unix sed
 

what is wrong with this command:
sed -e 's/dog/cat/g' 1.html

I want to replace "dog" for "cat everywhere in the 1.html file

I get an output of the desired result to the screen and not to the file

ok

than change it to this:
sed -e 's/cat/dog/g' 1.html

isnt that the same as what you typed?
I usually do
sed -e 's/cat/dog/g' 1.html > 1.html.tmp && cp -f 1.html.tmp > 1.html && rm -f 1.html.tmp

ok that works
but isn't there a way to do it with the temporarly file?

sed is your friend. as is awk. ( or perl :) )
