[SOLVED] SCP with wildcard in Expect

s7upify · 09-27-2010, 03:57 PM

Hey there
I am attempting the copy all the files within a directory using SCP from within an expect routine. I do not want to use recursive directory transfer and am usually able to do this with a wildcard asterisk.

Here's what I am getting:
mach1:~/folder # vi exp7
mach1:~/folder # /root/folder/exp7 passw mach2 /root/folder
spawn scp /root/folder/* root@mach2 :/root/folder/
Password:
/root/folder/*: No such file or directory
Killed by signal 1.

You can see the spawn command I call there. Here it is from vi:
spawn scp $curr_dir/* root@$REMOTEHOST:$curr_dir/

The parameters are correct, so I can narrow the problem down to the wildcard. How do I implement it?

Thanks!

Hi.

To get shell glob'ing working, you'll have to run the command through a shell, rather than getting expect to run the command directly.

Try:
spawn bash -c "spawn scp $curr_dir/* root@$REMOTEHOST:$curr_dir/"
instead. I can't remember off-hand how tcl/expect handles $XXX variables inside quotes, so you might have to mess about with the quoting. Probably not, though.

Thanks Dave it worked like a charm! Just remove the spawn after the -c " (I assume you just copy and pasted :P).

This works:

spawn bash -c "scp $curr_dir/* root@$REMOTEHOST:$curr_dir/"

Not, working for me. I am also stucked in the same issue.

I want to scp these files.

Code:

[root@box1 ~]# ls -lrth /root/*.up
-rw-r--r-- 1 root root  0 Jul 18 21:19 /root/1.up
-rw-r--r-- 1 root root  0 Jul 18 21:19 /root/2.up
-rw-r--r-- 1 root root 29 Jul 18 21:37 /root/last.up

This is how I am using it.

Code:

[root@box1 ~]# cat dev.sh
#!/usr/bin/expect -f
set timeout 20
set files [lindex $argv 0]
set rdir  [lindex $argv 1]
spawn bash -c "scp $files vikas@192.168.1.100:$rdir"
expect "*?assword:*"
send -- "vikas\r"
send -- "\r"
expect eof
[root@box1 ~]#
[root@box1 ~]# ./dev.sh /root/*.up /home/vikas/
spawn bash -c scp /root/1.up vikas@192.168.1.100:/root/2.up
vikas@192.168.1.100's password:
scp: /root/2.up: Permission denied
Killed by signal 1.

However, without a wildcard it works fine.

Code:

[root@box1 ~]# ./dev.sh /root/1.up /home/vikas/
spawn bash -c scp /root/1.up vikas@192.168.1.100:/home/vikas/
vikas@192.168.1.100's password:
1.up                                                                                                                                  100%    0     0.0KB/s   00:00
[root@box1 ~]#

Any ideas people.

Your "/root/*.up" is getting expanded by the shell before it gets into the expect script.

Try:

Code:

./dev.sh '/root/*.up' /home/vikas/

Thanks ilikejam.

This worked for me.

Code:

./dev.sh /root/\*.up /home/vikas/
