I am looking for a bash one-liner which can
cat a number of files with a number of fixed lines.
file1 line 1 file1 line 2
file2 line 1 file2 line 2
Then I am looking for something like
cat-with-strings foo file1.txt bar file2.txt baz
foo file1 line 1 file1 line 2 bar file2 line 1 file2 line 2 baz
How can I do this in a single line of bash, using standard linux tools (sed, awk, cat, etc) and without creating any files to hold
