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 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
