Hi Paul!
Thank you for your quick response!
You were logged in as a normal user.
I was logged in as root.
I tried as normal user and it worked the same as you.
However, logged in as root and the error occurred as before.
Did a search for 'cp -I' and found it for root:
address@hidden ~]# find /root -type f -print |xargs grep -Hn "cp i"
/root/.bashrc:6:alias cp='cp -i'
/root/.cshrc:6:alias cp 'cp -i'
/root/.tcshrc:6:alias cp 'cp -i'
address@hidden ~]# find /etc -type f -print |xargs grep -Hn "cp i"
address@hidden ~]# find /home/mike -type f -print |xargs grep -Hn "cp i"
/home/mike/dpdk-1.7.1/examples/vhost/main.c:2456:
"mbuf_destroy_zcp is: %d\n",
/home/mike/dpdk-1.7.1/examples/vhost/main.c:2474:
"mbuf_destroy_zcp is: %d\n",
/home/mike/dpdk-1.7.1/examples/vhost/main.c:2478:
"mbuf_destroy_zcp is : %d\n",
/home/mike/dpdk/examples/vhost/main.c:2456: "mbuf_destroy_zcp is:
%d\n",
/home/mike/dpdk/examples/vhost/main.c:2474: "mbuf_destroy_zcp is:
%d\n",
/home/mike/dpdk/examples/vhost/main.c:2478: "mbuf_destroy_zcp is :
%d\n",
But there is still an error for interactive:
address@hidden src]# cp -f -r dpdk-1.7.1/* dpdk/
cp: overwrite âdpdk/app/test/test_lpm6.câ? y
cp: overwrite âdpdk/app/test/test_rwlock.câ? y
cp: overwrite âdpdk/app/test/test_table_ports.hâ? y
cp: overwrite âdpdk/app/test/test_logs.câ? y
cp: overwrite âdpdk/app/test/test_pmd_ring.câ? y
cp: overwrite âdpdk/app/test/test_table_tables.hâ?
cp: overwrite âdpdk/app/test/test_lpm.câ?
cp: overwrite âdpdk/app/test/test_malloc.câ?
cp: overwrite âdpdk/app/test/test_errno.câ? y
cp: overwrite âdpdk/app/test/test_hash.câ?
cp: overwrite âdpdk/app/test/test_table_acl.hâ? y
Didn't answer yes or no for some of these and they moved on anyway, indicating
the interactive mode is not operating as expected.
It is a good idea as root not to be overwriting files, so I can understand the
"cp -i" usage for root.
However, some of the reason for using root is to do something that you may not
be able to do as a normal user. So being able to override the -i with a -f
would be highly desirable.
Mike

I do not observe the symptoms that you report. See below. My guess is that
you've aliased 'cp' to 'cp -i', which is probably a mistake.
