How to use cp from stdin?

Question

Note:

# cat /tmp/foo - regular file

/lib/a.lib
/lib/b.lib
/lib/c.lib
/lib/d.lib

---

cat /tmp/foo | xargs cp /tmp/fred

cp: target / lib / d.lib is not a directory

Answer 1

xargs usually puts its substituted arguments last. You could just do:

$ cp `cat /tmp/foo` /tmp/fred/.

If these are really just lib files, then it cp /lib/?.lib /tmp/fred/.will work fine.

And in order to do this with xargs, here is an example of entering an argument:

0:~$ (echo word1; echo word2) | xargs -I here echo here how now
word1 how now
word2 how now
0:~$

Assuming it /tmp/fredis a directory, specify it using the -t( --target-directory) parameter :

$ cat /tmp/foo | xargs cp -t /tmp/fred
