st - simple terminal
|
||||
--------------------
|
||||
st is a simple terminal emulator for X which sucks less.
|
||||
|
||||
|
||||
Requirements
|
||||
------------
|
||||
In order to build st you need the Xlib header files.
|
||||
|
||||
|
||||
Installation
|
||||
------------
|
||||
Edit config.mk to match your local setup (st is installed into
|
||||
the /usr/local namespace by default).
|
||||
|
||||
Afterwards enter the following command to build and install st (if
|
||||
necessary as root):
|
||||
|
||||
make clean install
|
||||
|
||||
|
||||
Running st
|
||||
----------
|
||||
If you did not install st with make clean install, you must compile
|
||||
the st terminfo entry with the following command:
|
||||
|
||||
tic -sx st.info
|
||||
|
||||
See the man page for additional details.
