Screen-5.0.1

Introduction to Screen

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.

Installation of Screen

Fix an issue causing the info page to fail to build: 

sed 's/\([a-z]\)@opensuse/\1@@opensuse/' -i doc/screen.texinfo

Install Screen by running the following commands: 

./configure --prefix=/usr                   \
            --infodir=/usr/share/info       \
            --mandir=/usr/share/man         \
            --disable-pam                   \
            --enable-socket-dir=/run/screen \
            --with-pty-group=5              \
            --with-system_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

Command Explanations

--disable-pam: This option removes a build dependency on Linux-PAM. Remove this option if you want PAM support.

--enable-socket-dir=/run/screen: This option places the per-user sockets in a standard location.

--with-system_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.
