How to prepend filename to its content without a third file?
Hello,
Is possibly there a way to prepend the filename to its content without a third file? The reason is to add a header to each file contents to distinguish each other when they are pasted side-by-side.
output (with the same name sample.txt):
So far, I've tried:
but got error: input file is output file
I'm aware of the solution is to use a tmp file, and rename it to the original name.
I am wondering if there is a way to do this job without the "tmp" file. The closest function I can think of is to add filename to its content within vim and :wq which does not require a third file name, but I have hundreds of files to modify.
Thanks!
