Remove line of text from multiple files in Linux

Question

Is there a simple way to remove the same line of text from a folder full of text documents at the command line?

Answer 1

If your version of sed allows the -i.bak flag (edit in place):

sed -i.bak '/line of text/d' * 

If not, simply put it in a bash loop:

for file in *.txt
do
    sed '/line of text/d' "$file" > "$file".new_file.txt
done
