Often times, there is a need to check the size of the sub-directories or files in a project, on a live or development server, or just at our local machine.
Here is a list of useful commands that you can leverage to make sure the available disk space of your machine is normal and that huge node_modules
directory size hasn't gone crazy :D
We will use the du command , which is explained below:
du (disc usage) command estimates file_path space usage The options -sh are (from man du): -s, --summarize display only a total for each argument -h, --human-readable print sizes in human readable format (e.g., 1K 234M 2G)
To check more than one directory and see the total, use du -sch:
-c, --total produce a grand total
So, let's see the basic commands:
Shows you the size of the directory in readable format:
$ du -sh directory/
Shows you a list with all the directories along with their sizes, ordered by size:
$ du -sh * | sort -h
Example in my example flutter project:
paul@paul-Inspiron-N5110:~/projects/flutter_test$ du -sh * | sort -h 4,0K android.iml 4,0K flutter_test_android.iml 4,0K flutter_test.iml 4,0K pubspec.yaml 4,0K README.md 8,0K test 12K lib 200K android 212K ios
Bonus:
Outputs the total and available size of your system's paritions
$ df -h
Outputs the inodes usage in your system:
$ df -i
