Linux – get file size and line count at the same time

linuxlsstatwc

I'm looking for a way to list all files in a directory, with both their size, and a line count. Right now I'm using stat -c \"%s %n\" /directory/* to get file names and sizes, and I know I can use find /directory/ -type f -exec wc -l {} + to get file name and line count, but is there any way I can get both at the same time?

You are almost there.

find directory -type f -exec wc -lc {} +

will get file name, line count, and character count.

Strictly speaking, -c (a.k.a. --bytes) is documented as counting bytes, which is probably what you want. There is also a -m (a.k.a. --chars) option for counting “characters”. From the choice of the m option letter, I guess this counts multi-byte characters; e.g., Unicode characters. There is also a -w option for actually counting words.

Shell – How to get exact file size and file name

As others have noted, if this is a dynamic web application, you're much better off using PHP's functions for accessing file size.

But if you're going to get it by executing a shell command, don't use ls. Instead, use stat, and tell it exactly what you want:

$ stat -c '%n %s' x.txt
x.txt 12

List a directory, including subdirectories, with file count and cumulative size

If I understand you correctly, this will give you want you want:

find /path/to/target -type d | while IFS= read -r dir; do 
  echo -ne "$dir\tsize: $(du -sh "$dir" | cut -f 1)" 
  echo -ne "\tsubdirs: $(find "$dir" -mindepth 1 -type d | wc -l)"
  echo -e "\tfiles: $(find "$dir" -type f | wc -l )";
done  | tac

If you run this on /boot for example, you get output like this:

/boot/burg/themes/sora_extended size: 8.0K  subdirs: 0  files: 1
/boot/burg/themes/radiance/images   size: 196K  subdirs: 0  files: 48
/boot/burg/themes/radiance  size: 772K  subdirs: 1  files: 53
/boot/burg/themes/winter    size: 808K  subdirs: 0  files: 35
/boot/burg/themes/icons size: 712K  subdirs: 0  files: 76
/boot/burg/themes   size: 8.9M  subdirs: 26 files: 440
/boot/burg/fonts    size: 7.1M  subdirs: 0  files: 74
/boot/burg  size: 20M   subdirs: 29 files: 733
/boot/grub/locale   size: 652K  subdirs: 0  files: 17
/boot/grub  size: 4.6M  subdirs: 1  files: 224
/boot/extlinux/themes/debian-wheezy/extlinux    size: 732K  subdirs: 0  files: 11
/boot/extlinux/themes/debian-wheezy size: 1.5M  subdirs: 1  files: 22
/boot/extlinux/themes   size: 1.5M  subdirs: 2  files: 22
/boot/extlinux  size: 1.6M  subdirs: 3  files: 28
/boot/  size: 122M  subdirs: 36 files: 1004

To have easy access to this command, you could turn it into a function. Add these lines to your shell's initialization file (~/.bashrc for bash):

dirsize(){
    find "$1" -type d | while IFS= read -r dir; do 
    echo -ne "$dir\tsize: $(du -sh "$dir"| cut -f 1)" 
    echo -ne "\tsubdirs: $(find "$dir" -mindepth 1 -type d | wc -l)"
    echo -e "\tfiles: $(find "$dir" -maxdepth 1 -type f | wc -l )";
    done  | tac
}

You can now run it as dirsize /path/.

Explanation

The function above has 5 major parts:

find /path/to/target -type d | while IFS= read -r dir; do ... ; done : This will find all directories under /path/to/target and process each of them by setting the variable dir to their name. The IFS= ensures this won't break on directories with spaces in their names.
echo -ne "$dir\tsize: $(du -sh "$dir" | cut -f 1)" : This uses the command du to get the directory's size and cut to print only the first field of du.
echo -ne "\tsubdirs: $(find "$dir" -mindepth 1 -type d | wc -l)" : This find command looks for subdirectories of $dir. The type -d ensures we only find directories, no files and the -mindepth makes sure we do not count the current directory, ..
echo -e "\tfiles: $(find "$dir" -maxdepth 1 -type f | wc -l)"; : This one looks for files (-type f) that are directly (-maxdepth 1) under $dir. It will not count files that are in subdirectories of $d.
| tac : Finally, the whole thing is passed through tac which simply reverses the order in which lines are printed. This means that the total size of the target directory will be shown as the last line. If that is not what you want, simply delete | tac.
