shell - Remove duplicate records in history file of KSH -


how can set in ksh's .kshrc duplicate records in history file deleted after every command?

thanks

ksh93 has never supported option rewrite history.

some shells write history file on exit, or on request. ksh93 writes after every command, generate lots of synchronous i/o.

in environments (e.g., nfs) affect interactive experience, causing shell wait after each command.
