List files in directory and print months statistics with total size in bytes

This AWK script can list files in directory and print number of files in single months with total size in bytes.

About

Script uses ls to list files in directory and stat to get unix time of modification (creation if your system supports it) and size in bytes. Then script will save all this info and in the end pretty print this to the terminal.

Usage

After downloading this repository give executable permission to awk script:
chmod +x list_files_in_months.awk

Then you can run it with:
./list_files_in_months.awk
or
./list_files_in_months.awk /my/directory

Changing the default directory time type

• Change the default directory in line dir = "/home/matej/" to your own.
• If your system supports time of birth use %W instead of %Y in line "stat --printf=\"%Y %s\" \"" dir filename "\"" | getline info

Example of usage

$ ./list_files_in_months.awk /home/matej
Listing directory: /home/matej
