Uh, whatever. These days, Perl is a standard Unix tool. 

|A better approach to the original question would be:
|
|  for i in *.c *.h; do 
|    sed <$i 's/word1/word2/g' >$i.bak; 
|    mv $i.bak $i; 
|  done

IMHO, the Perl one-liner is concise and practical.

To be perfectly clear... this one-liner is equivalent to
Greg's shell snippet,

	% perl -i.bak -pe 's/word1/word2/g;' *.[ch]

Seeing more than one way to accomplish the same task
is probably the best way to learn.

To each his own,
Charles
