I have logname command give me this output [EMAIL PROTECTED] ~]$ logname bhaskerv
and say i execute this command [EMAIL PROTECTED] ~]$ echo `logname` bhaskerv till this it is all fine BUT [EMAIL PROTECTED] ~]$ who | grep `logname` logname: no login name Usage: grep [OPTION]... PATTERN [FILE]... Try `grep --help' for more information. is there anything i am doing wrong ?
