fdfind: A simple, fast and user-friendly alternative to 'find'
fd is a simple, fast and user-friendly alternative to
find.

While it does not seek to mirror all of find's powerful functionality, it provides sensible
(opinionated) defaults for 80% of the use cases.

Features
- Convenient syntax: fd PATTERN instead of find -iname '*PATTERN*'.
- Colorized terminal output (similar to ls).
- It's fast (see benchmarks below).
- Smart case: the search is case-insensitive by default. It switches to
  case-sensitive if the pattern contains an uppercase
  character*.
- Ignores hidden directories and files, by default.
- Ignores patterns from your .gitignore, by default.
- Regular expressions.
- Unicode-awareness.
- The command name is 50% shorter* than
  find :-).
- Parallel command execution with a syntax similar to GNU Parallel.

node.js - express.js - single routing handler for multiple routes in a single line - Stack Overflow
```
app.get('/:var(bla|blabla)?', todo)
```
:var sets the req.param that you don't use. it's only used in this case to set the regex.

(bla|blabla) sets the regex to match, so it matches the strings bla and blablah.

? makes the entire regex optional, so it matches / as well.

shell script - Using 'sed' to find and replace - Unix & Linux Stack Exchange
sed is stream editor, but can edit files directly too, with the following:
```
sed -i -e 's/foo/bar/g' filename
```
s is used to replace the found expression "foo" with "bar"

g stands for "global", meaning to do this for the whole line. If you leave off the g and "foo" appears twice on the same line, only the first "foo" is changed to "bar".

-i option is used to edit in place on filename.

-e option indicates a command to run.

3.1.2. Complete Expression for Deliverable Email Address

The following regular expression is a deliverable email address:

; Mailbox from RFC 5321, as amended
```
P E J DEA     = ([A-Za-z0-9!#-'*+\-/=?^_`{-~\xA0-\x{10FFFF}]+
(?:\.[A-Za-z0-9!#-'*+\-/=?^_`{-~\xA0-\x{10FFFF}])|
"(?:[ !#-\[\]-~\xA0-\x{10FFFF}]|\\[ -~])*")@
((?:[A-Za-z0-9](?:[A-Za-z0-9\-]*[A-Za-z0-9])?|
[\x00-\x{10FFFF}]*[\x80-\x{10FFFF}]+[\x00-\x{10FFFF}]*)
(?:\.(?:[A-Za-z0-9](?:[A-Za-z0-9\-]*
[A-Za-z0-9])?|[\x00-\x{10FFFF}]*
[\x80-\x{10FFFF}]+[\x00-\x{10FFFF}]*))*)
```
In the regular expression DEA, capturing group 1 is the local-part
production, and capturing group 2 is the domain production.

Replacing returns with a comma with tr

It's an interesting dilemma. There are two obstacles to doing this in sed. One is that sed operates line by line and never sees the newline endings. Second, sed's regular expressions don't provide a way to exactly match a newline character.

If you really want to do this, don't use sed; use tr.
