Not getting complete data for a executed command in log file through exp->log

dinesh14.nish has asked for the wisdom of the Perl Monks concerning the following question:

Hi All, I am using perl expect module to run commands on remote systems and using "$exp->log_file" method to read the whole session. Now in some the cases where data is very huge, the complete output of a command does not get saved in log file. For example one of the command produces more than 1 MB of data, in this case only 300/400 MB data gets saved in log file. IS there any way by which I can get complete data in log file?

Looking at the Expect docs, I had the thought that maybe you ran into a time out. The FAQ entry entitled "I just want to read the output of a process without expect()ing anything. How can I do this?" triggered the thought, and you may wish to review that section. Hope that helps.	[reply]

In general, transferring large amounts of data through Expect is not a great idea. In any case, show us your code!	[reply]
