Description:
Write a Bourne Shell Program which
accepts one to many filenames on the command line. The program will compute the
number of characters, words, and lines in each file. The program will also
calculate the total number of characters, words, and lines found in all of the
files. For this program you may NOT use the built-in "wc"
program. Also, this program does not allow any switches or options on the
command line. You need to perform error checking for valid filenames.
Sample Execution:
The output of the program should be
as follows:
$my_wc
file1 file2
file1 stats:
Number characters: 251
Number words: 65
Number lines: 34
file2 stats:
Number characters: 456
Number words: 89
Number lines: 67
Complete stats:
Total number characters: 707
Total number words: 154
Total number lines: 101
