Shell Programming and Scripting

hi..

i am new to here. can anybody tell me how can we change the date format in the 'last' command.

EX- on running last command i am getting --

rruat pts/12 172.18.40.101 Tue May 3 12:59 still logged in
rruat pts/10 blr2-3f-239.asco Tue May 3 12:59 - 13:09 (00:10)

desired output should be

rruat pts/12 172.18.40.101 Tue 05 3 12:59 still logged in
rruat pts/10 blr2-3f-239.asco Tue 05 3 12:59 - 13:09 (00:10)

thanks in advance

Code:

last | awk 'BEGIN{a["Jan"]="01"; a["Feb"]="02"; ...add other months here}NF==10{$5=a[$5]}NF==9{$6=a[$6]} 1'

You will have to modify a little bit the above script to make it work.

hi
thanks or the reply..but my question is- is there any switch avaliable for the last command to change the date format.

actually the real problem is --

file 'temp' contains the data of last command.
now i am reading the file through while loop. and want to display only those lines which have date >= todays' date.
i want to do this by using awk. plese tell if you have any idea on this.

thanks
