Question

Can somebody give me an example how I can copy a file and open the copied file afterwards with the “cat” command in Linux? The statement should be in one line.

Thanks for your help!

Answer 1

You can cheat:

cat inputfile > outputfile && cat outputfile

You can substitute the first part using cp:

cp inputfile outputfile && cat outputfile

You can use ; instead of &&, so that the outputfile is displayed even if the copying did not succeed:

cp inputfile outputfile; cat outputfile

Or you can use tee:

cat inputfile | tee outputfile (note that this displays the file while copying, not afterwards)
