SPECIFIC REMOVALS

To remove every file in 
the folder that is not 
dated March:

rm ` ls -al | grep -v "Mar" | awk '{print $9}'` 

Or a specific date in March:

rm ` ls -al | grep -v "Mar 28" | awk '{print $9}'` 

Note: that this is a 
dangerous command to issue 
since it assumes that you 
are consciously using it 
on a directory which is 
full of files that are out 
of date or not belonging to
March or whatever. 

(If this is not the case you 
might get some undesirable 
results.) 

The other thing is that you 
might want to keep more than 
one month's worth of files. 
You would then need to move 
the files from the other month 
out into a temporary subfolder 
while you "clean" the top 
folder.  Then move them back 
in. Also, note that you have 
two types of single quote, 
the first and last are from 
the key under the escape key 
and the one that is used to 
delimit the awk print 
statement is the one next to 
the hash key. I have used this
command myself regularly with a 
few extra pipes (to do certain
specific things which are 
irrelevant here) in order to 
clean out subdirectories where 
the df is running at 100%! 
This has been a time-saver 
when I have had to log on to 
different servers around the 
world and do a regular purge.
