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 {} +

exec chmod to subfiles
Using `-exec cmd {} +` causes find to build the command using all matching filenames before execution, rather than once per file.

Rename files in batch

Poor man's unsort (randomize lines)

Which processes are listening on a specific port (e.g. port 80)
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

quickly backup or copy a file with bash
less symbols, tab completion. including # export SIMPLE_BACKUP_SUFFIX="_`date +%F`" in your .bashrc provides you to easily timestamp your files

Create a PNG screenshot of Rigol Ultravision scopes attached per LAN
Scope should have the Rigol Ultravision Technology otherwise it won't accept the command. ImageMagic is required. Scope sends a 1.1M BMP file and converted to PNG it's only 18-20K

Find the package that installed a command

find which lines in a file are longer than N characters
Filter out lines of input that contain 72, or fewer, characters. This uses bash only. ${#i} is the number of characters in variable i.

Then pipe to 'xargs ls' for a familiar listing, possibly using find's -print0 and xarg's -0 options.
