Expect Script - While file exist
Hi:

Can anyone help me with the while loop in expect script. Following is my scenario:
1. one of my process is running and looking for a file
2. as soon as the file is dropped the proces then processes the file and creates a control file ".ctl" to indicate end of process for that file
3. after the above process, I need to rename the ".ctl" file to ".done" as part of the second processing

How do I write an expect script to check if the file exists in the directory and then only rename the file from ".ctl" to ".done" extension. I can work with the if condition, but my expect script is the one that drops the file and will have to wait till the ".ctl" file is created by the process and then my expect script will rename the .ctl file to .done

set filename "abc"

expect ">$ "
while { [file exists $flname.ctl] }\
{
expect ">$ "
puts "$flname.ctl exists\r"
expect ">$ "
send "mv $flname.ctl $flname.done\r"
}

For some reason the above code doesnt do anything. I am not sure if it's the syntax or something that I am overlooking. Or is it plain that I cant use "file exists" command in a while loop.
Please advice
