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

To find a pattern and remove the line containing the pattern below command can be used

find . -name "*" -type f | xargs sed -i -e '//d'

Example : if you want to remove the line containing word sleep in all the xml files

find . -name "*.xml" -type f | xargs sed -i -e '/sleep/d'

NOTE : Be careful before choosing a pattern as it will delete the line recursively in all the files in the current directory hierarchy :)
