Word-based diff on reformatted text files

It can be hard to spot differences in reformatted files, because of all the diff noise created by word wrapped lines. This command removes all the noise and performs a word-by-word diff. To ignore empty lines, add -B to the diff command. Also, if this is something you do often, you might want to check out the wdiff(1) program.

Check These Out

Show IP Address in prompt --> PS1 var

when working with many machines in a computer lab need to know the IP addr is very large, this is a simplistic solution to make things easier

Copy the full path of a file to the clipboard (requires xclip or similar)

Handy for those times you need to paste a file path in an IDE or some other app. sudo apt-get install xclip Then, for convenience, alias xclip to 'xclip -selection c' so you can just do something like realpath . | xclip

phpdoc shortcut

A shortcut to generate documentation with phpdoc. Defaults to HTML; optionally to PDF if third argument is given. Stores documentation in cwd under ./docs/. I forget the syntax to the output, -o, option, so this is easier.

Create a new file

Change gnome-shell wallpaper

Terminal - Show directories in the PATH, one per line with sed and bash3.X `here string'

another method : awk '{gsub(/:/, "\n");print}'

ssh batch jobs: query hundreds of hosts with an ssh command

Need to query hundreds of hosts with an ssh command ? Of course you'll have setup keys on all your remote HOSTs. But in the case a key is not present this command will skip that node, proceeding on to the next. -t: Force pseudo-tty allocation. This can be used to execute arbitrary screen-based programs on a remote machine. Also prevents unwanted stty messages being sent to console -q: Quiet mode. -o "BatchMode yes" If set to yes, passphrase/password querying will be disabled. This option is useful in scripts and other batch jobs where no user is present

List docker volumes by container

pulsed terminal clock

"Pretty print" $PATH, separate path per line
