I am tring to use xargs -a
to read the contents of a file that has a list of filenames in it.
My directory working in looks like:
backups file1.bak file2.bak file3.bak bakfiles.txt
File name with filenames in it: bakfiles.txt
bakfiles.txt contents:
file1.bak file2.bak file3.bak
So essentially I’m trying to copy file1.bak,file2.bak,file3.bak
into the folder backups
. But using the contents of bakfiles.txt
to do so.
I tried:
xargs -a bakfiles.txt | cp {} backups
But I get the error:
cp: cannot stat `{}': No such file or directory
I should mention i also tried:
xargs -a bakfiles.txt cp {} backups
And get the error:
cp: target `file3.bak' is not a directory
