Concatenate multiple files but include filename as section headers
Was looking for the same thing, and found this to suggest:
tail -n +1 file1.txt file2.txt file3.txtOutput:
==> file1.txt <==<contents of file1.txt>==> file2.txt <==<contents of file2.txt>==> file3.txt <==<contents of file3.txt>If there is only a single file then the header will not be printed. If using GNU utils, you can use -v to always print a header.
I used grep for something similar:
grep "" *.txtIt does not give you a 'header', but prefixes every line with the filename.
This should do the trick as well:
find . -type f -print -exec cat {} \;Means:
find = linux `find` command finds filenames, see `man find` for more info. = in current directory-type f = only files, not directories-print = show found file-exec = additionally execute another linux commandcat = linux `cat` command, see `man cat`, displays file contents{} = placeholder for the currently found filename\; = tell `find` command that it ends now hereYou further can combine searches trough boolean operators like -and or -or. find -ls is nice, too.
