Recursively find top 20 largest files (> 1MB) sort human readable format
Search for files and list the 20 largest. $ find . -type f gives us a list of file, recursively, starting from here (.) $ -print0 | xargs -0 du -h separate the names of files with NULL characters, so we're not confused by spaces then xargs run the du command to find their size (in human-readable form -- 64M not 64123456) $ | sort -hr use sort to arrange the list in size order. sort -h knows that 1M is bigger than 9K $ | head -20 finally only select the top twenty out of the list

Get your colorized grep output in less(1). This involves two things: forcing grep to output colors even though it's not going to a terminal and telling less to handle those properly.

Use a Gmail virtual disk (GmailFS) on Ubuntu
Packages: gmailfs fuse-utils libfuse2 gvfs-fuse Config files: /etc/gmailfs/gmailfs.conf; ~/.gmailfs.conf (make a copy from the another one) Unmount: $ fusermount -u /mount/path/ /etc/fstab (Optional): none /mount/path/ gmailfs noauto,user[,username=USERNAME,password=PASSWORD,fsname=VOLUME] 0 0 NOTES: - The options between [] are optional since they already setuped on the config files. - The '-p' flag shows a prompt for the password entry. - It's necessary to add the user to the 'fuse' group. You can do that with: $ sudo chgrp fuse /dev/fuse and $ sudo usermod -a -G fuse USER - The volume name is not needed but highly recommended to avoid file corruption. Also choose a non-trivial name. - Google doesn't approve the use of Gmail account other than e-mail purposes. So, I recommend the creation of a new account for this.
