Is there a command to show the directory or file name when using
cat to display the contents of files?
For example: assume two files
f2.txt are in
Then when I do
cat ./tmp/*.txt, only the content of the files will be shown. But how to first show the file name, then the content? e.g.:
(The needed command): ./tmp/f1.txt: This is from f1.txt and so on ./tmp/f2.txt: This is from f2.txt ...
Is there a command to do it? (There seems to be no option for
cat to show the file names.)
