textql

Execute SQL against structured text like csv or tsv files.

More information.

• Print the lines in the specified `.csv` file that match a SQL query to stdout:

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

• Query `.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 {file1} JOIN {file2} ON {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}
