Directory Monitoring Tool 📁

A simple bash tool for monitoring the size of objects inside a directory.

How to run 🏃

Make dir_monitoring_util.sh executable

cmhod +x dir_monitoring_util.sh

Run in the background and without creating nohup.out file

nohup ./dir_monitoring.sh TARGET_DIR=/home/geo/test_dir LIMIT_SIZE_MB=1 REFRESH_PERIOD=20 REMOVE_LARGE_FILES=true >/dev/null 2>&1 & 

Script parameters:

• TARGET_DIR (string): The path of the directory which you want to monitor.(default value=empty)
• LIMIT_SIZE_MB (integer): The max number(Mb) of the files/dirs which you want to keep in the target dir (default value=100)
• REFRESH_PERIOD (interger): The refreshing period of the tool in seconds (default value=60)
• REMOVE_LARGE_FILES (boolean): true if you want to delete the files/dirs higher than the LIMIT_SIZE_MB and false if you want to keep them and only log the event. (default value=false)

Example 🔨

Let's take an example. Run the tool with TARGET_DIR=\target_dir & LIMIT_SIZE_MB=100. Before the tool run:

\
|__target_dir\
   |__directory_one
   |__diretory_two
   |__directory_three
   |  |__directory_four
   |     |__large_file (file size 200Mb)
   |__small_file (file size: 19Mb)

After the run of the tool:

\
|__target_dir\
   |__directory_one
   |__diretory_two
   |__small_file (file size: 19Mb)

Notes ❗

• The log file is in /home/user/logs/dir_monitoring_util.log.
• Doesn't work with directories with numbers in the names (e.x dir_1).
• Loop in the sub-directories of the TARGET_DIR, not nested checks.
• Check the permissions of the folders if you want also to drop them.
• Can monitor files/dirs more than 1Mb LIMIT_SIZE_MB>=1.
