Example data:
--download "https://git.io/fj5hF" --output=duplicates.csv
--download "https://git.io/fj5ju" --output=duplicates-deletion.json
Basic commands:
--list # list all projects
--list -H 127.0.0.1 -P 80 # specify hostname and port
--create duplicates.csv # create new project from file
--info "duplicates" # show project metadata
--apply duplicates-deletion.json "duplicates" # apply rules in file to project
--export "duplicates" # export project to terminal in tsv format
--export --output=deduped.xls "duplicates" # export project to file in xls format
--delete "duplicates" # delete project
Some more examples:
--info 1234567890123 # specify project by id
--create example.tsv --encoding=UTF-8
--create example.xml --recordPath=collection --recordPath=record
--create example.json --recordPath=_ --recordPath=_
--create example.xlsx --sheets=0
--create example.ods --sheets=0
