Text Query Tool (TQT)

TQT implements safe and simple version of some text filtering shell scripts' commands. It is safe and uniform kind of cat, cut, grep and sed calls and regex handling on the quality level and regex instruction set of Perl/Python (Perl-compatible regular expressions (PCREs)).

Usage

usage: tqt.py [-h] [-V] [-f FILE [FILE ...]] [-l LINES] [-e EXPRESSION [EXPRESSION ...]] [-D DELIMITER] [-F FIELDS] [-c] [-v] [-s SUBSTITUTE [SUBSTITUTE ...] | -i INSERT |
              -a APPEND | -d]
              {cat,cut,grep,sed}
