for example
1.
there is only two file in /home/test/
# ls -l /home/test/
total 8
-rw-r--r-- 1 root wheel 2 Mar 3 23:29 a.txt
-rw-r--r-- 1 root wheel 3 Mar 3 23:29 b.txt
So the total size of all files ( a.txt + b.txt ) should be 5 Bytes.
How to get total size ( 5 Bytes ) directly but not the 8 Bytes.
2.
# man du
says,
-h "Human-readable" output. Use unit suffixes: Byte, Kilobyte,
Megabyte, Gigabyte, Terabyte, Petabyte, Exabyte in order to
reduce the number of digits to four or less.
but
# du -h /home/test
6.0K /home/test
How to let unit suffixes: Byte display (come out) but not Kilobyte?
just like
# du -b /home/test ( option "-b" not exist)
5B /home/test
