Linux commands to copy one file to many files

linux cp

Does

cp file1 file2 ; cp file1 file3

count as a "one-line command/script"? How about

for file in file2 file3 ; do cp file1 "$file" ; done

Or, for a slightly looser sense of "copy":

tee <file1 file2 file3 >/dev/null

linux cp

just for fun, if you need a big list of files:
tee <sourcefile.jpg targetfiles{01-50}.jpg >/dev/null- Kelvin Feb 12 at 19:52

But there's a little typo. Should be:

tee <sourcefile.jpg targetfiles{01..50}.jpg >/dev/null

And as mentioned above, that doesn't copy permissions.

linux cp

You can improve/simplify the for approach (answered by @ruakh) of copying by using ranges from bash brace expansion:

for f in file{1..10}; do cp file $f; done

This copies file into file1, file2, ..., file10.
