One-liners

# This isn't REALLY a one-liner per-se, just a wildly effecient timesaver.
#   But it did save my ass on a tight deadline when I didn't have supporting automation ready yet
#  `pbcopy` (and its friend, `pbpaste`) are works of art.

 # I'm using this to make an excel/sheets equation easier to read
 # Take what's in your clipboard and replace it with the same thing minus newlines and spaces

# Export a sensitive variable you're tired of typing but don't wanna expose in your command history
# Optionally: read -s VAR_NAME if your dingus terminal writes recent history to disk too
read VAR_NAME; export VAR_NAME="${VAR_NAME}"

#Quick-ass temp folder with date stamp
TODAY=`date +%Y%m%d`; mkdir temp-${TODAY}; cd temp-${TODAY};
#tbh this is probably wildly inefficient but I have that TODAY=`date blah blah` chunk update as part of my ZSH theme
# It's always ready that way.
