Total size of the contents of all the files in a directory [closed]

Answer 1

This may help:

ls -l| grep -v '^d'| awk '{total = total + $5} END {print "Total" , total}'

The above command will sum total all the files leaving the directories size.

Answer 2

Use:

$ du -ckx <DIR> | grep total | awk '{print $1}'

Where <DIR> is the directory you want to inspect.

The '-c' gives you grand total data which is extracted using the 'grep total' portion of the command, and the count in Kbytes is extracted with the awk command.

The only caveat here is if you have a subdirectory containing the text "total" it will get spit out as well.

Answer 3

stat's "%s" format gives you the actual number of bytes in a file.

 find . -type f |
 xargs stat --format=%s |
 awk '{s+=$1} END {print s}'

Feel free to substitute your favourite method for summing numbers.

Answer 4

For Win32 DOS, you can:

c:> dir /s c:\directory\you\want

and the penultimate line will tell you how many bytes the files take up.

I know this reads all files and directories, but works faster in some situations.

Answer 5

du is handy, but find is useful in case if you want to calculate the size of some files only (for example, using filter by extension). Also note that find themselves can print the size of each file in bytes. To calculate a total size we can connect dc command in the following manner:

find . -type f -printf "%s + " | dc -e0 -f- -ep

Here find generates sequence of commands for dc like 123 + 456 + 11 +. Although, the completed program should be like 0 123 + 456 + 11 + p (remember postfix notation).

So, to get the completed program we need to put 0 on the stack before executing the sequence from stdin, and print the top number after executing (the p command at the end). We achieve it via dc options:

1. -e0 is just shortcut for -e '0' that puts 0 on the stack,
2. -f- is for read and execute commands from stdin (that generated by find here),
3. -ep is for print the result (-e 'p').

To print the size in MiB like 284.06 MiB we can use -e '2 k 1024 / 1024 / n [ MiB] p' in point 3 instead (most spaces are optional).

Answer 6

cd to directory, then:

du -sh

ftw!
