Redirecting part of output to stdout

Hi,

I am trying to execute a command like this:

Code:
find ./ -name "*.gz" -exec sh -c 'zcat {} | awk -f parse.awk' \; >> output

If I want to print the filename, i generally use the -print argument to the find command but when I am redirecting the output to a file, how can I print just the filenames into stdout with the rest of the output into the file? Any help is much appreciated.

EDIT: Ah... Figured out... Sorry... Here's the solution:

Code:
find ./ -name "*.gz" -exec sh -c 'zcat {} | awk -f parse.awk >> output' \;

The solution was to put the redirection inside the exec itself...

FIND(1) 						      General Commands Manual							   FIND(1)

NAME
find - find files meeting a given condition SYNOPSIS
find directory expression EXAMPLES
find / -name a.out -print # Print all a.out paths find /usr/ast ! -newer f -ok rm {} ; # Ask before removing find /usr -size +20 -exec mv {} /big ; # move files > 20 blks find / -name a.out -o -name '*.o' -exec rm {}; # 2 conds DESCRIPTION
Find descends the file tree starting at the given directory checking each file in that directory and its subdirectories against a predi- cate. If the predicate is true, an action is taken. The predicates may be connected by -a (Boolean and), -o (Boolean or) and ! (Boolean negation). Each predicate is true under the conditions specified below. The integer n may also be +n to mean any value greater than n, -n to mean any value less than n, or just n for exactly n. -name s true if current filename is s (include shell wild cards) -size n true if file size is n blocks -inum n true if the current file's i-node number is n -mtime ntrue if modification time relative to today (in days) is n -links ntrue if the number of links to the file is n -newer ftrue if the file is newer than f -perm n true if the file's permission bits = n (n is in octal) -user u true if the uid = u (a numerical value, not a login name) -group gtrue if the gid = g (a numerical value, not a group name) -type x where x is bcdfug (block, char, dir, regular file, setuid, setgid) -xdev do not cross devices to search mounted file systems Following the expression can be one of the following, telling what to do when a file is found: -print print the file name on standard output -exec execute a MINIX command, {} stands for the file name -ok prompts before executing the command SEE ALSO
