bash function to "highlight" tabs and linebreaks

I don't think it's possible to give a (background) colour to the tab itself, since a tab is, IIUC, simply a command to the terminal to move to the right. Nevertheless, this "highlighting" can be helpful when working with tab-separated files. Show Sample Output
This is sample output - yours may be different.
```
$ echo -e 'foo\tbar\nfie\tfum'|hl-nonprinting 
foo&#9657;    bar&#8267;

Removes single line from known_hosts file

Quickly remove the conflicting line (key) from current users known_hosts file when there is an SSH host conflict. Very nice when you get tired of writing out full commands. Ideally you would place this into your .bash_profile Usage: rhost [n] Example: rhost 33 (removes line 33 from ~/.ssh/known_hosts) Function assumes the $HOME exists, you could alternatively use "~/.ssh/known_hosts" Mac OSX likes a space for sed -i "$1" d

rhost() { if [[ $1 =~ ^[0-9]+$ ]]; then sed -i "$1"d ${HOME}/.ssh/known_hosts; else echo "rhost [n]"; fi }

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"

Simple addicting bash game.

hold period (or whatever character) and hit enter after a second. You need to make the next line of periods the same length as the previous line... score starts at 0 and increase each time length of line is same.

recursive search and replace old with new string, inside files

recursively traverse the directory structure from . down, look for string "oldstring" in all files, and replace it with "newstring", wherever found also: $ grep -rl oldstring . |xargs perl -pi~ -e 's/oldstring/newstring'

List only directories, one per line

omit the 1 (one) if you don't need one-per-line

Automatically tunnel all ports of running docker instances in boot2docker

It requires https://jqplay.org/, that comes with brew: brew install jq

Find all folder in /var that contains log in their path and have more than 10 files inside them, print the folder and the count

-L is for following symbolic links, it can be omitted and then you can find in your whole / dir

generate random password

generate password

Find the package that installed a command

Delete more than one month old thumbnails from home directory

By time thumbnail images in ~/thumbnails take up too much space, this command will help deleting old ones. Find options explained: -type f : find files only, not directories -atime +30 : last accessed more than 30 days ago

Flush and then immediately start watching a file

This is useful for keeping an eye on an error log while developing. The !^ pulls the first arg from the previous command (which needs to be run in a sub-shell for this shortcut to work).
