# the above create files that are almost all zeros - if random bytes are desired
# then use: ~/Dev/Perl/randBytes 1048576 > 10MB.dat

Useful, I learned some tricks thanks ;)

show and ider finder on Yosemite works with this commands:

finderShowHidden: defaults write com.apple.finder AppleShowAllFiles -boolean true ; killall Finder
finderHideHidden: defaults write com.apple.finder AppleShowAllFiles -boolean false ; killall Finder

You did an amazing work.

Thank you.

@theGivingTree

Awesome effort you've made!

@ddramone

Love it.

thank you for a great set of aliases and functions. Also appreciate the detailed descriptions and nuanced sections.

@AnnAddicks

Thanks for extract! Frequently I have to look up all the command options I need!

@conorflynn

Thanks! Gotta love the shortcuts!

@nickkuijpers

Very nice indeed! Thanks!

@Coldmooon

Thanks! I'm using it.

@anmolgarg

Great Set! Here are a few additions I have in my bash profile.

### Make Terminal Better
alias lsd='ll | grep "^d"'          # Preferred 'ls' implementation (only directories)
alias restartdock='killall Dock'    # Restart dock

### Environment Config
export PROMPT_COMMAND='echo -ne "\033]0;${PWD##*/}\007"'    # Show working directory in tab

Thank you for taking the time to create this!

@mikecentola

Hell yes!!

@johnborges

Good stuff. I will be stealing many of these.

thecompyoda commented Aug 21, 2016 edited

Great script!! My terminal is MUCH better now!

A few things I changed in my fork:

  1. Editing & Sourcing .bash_profile multiple times in a single terminal session causes PATH to keep growing, re-adding the same directories to the PATH over and over.
  2. Closing and opening terminal, or having to issue the source command, to activate my changes

This is a really great script template, Ive use a large part of it into my own bash profile

@dlumma
dlumma commented Nov 26, 2016

Very cool script. Curious to hear if you have any opinion on https://www.iterm2.com/ ?

@Haijuk
Haijuk commented Jan 28, 2017

Thanks for your great collection!

Instead of:
alias myip='curl ip.appspot.com'
which isn't (currently?) working, I prefer:
alias myip='dig +short myip.opendns.com @resolver1.opendns.com'
Apparently more reliable and faster. (dig is usually installed by default on macOS)
