Question

Write a shell script program called “countf.sh” that will count how many files or directories recursively. It will either take arguments for specific directories and no argument. If no argument, it will read the current working directory as the starting point. Please also provide –h option to print out how to use your countf.sh program. % ./countf.sh % ./countf.sh dir1 dir2 .... %./countf.sh –h hints: I would write a script function to process a count for each directory and return a number of files to be added up.

Explanation / Answer

#!/bin/bash #countf.sh #this file counts the number of files and directories in a path recursively #Variables declare -i filecount="0" declare -i dircount="0" for file in /* do if [ -f $file ] then $((filecount++)) elif [ -d $file ] then $((dircount++)) fi done echo The number of files is "$filecount" echo The number of directories is "$dircount" echo $?
