如何查找和计算在“查找”中找到的目录和文件

Question

How to find and count directory and files found in find util in Bash Linux, and put in env. variable, or print out, or both, each eg

NUM_FILE=
NUM_DIR=

of: (just illustration)

find . -type d ...... -o type f .......... -print..... # ???

Answer 1

Assuming that your directory/filenames don't contain newlines, piping the output of the find command into wc -l gives you the total number.

Using the usual command substitution, var=$(....) , puts the figure into a variable.

Answer 2

When you want to count a file with newlines only once, print a dot for every file:

NUM_FILE=$(find . -type f -printf "." | wc -c)
NUM_DIR=$(find . -type d -printf "." | wc -c)
