expect : creating a folder with a timestamp in a send command

Hello,

I'm working on an AIX 5.3 mainframe. I have to automatically send files with sftp.

I choose the expect way, here is my code :

Code:

#!/usr/bin/expect -d -f

#spawn /usr/bin/sftp -b sftpbatch user@host

#set mydate `date +%Y%m%d%H%M%S`

cd /imxapp4/impr_files/pcltosend

spawn /usr/bin/sftp user@host

match_max 100000

expect "*ass*"

send -- "mypassword\n"

expect "*Connected*"

send -- "lcd /test\n"

sleep 1

send -- "mkdir date +%Y%m%d%H%M%S\n"

sleep 1

send -- "PUT *\n"

expect eof

output result for the mkdir part :
send: sending "mkdir date +%Y%m%d%H%M%S\n" to { exp4 }

This is simply creating a "date" folder :(

You can see my first attempt :

Code:

#set my_command `date +%Y%m%d%H%M%S`

...

send -- "mkdir mydate\n"

output :
...
executing commands from command file ./test_expect.sh
wrong # args: should be "set varName ?newValue?"
while executing
"set mydate `date +%Y%m%d%H%M%S`"
(file "./test_expect.sh" line 3)

Do you have an idea how I can do this ? With another shell script without the expect stuff it is working as expected ?

Thanks in advance,

Greg.

Something like this?

Code:

#!/usr/local/bin/bash



MYDATE=$(date +%Y%m%d%H%M%S)



expect -f - $MYDATE <<"DONE"

set mydate [lrange $argv 0 0]

spawn /usr/bin/sftp user@localhost

match_max 100000

expect "*ass*"

send -- "passvoid\n"

expect "*Connected*"

send -- "cd /tmp\n"

sleep 1

send -- "mkdir date-$mydate\n"

sleep 1

send -- "QUIT\n"

expect eof

DONE

Hi,

Thanks for your help.

I don't have bash shell installed I think :

Current available shells:
/bin/sh
/bin/bsh
/bin/csh
/bin/ksh
/bin/tsh
/bin/ksh93
/usr/bin/sh
/usr/bin/bsh
/usr/bin/csh
/usr/bin/ksh
/usr/bin/tsh
/usr/bin/ksh93
/usr/bin/rksh
/usr/bin/rksh93
/usr/sbin/uucp/uucico
/usr/sbin/sliplogin
/usr/sbin/snappd

I replaced the first line with #!/usr/bin/bsh
Then I have this :

./sftp_send.sh: syntax error at line 3: `MYDATE=$' unexpected

?

It should work with the default AIX shell (/bin/sh)

Hi thanks you a lot this made my day :)

Just one more thing, do you know how I can log the expect stuff in a file ?
I need a logfile to proof I've uploaded the files :)

With redirection?

Code:

#!/bin/sh



MYDATE=$(date +%Y%m%d%H%M%S)



exec >/tmp/ftp.$MYDATE.log 2>&1



expect -f - $MYDATE <<"DONE"

...

then later:

Code:

$ cat /tmp/ftp.20130829122051.log 

spawn /usr/bin/sftp user@localhost

user@localhost's password: 

Connected to localhost.

cd /tmp

sftp> cd /tmp

sftp> mkdir date-20130829122051

sftp> QUIT

Thank you again it is perfect :)
