textql

Execute SQL against structured text like CSV or TSV files. More information: https://github.com/dinedal/textql.

• Print the lines in the specified CSV file that match an SQL query to stdout:

textql -sql "SELECT * FROM filename" path/to/filename.csv

• Query a TSV file:

textql -dlm=tab -sql "SELECT * FROM filename" path/to/filename.tsv

• Query file with header row:

textql -dlm=delimiter -header -sql "SELECT * FROM filename" path/to/filename.csv

• Read data from stdin:

cat path/to/file | textql -sql "SELECT * FROM stdin"

• Join two files on a specified common column:

textql -header -sql "SELECT * FROM path/to/file1 JOIN file2 ON path/to/file1.c1 = file2.c1 LIMIT 10" -output-header path/to/file1.csv path/to/file2.csv

• Format output using an output delimiter with an output header line:

textql -output-dlm=delimiter -output-header -sql "SELECT column AS alias FROM filename" path/to/filename.csv
