Hi,
I need to access a user's command history. However, the dilemma is that he is logged in and so his current history is not yet flushed to .bash_history file which gets flushed when he logs out. Is there a way I can still access his most recent history?

EXPAND(1) BSD General Commands Manual EXPAND(1)
NAME
expand, unexpand -- expand tabs to spaces, and vice versa
SYNOPSIS
expand [-t tab1,tab2,...,tabn] [file ...]
unexpand [-a | -t tab1,tab2,...,tabn] [file ...]
DESCRIPTION
The expand utility processes the named files or the standard input writing the standard output with tabs changed into blanks. Backspace
characters are preserved into the output and decrement the column count for tab calculations. The expand utility is useful for pre-process-
ing character files (before sorting, looking at specific columns, etc.) that contain tabs.
The unexpand utility puts tabs back into the data from the standard input or the named files and writes the result on the standard output.
The following options are available:
-a (unexpand only.) By default, only leading blanks and tabs are reconverted to maximal strings of tabs. If the -a option is given,
then tabs are inserted whenever they would compress the resultant file by replacing two or more characters.
-t tab1,tab2,...,tabn
Set tab stops at column positions tab1, tab2, ..., tabn. If only a single number is given, tab stops are set that number of column
positions apart instead of the default number of 8.
ENVIRONMENT
The LANG, LC_ALL and LC_CTYPE environment variables affect the execution of expand and unexpand as described in environ(7).
EXIT STATUS
The expand and unexpand utilities exit 0 on success, and >0 if an error occurs.
STANDARDS
The expand and unexpand utilities conform to IEEE Std 1003.1-2001 (``POSIX.1'').
HISTORY
The expand command appeared in 3.0BSD.
