\nRecently I got into a situation where I ran out of free space on my Ubuntu instance. The first thing you need to do is to check how much available space you have. The command below will give you the general idea.\n<\/p>\n
\r\ndf -h\r\n<\/pre>\n<\/p>\n
\nTo list the files\/directories that take up most of the space use the following. You can make your system to show you more files by changing “-n 10” to “-n 20” etc.\n<\/p>\n
\r\nsudo du -a \/ | sort -n -r | head -n 10\r\n\r\n47286901 \/\r\n42315676 \/var\r\n41550196 \/var\/log\r\n41534640 \/var\/log\/jenkins\r\n28101588 \/var\/log\/jenkins\/jenkins.log\r\n13432208 \/var\/log\/jenkins\/jenkins.log.1\r\n2978220 \/home\r\n2978216 \/home\/deploy\r\n1589784 \/home\/deploy\/www\r\n1499948 \/usr\r\n<\/pre>\n\nAnother command that will give you a good idea about the space allocated is:\n<\/p>\n
\r\nsudo du -cha --max-depth=1 \/var | grep -E \"M|G\"\r\n<\/pre>\n\nYou can decide how deep to go by changing “–max-depth” value\n<\/p>\n
<\/p>\n
\nIn order to get a better visual representation and more user friendly interface, you can install ncdu – an Ubuntu disk usage viewer package\n<\/p>\n
\r\nsudo apt-get install ncdu\r\n<\/pre>\n<\/p>\n
