writing files to a dir in round robin order
I have a list of directories. (say a1,a2,a3,a4,a5)
I need to get the directory last modified and access the next one to put some files over there (say if a3 is the latest dir modified ie, last time files were put into a3, this time I need to move the files in a4)...and if a5 is the last modified dir, I need to move the files in a1. thus it works in a round robin manner. Can u pls suggest how do I achieve this ?

try this,

Code:
val=`/usr/bin/ls -1rtF | sed -n "/\/$/p" | sed -n '$p' | sed "s/[A-Za-z/]//g"`
if [ $val eq 5 ]
then
 newval=1
else
 newval = $(($val + 1))
fi
echo "your new dir is a$newval"

not optimised! Smilie

Oops !!! A small mistake on my side :-( ...all these dir names are configurable...instead of a1...a5, they can be anything, (say abc,mnp,xyz) ...so the logic doesn't work...any alternative ?

If not a1 ... a5

how do you maintain the order ?

Like, how do you determine which should go first, next ?

If you maintain the order somewhere ( like that in a configuration file ), we could retrieve based on that.

Could you please provide some more input on that ? Smilie

last_modified_dir=`ls -ltu | grep ^d | awk '{print $NF}' | sed -n 1p`
files_to_be_moved_to=`ls -ltu | grep ^d | awk '{print $NF}' | sed -n 2p`

if you have Python, here's an alternative
Code:
import os,shutil
rootdir = "/home/test"
os.chdir(rootdir)
store={} #store directories' access times
directories = ['a1','a2','a3','a4','a5'] #configure directories here
dirchange = { 'a1' : 'a2' , 'a2':'a3', 'a3':'a4' , 'a4':'a5','a5':'a1' }
for d in directories:
    store[os.stat(d)[8] ] = d
latesttime = reversed(sorted(store.keys())).next()
latestdir = store[latesttime]
os.chdir(latestdir)
for file in os.listdir('.'):
    shutil.move(file, os.path.join(rootdir, dirchange[latestdir]))
