There is a Directory...Master(say)

under this there are further sub-directories...
(say) A B C D E,etc

These sub-directories contains files in the format somestring_20070502{yyyymmdd}format.dat.

I want to delete files of month's SMARTLY w/o getting into each sub-directory.

Note Each each day i receive files in the sub-folders, eveyr month i need to delete the files manually.
Can you help me in writing the script(or smart one-liners will also do) to ease the tasks...!!!

Cheers

Which ones exactly do you want to delete? Only those for a specific date? Would this not do what you require?

find . -name \*.dat -atime +30 -print | xargs rm

rm /Master/?/*_20070502.dat is not working...

under Master I want to delete all files *.20070502.dat from all sub-folders.

Change the _ to a . then??

I'm presuming /Master is off the root directory. If not, then obviously you will need to supply the correct path, or cd into it first and just use rm ?/*.20070502.dat.

I'm also presuming that the directories under Master have just single-letter names. If not, replace ? with *.

/home/users/Master - under this there are 5 sub-directories which contains
string_yyyymmdd.dat files

I want to remove the yyymmdd files from all sub-directores..

above is still not working....

You are contradicting yourself. On your previous post you said *.20070502.dat, but now you are saying *_20050702.dat. Are you sure which one is correct?

Presuming it is _, This should work:
