expect script.
The following packages need to be installed on the SUN server for the expect script. I downloaded the x86packages from sun freeware as I'm running the script from an x86 server.
tcl-8.5.3-sol10-x86-local
libgcc-3.4.6-sol10-x86-local
expect-5.43.0-sol10-x86-local
1)pkgadd -d tcl-8.5.3-sol10-x86-local
2)pkgadd -d libgcc-3.4.6-sol10-x86-local
The following packages are available:
1 SMClgcc346 libgcc
(x86) 3.4.6
Installation of
3)pkgadd -d expect-5.43.0-sol10-x86-local
The following packages are available:
1 SMCexpect expect
(x86) 5.43.0
Installation of
The expect will installed in the /usr/local/bin directory.
The script is as follows
----------------------------------------------------------------------------------------------------------
#!/usr/local/bin/expect -f
#This is the expect script wrote to automate the sftp process to pull files from a server as per the date and #then push the files to another server.
set timeout -1
set DATE [exec date "+%Y%m%d"]
log_file "/home/ftp/logs/sftp.log"
send_log -- "####-Starting SFTP script- [exec date] \n"
send_log -- "Today's date:[exec date] \n"
send_log -- "Downloading files through sftp \n"
spawn /usr/bin/sftp jim@172.20.1.86
expect "Password:"
#sleep 5
send "jim123\n"
expect "sftp>"
send "cd /export/home/jim \r"
expect "sftp>"
send "ls \r"
expect "sftp>"
send "get *.$DATE \r"
expect "sftp>"
send "quit \r"
sleep 5
send_log -- "Today's date:[exec date] \n"
send_log -- "Uploading files through sftp \n"
spawn /usr/bin/sftp jim@172.20.5.93
expect "Password:"
send "jim123\n"
expect "sftp>"
send "cd /export/home/jim \r"
expect "sftp>"
send "put *.$DATE \r"
expect "sftp>"
send "quit \r"
#END of SCRIPT

I can shell script from expect script. I have another requirement to pull yesterdays file through sftp server. Thank god that was a Linux server and to get yesterdays date in Linux is easy :)
set DATE [exec /home/ftp/date.sh ]
The above line will call the date.sh script to get yesterdays date.
date.sh script is as below
[root@]# cat date.sh
#!/bin/bash
echo $(date --date='1 day ago' "+%Y%m%d")
#End of script
#This is the expect script wrote to automate the sftp process to pull files from a server as per the date and #then push the files to another server.
set timeout -1
set DATE [exec date "+%Y%m%d"]
log_file "/home/ftp/logs/sftp.log"
send_log -- "####-Starting SFTP script- [exec date] \n"
send_log -- "Today's date:[exec date] \n"
send_log -- "Downloading files through sftp \n"
spawn /usr/bin/sftp jim@172.20.1.86
expect "Password:"

Hi Jibby George,
ReplyDeleteThanks a lot for posting this.
I was really fed up googling this, but finally stick to your site and works perfectly.
Thankyou Man. you are so special. you made it so easy.
ThankYou
Gald that it helps you
ReplyDeleteHi Jibby,
ReplyDeleteI have a similar requirement. Your method of doing that is impressive. I tried to follow this. But, the glitch here is that the sftp user name has a special character $ in its name. While running the script the spawn/expect/send libraries are treating the text after $ symbol as a variable. Is there a way that you think of to get away with that. I tried single quotes, double quotes around the user name but no luck.
Thanks for your help.

HI Naresh , thanks for that. Its been a while I worked with expect. There should be a way to do that. If I figure out something will post here.
ReplyDeleteJibby
Great! Thanks much for your help Jibby.

Hi Jibby, found a solution to get away with the $ symbol using expect. When I place the \ (backward slash) in front of the $ symbol, then it works fine.
ReplyDeleteThanks!

How can I check to see if the password is invalid or expired? I have a similar task to automate. Nice script.
ReplyDeleteI was able to figure out my check for invalid or expired password. The system I was connecting to does not tell you if the password is invalid, it just gives the password prompt over and over that is why there is a second expect for the password prompt. I also put in a check for upper and lower case prompts. After doing the spawn of the sftp command it goes like this:
ReplyDeletespawn sftp mylogonid@someserver
expect -re "password|Password:"
send "mypasswd\r"
expect -re "password|Password:" {
puts "Password was not accepted \n"
exit 2
} -re "expired|Expired" {
puts "Password Expired \n"
exit 3
} -re "invalid|Invalid" {
puts "Password Invalid \n"
exit 4
} "sftp>" {
send "pwd\r"
expect "sftp>"
send "put myfilename yourfilename\r"
expect "sftp>"
send "bye\r"
}
I have a simple requirement and try to figure out how to do it in EXPECT.
Deleteafter sftp into a server. I want to cd into the latest directory (Note $HOME has directories and files). Any idea a easy way to achieve this??
Thanks
Worked great! Thank you!
