Question

The Perl module Term::Screen has a method for inserting a character and deleting a character. Both of these methods have an accompanying method to check if the interface allows for such actions [ic_exists() and dc_exists()]. I’m running this script through a ssh session and the ic_exists and dc_exists are returning 0, not available. What do I need to do to enable the insert character and delete character for this module?

Answer 1

Make sure that the TERM in your ssh environment is set to something that supports those functions (and is compatible with your terminal).

Try adding

print "$ENV{TERM}\n";

to your script to see what terminal it thinks it’s talking to.
