概要

fish shellからembulk, digdagが実行できなかったので調べました。
※bashなら普通に実行できるので、embulk, digdagの実行の時だけbashを使うという手もある

対応

参考にしたサイトには下記の様に書かれてあった。

fish shellでembulkとかdigdagとか使っていると実行スクリプトにシバンが書かれていないのでエラーになる

直接実行してもダメだが

~> .embulk/bin/embulk
Failed to execute process '.embulk/bin/embulk'. Reason:
exec: Exec format error
The file '.embulk/bin/embulk' is marked as an executable but could not be run by the operating system.

java -jar で実行ならいける

~> java -jar .embulk/bin/embulk
Embulk v0.9.16
Usage: embulk [-vm-options] <command> [--options]
Commands:
   mkbundle   <directory>                             # create a new plugin bundle environment.
   bundle     [directory]                             # update a plugin bundle environment.
   run        <config.yml>                            # run a bulk load transaction.
   cleanup    <config.yml>                            # cleanup resume state.
   preview    <config.yml>                            # dry-run the bulk load without output and show preview.
   guess      <partial-config.yml> -o <output.yml>    # guess missing parameters to create a complete configuration file.
   gem        <install | list | help>                 # install a plugin or show installed plugins.
   new        <category> <name>                       # generates new plugin template
   migrate    <path>                                  # modify plugin code to use the latest Embulk plugin API
   example    [path]                                  # creates an example config file and csv file to try embulk.
   selfupdate [version]                               # upgrades embulk to the latest released version or to the specified version.

                                     Expect side effects by running your external script at your own risk.)
   -J-O                             Disable JVM optimizations to speed up startup time (enabled by default if command is 'run')
   -J+O                             Enable JVM optimizations to speed up throughput
   -J...                            Set JVM options (use -J-help to see available options)

※digdagも同様の挙動でした。
