osx - Delete line ending with a newline character in text file -

i need delete same line in large number of text files. have been trying use sed, cannot delete newline character @ end. following deletes line, not newline:

sed -i -e 's/version:1//' *.txt 

i have tried using following delete newline also, not work:

sed -i -e 's/version:1\n//' *.txt 

is there anyway specify newline in sed substitute command or there other command line tool can use achieve goal? thank you

you can use sed command:

sed -i -e '/version:1/d' 

for this.

the following transcript gives example:

pax> echo 'hello > goodbye > hello again' | sed '/oo/d' hello hello again 

you should check whether want match whole lines with, example:

sed -i -e '/^version:1$/d' 

since, stands, delete lines following:

version:10 conversion:1
