Christmas song for UNIX hackers:

better !pout !cry
better watchout
lpr why
santa claus < north pole > town

cat /etc/passed > list
ncheck list
ncheck list
cat list | grep naughty > nogiftlist
cat list | grep nice > giftlist
santa claus < north pole > town

who | grep sleeping
who | grep awake
who | egrep 'bad|good'
for (goodness sake) {
be good
}

With the brand new Microsoft C++ compiler, what you see in the debugger, is not always what you get...

TIL:

- AWK was based on egrep, and the idea was borrowed from sed - an extended sed of sorts

- My cat really loves green onions. She's chewing on her third as I write this.

What an interesting day, full of curious discoveries.

Man, people have the weirdest fetishes for using the most unreadable acrobatic shell garbage you have ever seen.

Some StackOverflow answers are hilarious, like the question could be something like "how do I capture regex groups and put them in a variable array?".

The answer would be some multiline command using every goddamn character possible, no indentation, no spaces to make sense of the pieces.

Regex in unix is an unholy mess. You have sed (with its modes), awk, grep (and grep -P), egrep.
I'll take js regex anytime of the day.

And everytime you need to do one simple single goddamn thing, each time it's a different broken ass syntax.

The resulting command that you end up picking is something that you'll probably forget in the next hour.

I like a good challenge, but readability is important too.

Or maybe I have very rudimentary shell skills.

reading code:

grep -E or egrep?

Use
git branch --merged
to get, you guessed it, all the branches you have merged.

Use
git branch -d <branch-name>
To delete a branch if it has been merged (use -D for forced)

And Use,
git branch --merged | egrep - v "(^\*|master|dev)" | xargs git branch - d

To delete all the branches that you have merged (but not anything with master/dev in their names)

Sorry for the formatting, I don't know how coder formatting works on DR..
