RE Regular expression

CLUTIER — Tue, 30 Jul 2002 07:12:02 GMT

I really want to use regular expression
like [^.*][Aa][T-U]*.DON in a frecover command
I just give an example in my previous message
I have a lot of file with very long name to restore ex : sgbd.1789.fzh.12.Z.DON
I must use regular expression if I can ????

Hi

As put in your previous question. Forget it.

Make a graph file by reding the index and frecovcr with that.

Sorry for interfering despite lacking knowledge of frecover.
I'm not sure about the regex capabilities of the frecover program.
There is really a mess as far as it comes to regex, because every program that pretends to understand them treats them differently and has its own kind of syntax (that's why I stick to Perl, whenever I want to make extended use of regex).
I fear that you may have to resort to the shell's (i.e. derived from csh) globbing mechanism.
There you have to use the '!' to inverse a character set (another of those idiosyncrasies).

Hi,

as stated before frecover does not support wildcards...
BUT there's always a workaround, not?

frecover -f /dev/rmt/0m -I /tmp/indexfile
-- this creates an index of all files on the backup

grep [whatever] /tmp/indexfile > /tmp/graph
-- select the required files

frecover -your_options -i /tmp/graph

good luck,
Thierry.
