Creating a Date named file with Expect

Hello,

I am new to TCL and Expect. I wrote an Expect script that pulls the data that I want but I would like to pull it every day and automatically assign the days date as part of the file name.

I tried playing around with exec data but I could not get teh syntax down.

my current code:

# expect -f ofcvar.txt > ofcvar_20080818.txt

Could someone help me figure out the syntax to replace the date automatically every day?

TIA,

RF
 
Code:
set tdate [clock format [clock seconds] -format %Y%m%d]

Thanks for the quick response.

If ofcvar.txt is my command reference for the expect script and I add this line of code within the file how would I call it to create the file name with the date?

My current ofcvar.txt file contents, simple I know:

set username xxx
set pass xxx
set host xxx.com

spawn telnet ${host}

expect -re "login:"
send "${username}\r"

expect "password:"
send "${pass}\r"

expect -exact "Press <enter> to continue..."
send -- "\r"

Full disclosure: I don't speak Expect.

From your first post, I don't see how the contents matter. You had
# expect -f ofcvar.txt > ofcvar_20080818.txt
and you wanted (I thought) to change 20080818 to be any current date. Assuming that Expect processes all of Tcl as well as its own exotica:
set tdate [clock format [clock seconds] -format %Y%m%d]
set newName ofcvar_
append newName $tdate
append newName ".txt"
# expect -f ofcvar.txt > $newName

This is awesome. Thanks for your help.

One more question.

When I type in the commands above at the expect prompt it works exactly like I wanted it but when I type the commands into a new tcl file and execute it it fails to send the last command successfully.

set tdate [clock format [clock seconds] -format %Y%m%d]
set newName ofcvar_
append newName $tdate
append newName ".txt"
send "expect -f ofcvar.txt > $newName\r"


I get this at the prompt:

xpect -f ofcvar.txt > ofcvar_20080819.txt

I am sure there is a simple fix. I tried with and without the # in front like your example but that did not seem to work.
 
Again, I don't speak Expect. That said, from your example, it appears that "send" and "expect" are exclusive, vis:
expect "password:"
send "${pass}\r"

So it would seem that either you want:
expect -f ofcvar.txt > $newName
or
send "-f ofcvar.txt > $newName\r"

but I don't know what either of them mean.

Resolved. I decided to place everything in one script instead of trying to call a second one within the first.

Thanks,
