Screen is a terminal multiplexor that runs several separate processes, typically interactive shells, on a single physical character-based terminal. Each virtual terminal emulates a DEC VT100 plus several ANSI X3.64 and ISO 2022 functions and also provides configurable input and output translation, serial port support, configurable logging, multi-user support, and many character encodings, including UTF-8. Screen sessions can be detached and resumed later on a different terminal.
This package is known to build and work properly using an LFS-11.0 platform.

First, apply a patch from upstream that fixes a security vulnerability:
patch -Np1 -i ../screen-4.8.0-upstream_fixes-1.patch
Install Screen by running the following commands:
./configure --prefix=/usr \
--infodir=/usr/share/info \
--mandir=/usr/share/man \
--with-socket-dir=/run/screen \
--with-pty-group=5 \
--with-sys-screenrc=/etc/screenrc &&
sed -i -e "s%/usr/local/etc/screenrc%/etc/screenrc%" {etc,doc}/* &&
make
This package does not come with a test suite.
Now, as the root user:
make install && install -m 644 etc/etcscreenrc /etc/screenrc
--with-socket-dir=/run/screen: This
option places the per-user sockets in a standard location.
--with-sys-screenrc=/etc/screenrc:
This option places the global screenrc file in /etc.
--with-pty-group=5: This
option sets the gid to the value used by LFS.
sed -i -e "s%/usr/local/etc/screenrc%/etc/screenrc%" {etc,doc}/*: This command corrects the configuration and documentation files to the location that is used here for the global screenrc file.
