Find all the links to a file
This command finds and prints all the symbolic and hard links to a file. Note that the file argument itself be a link and it will find the original file as well. You can also do this with the inode number for a file or directory by first using stat or ls or some other tool to get the number like so: $ stat -Lc %i file or $ ls -Hid file And then using: $ find -L / -inum INODE_NUMBER -exec ls -ld {} +

dd with progress bar and statistics
This command utilizes 'pv' to show dd's progress. Notes on use with dd: -- dd block size (bs=...) is a widely debated command-line switch and should usually be between 1024 and 4096. You won't see much performance improvements beyond 4096, but regardless of the block size, dd will transfer every bit of data. -- pv's switch, '-s' should be as close to the size of the data source as possible. -- dd's out file, 'of=...' can be anything as the data within that file are the same regardless of the filename / extension.
