setenv - Set environment
setenv [ -u user ]
Use setenv to bring up an interactive menu of options allowing you to define various environmental preferences for your sessions online. Setenv updates your current settings, and will also store them for future sessions. Each time you log onto the system your environment is initialized as defined.
Options that you can modify:
o Cancel key
o Null delays after newlines
o Tabs: preserved or expanded
o Terminal height in lines
o Terminal width in columns
o Terminal to emulate
o Menu mode, or just prompts
o Single-key input mode: on or off
o Choice of text editor (standard or visual)
The -u option allows the super user to specify a different user.
