q: Query `.csv` file by specifying the delimiter as ','.
$ q -d',' "SELECT * from ${filename}"
try on your machine
This command is using the "q" command-line tool to execute a SQL query on a CSV file. Let's break it down:
- "q" is a command-line tool that allows you to run SQL-like queries on CSV, TSV, and JSON files.
- "-d','" specifies the delimiter used in the CSV file. In this case, it's a comma (',').
- "SELECT from ${filename}" is the SQL query being executed. "${filename}" is a placeholder that represents the actual name of the CSV file. The asterisk () symbol is used to select all columns from the table in the CSV file.
In summary, the command is using the "q" tool to select all columns from the CSV file specified by the "${filename}" placeholder, with the delimiter set to comma.
