prop_string family of functions operate on a string value property object type.
prop_string_create(void)
Create an empty mutable string. Returns NULL on failure.
prop_string_create_cstring(const char *cstring)
Create a mutable string that contains a copy of cstring. Returns NULL on failure.
prop_string_create_cstring_nocopy(const char *cstring)
Create an immutable string that contains a reference to cstring. Returns NULL on failure.
prop_string_copy(prop_string_t string)
Copy a string. If the string being copied is an immutable external C string reference, then the copy is also immutable and references
the same external C string. Returns NULL on failure.
prop_string_copy_mutable(prop_string_t string)
Copy a string, always creating a mutable copy. Returns NULL on failure.
prop_string_size(prop_string_t string)
Returns the size of the string, not including the terminating NUL. If the supplied object isn't a string, zero is returned.
prop_string_mutable(prop_string_t string)
Returns true if the string is mutable. If the supplied object isn't a string, false is returned.
prop_string_cstring(prop_string_t string)
Returns a copy of the string's contents as a C string. The caller is responsible for freeing the returned buffer.
In user space, the buffer is allocated using malloc(3). In the kernel, the buffer is allocated using malloc(9) using the malloc type
M_TEMP.
Returns NULL on failure.
prop_string_cstring_nocopy(prop_string_t string)
Returns an immutable reference to the contents of the string as a C string. If the supplied object isn't a string, NULL is returned.
prop_string_append(prop_string_t str1, prop_string_t str2)
Append the contents of str2 to str1, which must be mutable. Returns true upon success and false otherwise.
prop_string_append_cstring(prop_string_t string, const char *cstring)
Append the C string cstring to string, which must be mutable. Returns true upon success and false otherwise.
prop_string_equals(prop_string_t str1, prop_string_t str2)
Returns true if the two string objects are equivalent.
prop_string_equals_cstring(prop_string_t string, const char *cstring)
Returns true if the string's value is equivalent to cstring.
