====== GENERIC LINUX COMMANDS ======

===== RENAME 'The' ROMS =====
1. Dry-run preview (generates rename list without executing):
<code>
  find /mnt/DOCS1/ROMs/Library/roms -type f -name "*, The*" | sort | while IFS= read -r filepath; do
      dir=$(dirname "$filepath")
      filename=$(basename "$filepath")
      if echo "$filename" | grep -qP '^\w.*\+.*[,] The '; then
          newname=$(echo "$filename" | sed 's/$+ $$.*$, The $.*$/\1The \2 \3/')
      else
          newname=$(echo "$filename" | sed 's/^$.*$, The $.*$$/The \1 \2/')
      fi
      echo "$dir | '$filename' -> '$newname'"
  done
</code>

2. Execute renames:
<code>
  find /mnt/DOCS1/ROMs/Library/roms -type f -name "*, The*" | sort -u | while IFS= read -r filepath; do
      dir=$(dirname "$filepath")
      filename=$(basename "$filepath")
      # Special case: combo pack where ", The" belongs to a subtitle within the combo
      if echo "$filename" | grep -qP '^\w.*\+.*[,] The '; then
          newname=$(echo "$filename" | sed 's/$+ $$.*$, The $.*$/\1The \2 \3/')
      else
          newname=$(echo "$filename" | sed 's/^$.*$, The $.*$$/The \1 \2/')
      fi
      if [ "$filename" != "$newname" ]; then
          mv -- "$filepath" "$dir/$newname"
          echo "Renamed: $filename"
      fi
  done
</code>

Key sed patterns:

- Standard: s/^$.*$, The $.*$$/The \1 \2/ — captures everything before , The  as \1 and everything after as \2, then prepends The
  - Combo pack: s/$+ $$.*$, The $.*$/\1The \2 \3/ — moves The to before the subtitle within a +-delimited combo title
