Question

When I run

screen

on the remote host(running Linux), I obtain the following error:

Cannot find terminfo entry for \'xterm-         


        

Answer 1

In the question, the user's configuration asked for a terminal description which was not the default screen. This was eventually fixed by an update from Apple. In the version cited in the question, Apple did not provide that terminal description. They do now (and have since 2015). For the record, here is a directory listing showing the related entries for MacPorts (in /opt/local), a locally built ncurses (in /usr/local) and the Apple/system files in /usr/share:

You may notice a few details:

• on OSX, the default file-system ignores case, so the s is encoded in hexadecimal (to make it distinct from S)

• the entries have slightly different sizes. Apple provided an older version of the terminal database, which lacks some features.

• Using toe, I see this:

    --> /usr/local/ncurses/share/terminfo
    ----> /usr/share/terminfo
    ------> /opt/local/share/terminfo

and comparing the system versus MacPorts:
