Re: History not working in root user

Re: History not working in root user

Hi,

Does history file(/.sh_history) exist?
#ll /.sh_history

What is the output of #echo $HISTFILE?

root user .profile should contain this.
# grep HISTFILE /.profile
HISTFILE=/.sh_history
export HISTFILE PS1
#
Best wishes,

Ganesh.

Re: History not working in root user

Hi,

Look at the time stamp of .sh_history file.
It is last modified on sept 18 2008.

# ll .sh_history
-rw------- 1 root sys 1042 Sep 18 2008 .sh_history


So some modifications has been done on root's .profile which is pointing to some other history file.

Could you provide the following outputs?

#echo $HISTFILE
#grep HISTFILE /.profile
Best wishes,

Ganesh.

Re: History not working in root user

Jestin,

remove your .sh_history file it could be corrupted.

# echo $SHELL

if /sbin/sh then

# HISTFILE=/.sh_history
# HISTSIZE=2048
# EDITOR=vi
# export HISTFILE HISTSIZE EDITOR

check if the new sh_history is updated.

Robert-Jan
