NAME
du - estimate file space usage
SYNOPSIS
du [OPTION]... [FILE]...
du [OPTION]... --files0-from=F
DESCRIPTION
Summarize disk usage of each FILE, recursively for directories.
Mandatory arguments to long options are mandatory for short options too.
-0, --null
end each output line with 0 byte rather than newline
-a, --all
write counts for all files, not just directories
--apparent-size
print apparent sizes, rather than disk usage; although the apparent size is usually smaller,
note: the easiest way to transfer data to a new phone is by using google drive. if you want to use a local backup, you will need to transfer the files to the new phone using a computer, file explorer or sd card. if your data is not stored on the /sdcard/whatsapp/ folder, you may see "internal storage" or "main storage" folders.。in case of computer displays,smaller monitors (14") may have a refresh rate of 60-72 hzlinux命令, while larger monitors (17" or 19") must ideally have a refresh rate of 85 hz or higher. with these larger monitors, if the refresh rate is set below 85 hz, people watching the screen may feel discomfort to their eyes.。 these ears may be of similar size and shape, or the anterior ear may be somewhat larger (the posterior ear is never larger than the anterior one)。
and the like
-B, --block-size=SIZE
scale sizes by SIZE before printing them; e.g., '-BM' prints sizes in units of 1,048,576
bytes; see SIZE format below
-b, --bytes
equivalent to '--apparent-size --block-size=1'
