Any advice on how to resolve multiple CSV header issues?

We are getting multiple errors like this

Corrupt csv header in CSV file , 2 columns with the same name

However we have so many CSV files that finding them will be all but impossible.

 

Can someone provide advice on how to find them?

Assuming that your OS is unix/linux, assuming that your CSV files use standard filenaming conventions (i.e. *.csv), assuming that your CSV files are standard with a header on the first line, assuming that the source files still exist, you can use the following CLI commands to identify problematic files:

find ${SPLUNK_HOME}/etc/apps/*/lookups -name *.csv -exec head -1 {} \; | tr ',' '\n' | sort| uniq -d

This will tell you the duplicated field, e.g. "foo".  Then take that and do this to find the file (or a small pile to peek through):

for FILE in $(find ${SPLUNK_HOME}/lookups -name *.csv -exec grep -il foo {} \;); do echo ${FILE}; head -1 ${FILE} | tr ',' '\n' | sort | uniq -d; done

Here are some other tips:

So the first one command, every word it brings back is a duplicated one?

Exactly.

Well see we are trying to find specific keywords, so I know like one I'm trying to test. When I run your second command, it pulls in a ton of CSV files. Checking one, and the word isn't in the CSV header at all?

Oh I see it now, the word is in the CSV file itself. But I'm only concerned with the headers, is that not what the alert means?
