digdagコマンドが fish 互換無かったときにしたこと

Last updated at Posted at 2017-10-18

仕事で digdag を使う機会があった。
その当時はデフォルトで fish サポートしてくれておらず悲しい気持ちになった。

digdag インストール

以下、digdag.ioより抜粋
※環境変数を設定する3つめのコマンドは fish 仕様に修正してある

$ curl -o ~/bin/digdag --create-dirs -L "https://dl.digdag.io/digdag-latest"
$ chmod +x ~/bin/digdag
$ echo 'set -gx PATH $HOME/bin $PATH' >> ~/.config/fish/config.fish

叩いてみると

$ digdag -v
Failed to execute process '/Users/xyxyxy/bin/digdag'. Reason:
exec: Exec format error
The file '/Users/xyxyxy/bin/digdag' is marked as an executable but could not be run by the operating system.

このオペレーティングシステムでは動かないとのこと...

fish を退出して実行

$ digdag -v

動く。

bash からコマンドを叩ければ問題ないらしい

$ echo "alias digdag '/bin/bash ~/bin/digdag'" >> ~/.config/fish/config.fish

解決。

余談だけど最新のバージョンでは改善されてるみたい。
