GNU sed has the following extension:
-i[SUFFIX], --in-place[=SUFFIX]
edit files in place (makes backup if extension supplied)
If you use that option, you can pass multiple filenames, and sed will
process each one separately, e.g.:
sed -i -e 's/old/new/g' *.txt
Without the -i script, the source files will be concatenated and
processed as a single stream.
If you don't have GNU sed, you need a loop, e.g.:
for file in *.txt ; do
sed 's/.../.../g' "$file" > "$file".tmp && mv -f "$file".tmp "$file"
done
