  Start
  abcd
  efgh
  hijk
  lmn
  

• Second_File.txt

  opq
  rst
  uvw
  xyz

I want to grep all the line between patterns START & END even END pattern in next file

Output should be like:

abcd
efgh
hijk
lmn
opq
rst
uvw
xyz

Solution 1

Try:

$ cat file1 file2 | awk '/pattern1/,/pattern2/'

Solution 2

Using sed Version:

sed -n '/start pattern/,/end pattern/p' file1 file2

For Saving Output To New File

sed -n '/start pattern/,/end pattern/p' file1 file2 > output

Which will create for you new file called output include the desired result.

what if there's Start string in Second_File.txt ?

you need to add what you tried to solve.. anyway, you'll find an answer here (stackoverflow.com/questions/38972736/… - wasn't able to find similar here).. as far as I know, matching across files is default behavior with sed/awk

no start string come again until end string found, its our application logs.
