Script finding the total size of a directory and checking if a directory exists
0
I need one additional line for my script that finds the total size of a directory and shows it in bytes and another line in the beginning of this script that checks if a directory exists.
That's my script so far:
#!/bin/bash
directory="$dir"
echo "Directory name: "
read directory
if ...checking if a directory exists... then
echo "Number of subdirectories: "
ls $dir -l| grep ^d| wc -l
echo "Number of ordinary files: "
find $dir -maxdepth 1 -type f | wc -l
echo "Number of ordinary files with size 0: "
find $dir -size 0 -type f | wc -l
echo "Total size of this directory: "
find ...finding the total size of a directory in bytes...
fi
echo "The specified directory does not exist"
bash scripting directory

And this should give you the last piece of the problem (see the primary expressions section): tldp.org/LDP/Bash-Beginners-Guide/html/sect_07_01.html

K. got it. Now I want to write a line that checks if a directory exists: if [ -d "$dir" ]; then script and it works but it also shows code after "fi" if a directory exists. In my case: script, echo "The specified directory does not exist". Why does it also show echo after fi if a directory exist?

It's because theechostatement is outside theif .. fiblock, which means it is unaffected by your condition. To make it conditional, you can use an else block:if [cond]; then ... else .. fi.
