Hi.
You mentioned "files.txt" and "100 files". Can you be more specific about from which file(s) the text should be deleted?
(assuming all files in directory...)
bash code:
ls | while read FILE; do
sed -n "/^[a-z0-9.-]\+$/ p" $FILE > FILE.tmp.$$
cp -f $FILE.tmp.$$ $FILE && rm $FILE.tmp.$$
done
Or
bash code:
ls | while read FILE; do
grep "^[a-z0-9.-]\+$" $FILE > $FILE.tmp.$$
cp -f $FILE.tmp.$$ $FILE && rm $FILE.tmp.$$
done
Edit: Highlight=bash bbcode added by neo .....
