linux - "xargs -a file" to copy files to a folder -

i tring use xargs -a read contents of file has list of filenames in it.

my directory working in looks like:

backups file1.bak file2.bak file3.bak bakfiles.txt

file name filenames in it: bakfiles.txt

bakfiles.txt contents:

file1.bak file2.bak file3.bak

so i'm trying copy file1.bak,file2.bak,file3.bak folder backups. using contents of bakfiles.txt so.

i tried:

xargs -a bakfiles.txt | cp {} backups

but error:

cp: cannot stat `{}': no such file or directory

i should mention tried:

xargs -a bakfiles.txt cp {} backups

and error:

cp: target `file3.bak' not directory

this works me on windows 7 using mks toolkit version of 'xargs'

cat bakfiles.txt | xargs -i '{}' cp '{}' backups/'{}'
