Watch out : since the -prune does not examine any directories or files in the directory structure below the pattern just matched, its position in the command line matter : you may want to put it on first position (at least, it does as far as i have tested on a solaris machine)

Code:
# find t???* -type f -prune
taitai/tutututu
tst2
tstt
tyty/tyty.f
tyty/toutou/toutou.f
tyty/toutou/whatever/whatever.f
# find t???* -prune -type f
tst2
tstt
#

We 've just cross posted, i have updated my previous post you can get a look at it back again Smilie

If Im not mistaken
Code:
 
find ????10??_*.dat -prune -type f -mtime +91

does the same as
Code:
 
find ????10??_*.dat -type f -mtime +91

What I was asking was how to use -prune with
find . -name '????10??_*.dat' -type f -mtime +91 so it would work the same as find ????10??_*.dat -type f -mtime +91

I am using korn on Solaris 10, the man for find doesnt have anything about -maxdepth so it must be bash or another unix flavour command.

No it is not the same, at least, as far as i have tested ... here is a shorter example :
Code:
# find t???* -type f
taitai/tutututu
tst2
tstt
tyty/tyty.f
tyty/toutou/toutou.f
tyty/toutou/whatever/whatever.f

Code:
# find t???* -prune -type f
tst2
tstt
#

See : with the -prune, it didn't displayed the taitai nor tyty directories

Just give a try to the suggestion i did in post #6 and let me know

Maybe something like...
Code:
find . \( ! -name . -type d  -prune \) -o -name '????10??_*.dat' -type f -mtime +91 -print

Or just

Code:
find ./????10??_*.dat -prune -mtime +91

All depends whether the directory matching the pattern are wanted or not.

Since the -type f option was initially used by stumpy1, i assumed the directory matching the pattern was not expected.

@Perderabo,

I tested your code with my example (and leaving the -mtime last filter) :

Code:
# find . \( ! -name . -type d  -prune \) -o -name 't???*' -type f
./tst2
./taitai
./tyty
./tstt

So you code also return the directories just like this one would :
Code:
 # find ./t???* -prune
./taitai
./tst2
./tstt
./tyty

Just FYI, the tree i have setup for test purpose was :

Code:
# find . -name 't???*' -type f
./tst2
./taitai/tutututu
./tyty/tyty.f
./tyty/toutou/toutou.f
./tstt

Just to flog a dead horse maybe..
Code:
find . \( ! -name . -type d  -prune \) -o   \( -name '????10??_*.dat' -type f -mtime +91 -print \)

Like you I assume that no directories matching the name are expected to exist. The first -type d is just to control the pruning... prune all directories except for . )

@stumpy

I am not sure to understand what entries you expect or not in your output :

Could you please show us an example of what kind of entries you want to reach and what kind of entries you do not want ?
