Question

各ファイルペアの一致する文字列が常に同じ場所にあると仮定すると、このオプションが提案されます。

# loop over the files that start with 'cf-'
for f in cf-*.txt; do
  # extract the unique "code", e.g 'tcg'
  code=$(echo "$f" | cut -d'-' -f5)

  # match the looped file with the one that starts with the "code"
  echo "diff" *"-${code}"* "${code}"*.txt

  # perform your commands, in this case I use an `echo` to show
  # how the command `diff` will be executed
done
