I have a file named "test.txt". It contains the following:
Your boss is $ADMIN1
Now, I want to do something like this:
cat test.txt > test2.txt
And achieve something like this when I view the contents of test2.txt:
Your boss is Me
The problem is, it's not that easy to achieve. I don't want to do the "echo Hello $USER1 >> test2.txt" because I'm planning to implement this on a MB-sized text file.
I can't google the right term that's why I explained it right away.
