This command is using the textql tool to execute a SQL query on two CSV files. Here is the breakdown of each part of the command:
textql
: This is the command to run the textql tool.-header
: Specifies that the CSV files have a header row that contains the column names.-sql "SELECT * FROM ${file1} JOIN ${file2} ON ${file1}.${c1} = ${file2}.${c1} LIMIT ${10}"
: Specifies the SQL query to execute. It selects all columns (*
) from the two input CSV files (${file1}
and${file2}
) and performs an inner join on the column${c1}
from both files. TheLIMIT ${10}
clause limits the output to the first 10 rows.-output-header ${filename1-csv} ${filename2-csv}
: Specifies the output file names for the joined result.${filename1-csv}
and${filename2-csv}
are placeholders that will be replaced with the actual file names.
In summary, this command is using textql to perform a join operation on two CSV files based on a specific column and outputting the result to new CSV files.
