["Ash Berlin-Taylor (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/AIRFLOW-3289?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16672996#comment-16672996 ] 

Ash Berlin-Taylor commented on AIRFLOW-3289:
--------------------------------------------

I suspect a work-around for now is to specify \{{\\\\N}} - there may be some escaping bug in the bash operator

> I want to call a sed command on csv file to replace empty values (,,) with \N.
> I can do it with the following bash command 
> {code:java}
> cat example.csv | sed 's;,,;,\\N,;g' > example_processed.csv{code}
> But when I try to do the same with airflow BashOperator, it substitutes ,, with N (instead of \N).
>  
> I attached the code and csv file to reproduce.
