[SOLVED] bash: how to replace symbols inside the file with filename

hi
the question is how to replace some symbols (for example @@@) inside of the group of files with its filenames?
i supposed that it should be something like this:

for i in *
do sed 's/^@@@=.*/$i/g' $i
done

but such a cycle writes just symbols "$i" not the filename.
is such a solving possible in general without making any complicated scripts?

If you are trying to use a bash variable with sed, and that is your problem, use double quotes instead of single quotes.

E.g.

Code:

search=foo
replace=bar
target=baz.txt
sed -i "s/$search/$replace/" $target

Will work as expected.
