This will take a list and winnow it to a single alpha word from its interior

Not optimized. Worked on January 9, 2021.

TRIM LINE NUMBERS AND SPACES FROM LEFT

cat notes-TESTING-every-Assert-in-DOI.txt | sed 's_[0-9]\+[\ :]\+[\ :]\+\(.*\)_\1_' | sort > ASSERT-cleaned-list-DOI.txt

FURTHER TRIM LEFT UP UNTIL EXACT STRING "assert" BEGINS

cat ASSERT-cleaned-list-DOI.txt | sed 's_.*->\(assert.*\)_\1_' | sort > ASSERT-1000sorted-raggedrightmargin.txt

GIMME NOTHIN BUT A SINGLE "WORD"

cat ASSERT-1000sorted-raggedrightmargin.txt | sed 's_\([[:alpha:]]\+\)(.*_\1_' | sort | uniq > ASSERT-3000-verbs-allTrimmed.txt
