Wildcard problem with recursion

Wildcard problem with recursion

[Ajith Kumar]

Cygwin utilities like grep or ls with -R options doesn't seem to be working.
egs when I say
>grep -r FLD_DCT_STRING  *.h??
I get
grep: *.hpp: No such file or directory

However there are many .h, .hxx and .hpp files in the subdirectories

ls also gives the same err.

Any solutons?

Regards,
ajith

Yes, read the shell man pages to learn how file completion works.
What you want is a job for `find | xargs grep'.

Thanks for the xargs tip Corinna - thats a new one on me.

an alternative (talking to original poster here) is:

grep FLD_DCT_STRING `find . -name '*.h??'`

Or you can search *directories* recursively with grep, but this doesn't 
allow you to filter the file type. e.g.:

grep -r FLD_DCT_STRING .

where '.' is the current directory - this will search all files in 
subdirectories too. See 'info grep'.

an alternative (talking to original poster here) is:

grep FLD_DCT_STRING `find . -name '*.h??'` ------------------------------ 1

Or you can search *directories* recursively with grep, but this doesn't
allow you to filter the file type. e.g.:

grep -r FLD_DCT_STRING .                   ------------------------------- 2

****************************************************************************
********

The command 2 works fine. However 1 fails revereting to my original problem.
If I execute the find command alone I get

D:\views\aj_pvt\Tally63>find . -name '*.h??'
File not found - '*.h??'

or

D:\views\aj_pvt\Tally63>find . -name *.h??
File not found - *.h??

I did n't reply my previous cygwin installation. As u see I  use the Win2k
cmd prompt

ajith

$ info bash # bash shell info pages (hypertext)
 (some man pages are updated less requently than info pages)
$ info find
$ info xargs

In most cases you can replace "info" with "man" - but note that man pages
often are less frequently updated.

If
	$ type -a <command>
says "Internal command" then
	$ help <command>
usually tells more.

Though you might find it easier to find relevant parts of the text by using
less's "/" key to search for interesting text in the _man_ pages  (this
works in the info pages too, but is less succesful IMO)
