Shell Programming and Scripting

1) I need a shell code to count the number of files ( without directories or sub-directories ) in a directory given as arguments I tried this code but it didn't work , maybe I tried the wrong one:

numOfFiles=`find $1 -type f -maxdepth 1 | wc -l`

I found it in another thread in this site..

2) also I need a code to get the number of bytes consumed by the files in this directory
Please , can you help me ?

You have your file parameter mixed up with the directory parameter. A nice hint:

Code:

numOfFiles=`find . -maxdepth 1 -mindepth 1 -type f -name "$1" | wc -l`

No need for an external command:

Code:

#!/bin/bash

dir=${1:-.}

shopt -s nullglob

nfiles()
{
  numfiles=$#
}

nfiles "$dir/"*
files=$numfiles

nfiles "$dir/"*/
dirs=$numfiles

printf "Files: %d\n" "$(( $files - $numfiles ))"
printf " Dirs: %d\n" "$dirs"

Try this

Code:

#!/bin/bash
dir=${1:-.}
numFiles=0
totSize=0
for i in "$dir/"*;do
  dir=`file $i | grep directory`
  if [ ! -z "$dir" ];then
    continue;
  fi
  fsize=`stat -c %s $i`
  ((totSize=totSize+fsize))
  ((numFiles=numFiles+1))
done
echo "Num of Files  : $numFiles"
echo "Tot File Size : $totSize"

thank you all for help :
Ahmed I tried your code , it works but it always give me the same result:

Num of Files : 0
Tot Files Size : 0

I called the script count .. and I made a directory " new " with 3 files in it ..
when I called it in terminal " ./count new "
the results " 0 , 0 " .

can you please check it , or I have to try something else ?

you have to call the script with the directory you want as argument
for eg:- you want the details of the files in the directory /usr/home/test
you need to call it like this

Code:

./count /usr/home/test

if the argument is not given, it will print the details of the current directory.

You need to give the full path if the script and the directory is not in the same directory

Num of Files : 0
Tot Files Size : 0
