How to export files from MongoDb GridFS
(written by lawrence krubner, however indented passages are often quotes). You can contact lawrence at: lawrence@krubner.com, or follow me on Twitter.
by Vladimir Momirov: This is an awesome script:
The biggest problem is that I used GridFS to store uploaded files. After unsuccessfully searching online I decided to write my own bash export script. How to export all the files out of mongodb gridfs? Here’s the script:
#! /bin/bash
_host=”${1:?Usage: gridfs host db}”
_db=”${2:?Usage: gridfs host db}”
while read -r line; do
file=$(echo “$line” | awk -F’\t’ ‘{ print $1 }’)
[[ $file == ‘connected to’* ]] && continue
directory=${file%/*}
mkdir -p $directory
mongofiles -h $_host -db $_db get $file
done < <(mongofiles -h $_host -db $_db list) Script takes two parameters, first one is the hostname of the mongodb instance and the second is database. For example: ./gridfs localhost scen will export all files from scen database on localhost to current directory, if you have directory structure in GridFS, it will create that directories too.
