Export ArangoDB values to bash script

Question

I have a bash script that needs the count of records/documents that exist for a given arango collection. This seemed easy enough, I used the following arangosh call:

records=$(docker exec -it arango arangosh --javascript.execute scripts/getCount.js $collection --server.password '')

which then runs the following script:

#!/usr/bin/arangosh --javascript.execute 

var collection = ARGUMENTS[0];
var doc = db[collection];

var c = doc.count();
print(c);

This appears to work, but when I echo $records I get the correct value but it appears bolded. This leads to other reading issues so I redirected the docker exec call to cat -v and got the following output:

^[[1m#####^[[0m^M

The #### is my record value and it is correct. How do I either properly print the value out of arangosh or out of docker exec? Or is the only path to strip these hidden ansi characters from my value?

UPDATE:

I was able to attempt docker exec -it arango arangosh and attempt the command db._collection('my_collection').count() directly. This returned a bolded value which I believe means that it contains the hidden characters (arangosh doesn't have cat defined so I couldn't verify 100%).

With that said I believe the question is, can this be exported in plain text or do I need to sed substitute these characters after my script receives the response?

Answer 1

Still hoping for a better answer but I was able to get what I needed with the following:

imported=`docker exec -it arango arangosh --javascript.execute scripts/getRecords.js $collection --server.password '' | cat -v | sed 's/\(\^\[\[1m\)//g;s/\(\^\[\[0m^M\)//g'`

This simply passed the verbose output from docker to a sed substitution. Considering that for this script I expect the characters to be the same for all collections I am supplying to this script this should do the trick (just very limited).
