I need to divide the number of white spaces by total number of characters in a file using bash. I am able to get the number of white spaces correctly using:
Code:
tr -cd [:space:] < afile | wc -c
I am also able to get the total number of characters using:
Code:
wc -c afile
How do I divide the first number by second to get the final answer.
Can anyone help please. I am writing a kourne shell script and I am unsure how to do the following:

wc(1) General Commands Manual wc(1)NAME
wc - count words, lines, and bytes or characters in a file
SYNOPSIS
[file]...
DESCRIPTION
The command counts lines, words, and bytes or characters in the named files, or in the standard input if no file names are specified. It
also keeps a total count for all named files.
A word is a string of characters delimited by spaces, tabs, or newlines.
Options
recognizes the following options:
Report the number of bytes in each input file.
Report the number of newline characters in each input file.
Report the number of characters in each input file.
Report the number of words in each input file.
The and options are mutually exclusive. Otherwise, the and or options can be used in any combination to specify that a subset of lines,
words, and bytes or characters are to be reported.
When any option is specified, reports only the information requested. If no option is specified, the default output is
When a file is specified on the command line, its name is printed along with the counts.
Standard Output
By default, the standard output contains an entry for each input file in the form:
newlines words bytes file
If the option is specified, the number of characters replaces the bytes field in this format.
If any option is specified, the fields for the unspecified options are omitted.
If no file operand is specified, neither the file name nor the preceding blank character is written.
If more than one file operand is specified, an additional line is written at the end of the output, of the same format as the other lines,
except that the word (in the POSIX locale) is written instead of a file name and the total of each column is written as appropriate.
Under UNIX Standard environment, a word is a string of characters delimited by spaces, tabs, newline, carriage-return, vertical tab, or
form-feed.
RETURN VALUE
exits with one of the following values:
Successful completion.
An error occurred.

WARNINGS

line character, the count will be off by one.
