How to copy files from one file to another file that has contents I want to keep? In other words, I want the contents of file1 to go in file2 but the info in file1 to be added to the existing stuff in file2 ? The format in file2 should ideally have file2 info first then file1. Then I want to add file3 to file2 with the contents in file2 resulting in an output format of 1. File2 contents then 2. File1 contents and lastly file3 contents. All the files are in different directories. I would think a simple cp file1 file2 or cat file1 >> file2 would work but for some odd reason when I view file2 afterwards it only shows file1 info. Thank you in advance.
I think what you are lookig for is to
append which is done using
Let say you have
file1 with the content
file2 with the content
Then you can do:
cat file1 >> file2
This appends content of file1 to the end of file2.
now the result of file2` will be:
I'm file2 I'm file1
You can repeat the same command to add more as many more files as you like to the bottom of a file.
