Hi, I need some help with this one.
I'm tryig to execute the following
sed -e 's/string1/string2/g' filename
The script runs ok and prints to stdout but is not saving the changes to the specified filename. Is that a normal behaviour or I'm missing a command parameter.

Thanks in advance, any help apreciated

sed -e 's/string1/string2/g' filename >filename.$$; mv -f filename.$$ filename
Although I agree with the post above about using Perl. Forget sed. You can do anything sed can
do in Perl and even understand it latter. Sed "programs" tend to look like line noise :-).

the above approach has a potential bug of changing the default file permissions of the original file
