On Windows and UNIX systems, command history is stored in a file named logdump.hst. On NonStop systems, command history is stored in a file named logduhst. The file is created in the home location of the user who first started Logdump.
When Logdump starts up, it looks for the history file in one of the following locations, depending on the platform:
The USERPROFILE environment variable.
The $HOME environment variable.
The default $vol.subvol.
If the file exists, Logdump loads the command history into a buffer. The command history buffer holds 400 commands. Upon termination of the Logdump session, the session's history is appended to the file.
