the history command expects a numeric argument with it. is it possible to find out the history o commands of a particular user say John_smith for example?

Code:
# ./justdoit test
test USER ".sh_history" HISTORY FILE(s)
=========================================
     1  /bin/bash
     2  bash
     3  exit
     4  ls -l bash
     5  ls -l /bin/bash
     6  exit
     7  bash
     8  exit
     9  bash
    10  exit


Code:
#!/bin/bash
## justdoit simple users history view script unix.com @ygemici
user=$1
for i in `find "/home/$user" -name "*history" 2>/dev/null`
do
 echo $i|sed 's|.*/\(.*\)/.*$|\1 USER "'$(echo "${i##/*/}")'" HISTORY FILE(s)|'
 echo "=========================================";sleep 1
 strings -a $i|cat -n|more -d;echo;sleep 2
done

Tcl_RecordAndEvalObj(3) 				      Tcl Library Procedures					   Tcl_RecordAndEvalObj(3)

__________________________________________________________________________________________________________________________________________________

NAME

       Tcl_RecordAndEvalObj - save command on history list before evaluating

SYNOPSIS

       #include <tcl.h>

       int
       Tcl_RecordAndEvalObj(interp, cmdPtr, flags)

ARGUMENTS

       Tcl_Interp   *interp    (in)	 Tcl interpreter in which to evaluate command.

       Tcl_Obj	    *cmdPtr    (in)	 Points to a Tcl object containing a command (or sequence of commands) to execute.

       int	    flags      (in)	 An  OR'ed  combination  of  flag  bits.   TCL_NO_EVAL	means  record  the  command but don't evaluate it.
					 TCL_EVAL_GLOBAL means evaluate the command at global level instead of the current stack level.
_________________________________________________________________

DESCRIPTION

       Tcl_RecordAndEvalObj is invoked to record a command as an event on the history list and then execute it using Tcl_EvalObjEx (or Tcl_Global-
       EvalObj	if  the  TCL_EVAL_GLOBAL  bit is set in flags).  It returns a completion code such as TCL_OK just like Tcl_EvalObjEx, as well as a
       result object containing additional information (a result value or error message) that can be retrieved	using  Tcl_GetObjResult.   If  you
       don't  want  the  command  recorded  on	the  history  list then you should invoke Tcl_EvalObjEx instead of Tcl_RecordAndEvalObj.  Normally
       Tcl_RecordAndEvalObj is only called with top-level commands typed by the user, since the purpose of history is to allow	the  user  to  re-
       issue recently-invoked commands.  If the flags argument contains the TCL_NO_EVAL bit then the command is recorded without being evaluated.
