Hello everyone, i've been searching for close to a week now on this issue with so far no luck. I'm really at a dead end of where to go from here. This is my issue.

I have a fresh install of Fedora 6 with expect and tcl installed by doing the following:

yum install tcl
yum install expect

Code:

[root@intelligen Routerscript]# autoexpect manymaint.exp
autoexpect started, file is script.exp
couldn't execute "manymaint.exp": no such file or directory
    while executing
"spawn -noecho manymaint.exp"
    ("eval" body line 1)
    invoked from within
"eval spawn -noecho $argv"
    invoked from within
"if {[llength $argv]>0} {
        eval spawn -noecho $argv
        cmd "spawn $argv"
} else {
        spawn -noecho $env(SHELL)
        cmd "spawn \$env(SHELL)"
}"
    (file "/usr/bin/autoexpect" line 315)

So after a bit of reading it I thought maybe it needed to be ran with expect and this is what i get running with expect.

Code:

[root@intelligen Routerscript]# expect ./manymaint.exp
invalid .command .name "savescript="y""
    while execudting
"savescript="y""
    (file "./manymaint.exp" line 19)

I'm lost on what to do but i'm really thinking my tcl isn't correctly installed. Could anyone help me out? I'm in crunch time before end of year. Thank you!

(I would post the remaining question but the forum says I must have 5 posts before you can post URL's/Links but i'm not posting anything like that. Can a mod help me out?)

Hello Intelligen,

Welcome to nixCraft forum!

The limit is placed because of spammers. If you are regular user, after 5 post you will able to post URLS.

You can paste your code between

Code:

[code]your code[/code]

I think both are installed correctly; try as follows:

Code:

chmod +x manymaint.exp
./manymaint.exp

Also paste output of following command

Code:

head -1 manymaint.exp

I chmod the script yesterday and i believe i have correct rights on it now:

Code:

-rwxr-xr-x 1 root root    8672 Dec 12 20:38 manymaint.exp

I will PM you the location i got the script

Here is the output

Code:

[root@intelligen Routerscript]# head -1 ./manymaint.exp
#!/bin/sh

This is => http://expect.nist.gov/scripts/manymaint shell script and not expect script. Following output Line clearly indicates that this is a shell script:

Code:

#!/bin/sh

How do you run shell script?

Code:

chmod +x manymaint
./manymaint

To identify script use file command

Code:

file manymaint

What os and are you using? What you are trying to do? Router script??? Give me details so I can may point out more info

I apologize, my linux knowledge is very low. More of a windows administrator.

I am using Fedora 6. I tried to type out what i was doing in first post but it kept saying i needed 5 posts or more. Weird! What i'm trying to do change 300 router SNMP private and public strings.

We used the manymaint script before which generates a script.exp script.
So when i download manymaint its a .txt, what SHOULD i be renaming it too?

I've did the chmod and rights look as follows:

Code:

-rwxr-xr-x 1 root root    8672 Dec 12 20:38 manymaint

When i run the script with the following:

Code:

[root@intelligen Routerscript]# ./manymaint

I get the following...

Code:

[root@intelligen Routerscript]# ./manymaint
bash: ./manymaint: /bin/sh^M: bad interpreter: No such file or directory

Create a sym link and try again

Code:

ln -s /bin/bash /bin/sh

I understand your windows background but keep working and one day you will master Linux

Cheers

Yup, i just need to keep with it. I need to install it as my main OS to force me to figure things out.

Ok when creating the symbolic link i get this:

Code:

[root@intelligen Routerscript]# ln -s /bin/bash /bin/sh
ln: creating symbolic link `/bin/sh' to `/bin/bash': File exists

I think i figured it out. Since i had edited in notepad on a windows system the file was reading incorrectly as found when i searched on google.

This is what it said:

Quote:

DOS: CRLF both. Which is why if you do "cat -v" on a DOS file you'll see a "^M" (control m is carriage return) at the end of each line. And that is why scripts don't work when written with Microsoft Notepad. The kernel looks for "/bin/sh^M" which doesn't exist. There's a "/bin/sh", but nothing with a "^M" appended.

So i then did a the following

Code:

vim
set ff=unix

That took care of problem and script ran great!
