Bad file descriptor error when tried to run script using do

sugarboy has asked for the wisdom of the Perl Monks concerning the following question:

Hi All,

I am trying run a perl file using do which is as follows:
do ($script);
$script will be as /home/sagar/scripts/CLI/test.pl
The do statement returns the error : Bad File descriptor
The respective file exists at the specified location
Actually this works fine on previous setup with Perl 5.8.5, when i had a new setup with 5.8.8 it started showing up problems
Any help is appreciated

Thanks,
Sagar

I don't know `do` to emit any error messages, so I find it hard to believe `do` has anything to do with the problem at hand. $ perl -e'do "nonexistent"' $ [download]	[reply] [d/l] [select]

This is a guess, but it seems very likely to be relevant: Don't print out the value of $! except very soon after a function has failed (and then only for functions that are documented to set `$!` on failure). You should not examine `$!` to try to determine if something failed. The function tells you that it failed (usually by returning a false value) and only after that you record `$!` to get a better idea as to why it failed. `$!` frequently gets set by mundane operations under the covers. Almost no functions reset `$!` if nothing failed. Next time, you might want to actually paste even a couple of lines of the actual code that you are having a problem with. Less guessing often means faster relevant answers. - tye	[reply]
