I must have my thoughts crossed as for the life of me I can't seem to figure out this regex in BASH using a parameter expansion.
I want to search for 2 or more dashes and then replace with one dash. Here is what I thought would work, but doesn't.
string="Hello-World! #debug command---line"
string="${title//[-]{2,3}/-}"
#bash #regex #askfedi #AskFediverse
