Add dash at the end and beginning of a string

Question

I want a dash to be added at the end and beginning of a string.

Example:

"chicken" -> "-chicken-"  
"nuggets" -> "-nuggets-"

So I'm pretty much asking for Regexes.

`sed s/.*/-&-/`. At least try next time. - Replace `.` with `[^ \t]` if you define a string as stuff between whitespace. — ShellFish, Jun 15 '15 at 19:48

You can use the following to match:

^|$

And replace with - (dash)

See DEMO

PS: Use it with m (multiline) flag.

The regex is:

/^(.*)$/-\1-/

But why don't you add dashes without regex? I mean, why not to use string operators? Like str = '-' + str +'-'; or $str = "-" . $str . "-", etc. depending on your programming language.
