THx Guys,

In the mean time I have written one script which will give me the users last login in the system ( All users )
Code:
# !/usr/bin/bash

ssh unadm@$1 ' lsuser -a time_last_login ALL | sed 's/\ time_last_login=/:/g' > /userlogins

cat userlogins | grep : > temp | awk -F":" '{print $2}' temp | xargs -I {} perl -le "print scalar localtime ({})" > temp1
awk -F":" '{print $1}' temp > temp2
paste temp2 temp1
rm temp temp1 temp2

In the above I want to execute the first line command highlighted below as root using sudo..

ssh unadm@$1 ' lsuser -a time_last_login ALL | sed 's/\ time_last_login=/:/g' > /userlogins


Can anyone explain how can i use sudo in this remote command

NAME
last - Displays information about previous logins SYNOPSIS
/usr/bin/last [-n maxlines | -maxlines] [-f filename] [name...] [tty...] FLAGS
Reads information about previous logins from filename instead of from the accounting file /var/adm/wtmp. Limits the output to maxlines number of record lines. Limits the output to maxlines number of record lines. Provides SVID conformance, and is equivalent to -maxlines. DESCRIPTION
The last command displays, in reverse chronological order, all previous logins and logouts entered in the currently active /var/adm/wtmp file. The list of output records can be restricted to maxlines number of record lines if the -maxlines or the -n maxlines flag is speci- fied. The last command also displays logins and logouts by the user specified with the name parameter, and logins and logouts from termi- nals specified with the tty parameter. The tty terminal references can be fully named (for example, tty0) or abbreviated (for example, 0). For each process, the following information is displayed according to session, with the most recent session listed first: Time session began Duration of session The tty terminal on which session took place The following information is included when applicable: Terminations when rebooting Continuing sessions If the last command is interrupted, an indication of how far the search has progressed in the /var/adm/wtmp file is provided. If the com- mand is interrupted by a quit signal, an indication as to how far the search has progressed is provided, but the search continues. To obtain information about the mean time between reboots, use the word shutdown as the name parameter. EXAMPLES
The following example displays all recorded logins and logouts for user root and all recorded logins and logouts from the console terminal: last root console The following example displays the time between system reboots: % last shutdown shutdown ~ Fri Aug 28 17:59 shutdown ~ Mon Aug 17 09:07 wtmp begins Mon Aug 17 08:51 In the previous example, the shutdown pseudouser is used to list the mean time between system reboots. FILES
Specifies the command path. Header file defining structures used to organize login information. The login/logout database file. RELATED INFORMATION
