that is one way to do it. Thanks.

But just out of curiosity, why does the grep -v not find not work?

if we do

Code:
ls -ltr | grep -v find

then all the files containing find will not be shown.

If we do

Code:
find / -name 'filename' | grep -v find

then I would expect all lines returned with "find" on them being filtered out.

Why does this not happen?

Thanks.

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
