Sometimes, your Mac is filled up with files and you can’t seem to understand what really is taking much space. Here is how you can find out. - First of all find disk usage and save it to a log file. Also, find all big files that are there. Grepping using ‘G’ would find all files that are in GB. Also, save the second list to another file so that we are only doing it once. sh du -h > ~/space. log cat ~/space. log | awk '{print $1}' | grep 'G' > ~/highspace. log Next, open a split window and do sh cat ~/highspace. log And Now, start finding the ones which are big one by one. Let’s say one of the entry was 5.6G, Let’s find which one was it. ```sh cat ~/space. log | fgrep -f highspace. log #It will give something like this: 1.2G./.Android/avd/Nexus_6_API_21.avd 2.7G./.Android/avd 2.7G./.Android

following: ```sh sudo rm -rf Documents/Movie. avi ``` Voila! Repeat this process and remove all files and directories that you no longer need. # Disclaimer: Do it very patiently and backup everything that's important.
