I have the question that:
I have a directory in Linux, call it: test_directory.
This directory has files and sub-directories. (only text files)
Text file CAN contains the specific string, for example, MY_STRING_1
For example, one line in one text file maybe:
MY_STRING_1 abc xyz blah blah //MY_STRING_1 is not single word in one line.
Now, I want to access ALL files in this directory (include sub-directories) and after each MY_STRING_1, add MY_STRING_2 as new line.
will becomeCode:MY_STRING_1 blah blah blah abc xyz
Please give me a help. I am using Linux environmentCode:MY_STRING_1 blah blah blah MY_STRING_2 abc xyz
