Remove Numbers from file

Shell Programming and Scripting
1

I have a file that has some text that looks like this

Some Text
1. More text
2. Different text
Final Text

I would like the remove the lines of text that start with the numbers.

Some Text
Final Text

I have tried to use cat file.txt | grep -Ev 1. > file2.txt
However it just removes lines from the file.

Thank you

Try:

awk ' $1+0 == 0 ' input-file-name >new-file-name

Will remove any line that starts with a number other than zero.

cat some .txt
------
text begin

  1. algo
  2. otro
  3. algo mas
    text end

------
sed -i 's/^[0-9].*$//g' some.txt |awk NF -

----
cat some.txt

text begin
text end
----------------
simple and practical
