Environment Variables If it is set and long names are enabled, it overrides the width specified in the file for all system and conforming applications that write formatted output. RETURN VALUE
exits with one of the following values: Successful completion Failure DIAGNOSTICS
You may have attempted to use the option for a second time. You tried to use the option before using the option. A call to the function failed. WARNINGS
The file is the switch that marks a long name system. If it is missing, short names are assumed and the variable is ignored. While many programs are unaffected by long names in a short name environment, some may behave abnormally and some may abort. It is recommended that you do not attempt to restore the short name environment once long names have been enabled. Do not use the system constant with the command or the function to test for name length; it is not changed when long names are enabled. AUTHOR
was developed by HP. FILES
If this file is present, the system is enabled for long user and group names; otherwise, it is not. This file contains the default display width, as set with the option. SEE ALSO
