check if there are files that need fixing

grep -R 'title: ".*".*"$' . | tee malformed-titles.txt

(util) strip stuff that grep -R adds

cat malformed-titles.txt | sed 's/.*\.md://' |

(util) only keep filenames

cat malformed-titles.txt | sed 's/:.*//'

check that no existing files that would break -> this should be empty!

grep -R '/^title: [^"]*$' . | tee conflicting-lines.txt

(util) replace inline “make sure the previous check is empty!”

sed -i \
-e '/^title: ".*".*"$/s/"//g' \
-e '/^title: [^"]*$/s/title: \(.*\)/title: "\1"/'
  • replace only where title: " <has a double quote here> "
    • remove all quotes
  • find title: without quote
    • add quotes at beginning and end of string title

create script with one command per file to fix using the previous sed command

cat malformed-titles.txt | sed 's/:.*//' | sed 's!^\(.*\)!sed -i .bak -e '"'"'/^title: ".*".*"$/s/"//g'"'"' -e '"'"'/^title: [^"]*$/s/title: \\(.*\\)/title: "\\1"/'"'"' "\1"! ' > fix.sh

run with

zsh fix.sh

speedrun

grep -R 'title: ".*".*"$' . | sed 's/:.*//' | sed 's!^\(.*\)!sed -i "" -e '"'"'/^title: ".*".*"$/s/"//g'"'"' -e '"'"'/^title: [^"]*$/s/title: \\(.*\\)/title: "\\1"/'"'"' "\1"! ' | zsh
