Here is the sentence I found the word.
わしはむかし丹{たん}下{げ}段{だん}平{ぺい}とはちがうんだ わかってくれ
いまいったすじのいい若いのにわしゃあ命{いのち}をかけとるんだ わしの先生命だ!
I have tried searching for some web sites e.g. Jisho.org, dictionary.goo.ne.jp or weblio.jp but there is no where refer to the meaning of it.
I guess it might be meaning as 'right now' or 'present time' but I have no idea what the word 「いった」means.
