Question

Unix script to parse file name out of text file

Asked by: kkatula

I have a text file that looks like this:

-rw-r--r--    1 10110    105          5601 Sep 09 08:04 20090908.txt
-rw-r--r--    1 10110    105         62640 Sep 09 21:00 44734868.pdf
-rw-r--r--    1 10110    105         78639 Sep 09 21:15 44801530.pdf
drwxrwsr-x    2 10110    105         24576 Sep 10 08:05 .
-rw-r--r--    1 10110    105          5082 Sep 10 08:05 20090909.txt

I need to be able to query this file and get the name of any .txt file that has today's date on it.  So on September 10th, I need to be able to run this script and the only output will be 20090909.txt which has a file modification date of Sep 10.  Any ideas?

Try this:

grep "`date '+ %b %d '`" input | awk '{print $9}'

You should cut & paste that - there are spaces after the "+" and after the "%d" that are important. ;-)

$ grep "`date '+ %b %d '`" ucclist.txt | awk '{print $9}'
$

When I run that, I do not get any results where ucclist.txt is the name of the .txt file.
$ tail ucclist.txt

There's no file with today's date in ucclist.dat, I assume (today is Sep 11)!

 

by: nemws1Posted on 2009-09-11 at 07:39:33ID: 25309964

I had assumed you provided just the top of your file and that there would be entries from today in it eventually. ;-)

I see now that you're 'tail'ing it - so there are no entries for today (yet?).

You are correct.  It works great!

Thanks,
