How can I delete all lines before a specific string from a number of files

Question

I have n files, like:

file1:

1aaa
2eee

Test        XXX
Hanna
Lars 

file2:

1fff
2ffffd
3zzz

Test        XXX
Mike
Charly         


        

Answer 1

This will work for your examples and even if the matched pattern is on the very first line:

sed -n -E -e '/Text XXX/,$ p' input.txt | sed '1 d'

For example if you input is simply

Test        XXX
Mike
Charly

This will give you

Mike
Charly

If you want to keep the first match Test XXX then just use:

sed -n -E -e '/Text XXX/,$ p' input.txt
