. chars are 1-based
Method: 2 sort keys, applied one after another
sort -k 1.1,1.1 -k 1.2
Grouping: FROM field 1, char 1 TO field 1, char 1
Key 1: -k 1.1,1.1
Sorting inside groups : field 1, char 2

³ delete lines #
whole lines beginning with <
1^<.*\n?
2# ^ = start of line
3# < = literal <
4# .* = rest of line
5# \n? = also remove the newline so you don’t leave blank lines
delete any empty line (even lines with spaces):
1^\s*\n
2# ^\s* matches zero or more whitespace chars from the start of the line
3# \n removes the actual newline
only truly empty lines (no spaces):
1^\n
³ find foo OR bar #
