Programming :: TCL / Expect - IF Results Are Different Then Send A Command?
Dec 11, 2010trying to see IF i dont get the right results repeat the command until it will or quit after 3 tries....
expect -exact "->"
send -- "test_read_register 0,0x37
"
if {! [regexp {Address 0x00000000} do send -- "test_read_register 0,0x37

It should read
Read: Address 0x00000037, Data: 0x0000000b
but sometimes it comes out to this
Read: Address 0x00000000, Data: 0x00000000
therefore ill have to run the command again IF I Dont get the right results...
Programming :: /usr/bin/expect : Script To Check Server Load Using Both Expect And Bash?
Jul 27, 2010I am trying to make a script that can be used to check server load on a remote server and produces sound on our local machine, when server load exceeds a particular limit.1. I want to execute command uptime or uptime | awk '{print$10}'on the remote server and store the result in a variable(say x), and later use it in the bash script.
Bash Part

Programming :: Pass An Expect Command Result Into A Variable And Then Use It Again?
May 4, 2010I'm trying to create a program that would locate the oldest file of a certain type on a server. Here's the commands:
OLDEST_PATH=`find -L / -depth -maxdepth 6 -mindepth 6 -type d | sort -f | head -1`
OLDEST_FILE=`find -L $OLDEST_PATH | grep .mp3 | sort -f | head -1`
ls -al $OLDEST_FILE
I'm writing this all in expect but I'm having problems. The main problem I have is whenever I try to run the first command, I can't seem to isolate the result of the OLDEST_PATH so that the 2nd command will work. There always seems to be a newline in the variable and the result is only "find -L" command running and it bypasses the variable. If I can just figure out how to get the 1st and 2nd command to work, then I can figure out the 3rd. Here's some code:
Code:
send "find -L / -depth -maxdepth 6 -mindepth 6 -type d | sort -f | head -1
"
sleep 20
expect -re "(.*)
[Code]....
I know there is a better way to write this. I've tried multiple ways and this just happens to be the last way I've tried it. If you try running this, you'll notice that there is still carriage returns after the result of OLDEST_PATH and it prevents the 2nd "find" command from working properly.

Jun 5, 2011I am literally bashing (pun intended) my head against the keyboard at this minute! I am trying to automate a script via cron for my centos server. The script requires two user inputs (e.g. read VAR). However, I do not want to edit the original file, as I would like to be able to run it normally as well. It is also made by someone else, and so if an update becomes available, it will be easier to install. My idea is that i create a cron script, to run this second script from, and the only way i could find was with expect. However I am having troubles, In order to test out expect, I have created the following:
test.sh
[Code]...
It looks as if the second input is completely ignored ?! what i am doing wrong? or if there is a more elegant solution to running a script from a script with user inputs?

Programming :: HTML To PHP To EXPECT Formatting?
Apr 13, 2011I wrote an expect script that tests user authentication against a RADIUS server. The username is an email address, including an @ sign. I recently wrote an HTML/PHP front end to allow others to input username/password into a form and then see the results when they hit submit. Expect code that takes two args username, and password
Code:
expect "#"
send "test aaa group radius [lindex $argv 0] [lindex $argv 1] new-code
"expect "#"
[code]....
Every works as it's supposed to, except for the output of the script. When it displays on the webpage, it's segmented weirdly with all throughout. What I've found is when I remove the @ sign in the username input, it fixes it. Is there any part of HTML or PHP that treats the @ as a special character? 1 more thing is that I have another HTML/PHP/EXP script that works fine with the @.

Script is being run on Linux Red Hat,
In one of the grep/awk's the output (currently) are 2 columns (min max), i.e....| awk '{print $1, $2}' | sort -u which outputs (e.g.)
The number of "min max" pairs varies from file to file. Want to output a single column of unique numbers from the min max pairs & get the number of them for input to a file...i.e...
Where <PROCESS> is some process/technique that will generate a single column of integers (increment of 1) to pipe into the next one (sort -u)
i.e. (example from above)
Have tried command seq - only works for single pair input i.e.
Is there any command like seq etc which will output a single column based on a input of min max numbers (increment 1) to pipe onwards to next command?

Programming :: Expect/TCL Logging - Create A Clean Log File?
Apr 14, 2011I've written an Expect script that assists with change management on Cisco devices. The script creates log files for pre-change, the change itself, and post-change. Each log and its commands is triggered by a ! command. For example:
Code:
./dochange.exp hostname
<script spawns bash, user SSHes to hostname>
!PRE
[code]....
All of this works fine. My big hair-pulling hiccup is that the resulting log files are filled with raw backspace characters! I am using log_file to log the output from the script. I stop and restart logging with a new file when needed. However, the log files are pretty much unusable. After doing some research, it looks like log_file sends output to the file in real-time, unbuffered. When I hit a key, it's immediately sent to the log. What I would like is for only the resulting string to go to the log. If I start to type 'reload' and instead type 'show run', I don't want 'reload' to be listed in the log at all.

Programming :: TCL Expect Script That Spawns A Telnet Session To A Nortel - Response In Expect_out Is Not Consistent
Dec 2, 2010I have a TCL expect script that spawns a telnet session to a Nortel DMS100 to execute some commands. The strange thing is that the response in expect_out is not consistent. It sometimes contains a extra enter or newline. This results in differences in the expect out buffer. Here is a part of the script:
send "time
"
sleep 1
expect -re ">"
[code]...
This command displays the time. The correct output should be (with log_user=1):
>time
Time is 11:44:04
>
But sometimes the output is:
>timeTime is 11:45:04
>
As you can see here the is missing on the command that expect sends , or at least in the echo that is comming back. I use a split command to filter out the response in the expect_out buffer, but this fails when the is missing. Here is a example with the debug enabled:
[code]....
I suspect it has something to do with a slow response of the switch. I tried to send the time command slow and with the send_human but the result is the same. A timeout between the send and expect also doesn't help.
