How to set a variable date in a script file ?

[zoby]

With a script file, I would like to extract day by day some lines from a file which have been added day by day. The format of these lines are :

...
root pts/17 10.81.0.58 Tue Feb 13 09:20 - 09:21 (00:01)
...

So in this file I would like all the lines which the date : Tue Feb 13.

How can I do that ? I know the grep command to extract but what are the arguments to extract only the date I would like? Thanks for helping me.

Hi, zoby!

To extract lines which date is 'Tue Feb 13', use this awk command:

awk '/Tue Feb 13/' file

You can redirect output to newfile:

awk '/Tue Feb 13/' file > newfile

For this kind of problems, awk is an excellent solution.

Hi Krunek,

Yes I 've just tested it and it works but instead of setting the date 'Tue Feb 13' with the awk command, is there a variable for the date which generate day by day the date of the day whitout change the script file all the days ?
Sorry if my english is not well-understanding
