Imagine my directory looked like this:
./original.txt
./blah.1.txt
./blah.2.txt
[...]
./blah.999999.txt
I essentially want to replace every blah.* file with the contents of original. My initial try was to do this:
$ cp original.txt blah.*
But I get:
cp: target ``blah.1.txt' is not a directory
Just one more option with tee:
cat original.txt | tee blah.*
And here's a test case that you can try at home under supervision from a responsible adult:
$ echo "rawr" | tee blah.{1..99}.txt
rawr
$ ls
