i.MX6 ltib : bash - change horizontal scrolling to new line

When typing long commands that extend past the window shell geometry the default action in a minimum root file system is to horizontal scroll due to missing packages. This can be changed to instead add a new line for long command line user input. The packages readline and termcap should be enabled in the package selection of the root file system. The environment variable TERM in a Bash shell leverages readline and termcap for shell cursor control, which if are missing performs a default action of horizontal scrolling when long lines are entered.

See /etc/termcap for terminal definitions.

export TERM=wyse60

The wyse60 terminal has an UP definition, thus when typing a long line when at the end of line, the cursor control will return and linefeed.

export TERM=ansi

The ansi terminal will scroll left as the single long line is entered.

For further information refer to the manual pages:

  • readline and the variable horizontal-scroll-mode, also /etc/inputrc for defining.
  • termcap
