colcrt command in Linux with examples
colcrt command in Linux systems is used to format the text processor output so that it can be viewed on Cathode Ray Tube displays. It removes underlining, strike-throughs and underscores, which can’t be displayed on CRTs since only one character can be produced at a given location on the CRT screen. It also places all the underscores on a new line, right under the original line.
