[20260604]建立完善linesize.sql脚本.txt

--//删除原来建立的linesize.sql脚本，使用我写的脚本，更加科学简单。

$ cat linesize.sql
-- linesize.sql
--
-- mycpid must be defined before - e.g. in logon.sql
--
-- set linesize according to stty
-- handle with care, as stty is not consistent over platform boundaries
--

set termout off

define _linesize_cmd1 = 'echo -n "set linesize " > /tmp/linesize.sql '
-- for solaris:
-- define _linesize_cmd2 = 'stty -a | awk -F''[ ;]'' ''/columns/ { print $7 }'' >>/tmp/linesize_&mycpid..sql'
-- for linux:
-- define _linesize_cmd2 = 'stty -a | awk -F''[ ;]'' ''/columns/ { print $9 }'' >>/tmp/linesize.sql'
define _linesize_cmd2 = 'stty size | cut -d" " -f2 >>/tmp/linesize.sql'

HOST &_linesize_cmd1
HOST &_linesize_cmd2

@ '/tmp/linesize.sql'

undef _linesize_cmd1 _linesize_cmd2

set termout on

--//新版本如下：

$ cat linesize.sql
-- set linesize according to stty size or tput cols
-- host echo set linesize $(stty size | cut -d" " -f2) > /tmp/linesize.sql
host echo set linesize $(tput cols) |tee /tmp/linesize.sql
@ /tmp/linesize.sql
