Change or-operator (or use parenthesis).

Hi,
I am trying to save data in an xml file.
What I am seeing is when I enable the file locking commands
the file is completely wiped out.Just zero bytes.
But it works correctly when I remove the file locking commands.
Please help ?? What I am
questions here ?
- Can I use file locking (flock command) mechanism while
writing/reading
from the XML
or there is some mechanism to avoid Reader/Writer problem ?
- Can it be used with XML processing or is it used only when you
open
the file.In my case
All locking modules use advisory locking hence it is not possible to
ensure that the file is not being touched unless you build the
intelligence into all possible scripts

I am using File::Copy to move a file from one directory to another. However, I do not
want to move the file if it is being written to (by another program).
Do i need to lock the file before moving it or does File::Copy by nature wait until a
file is not being written to before moving?

Hi All,
I am writing a modperl webapp (the new web interface for the RipeNCC whois
database server) and I have need to store some data to a file.
Nothing heavy, just a few one liners like user query strings, screen used,
server process time and a few others to do some analysis work on potential

Hi,
I'm trying to use file locking to work with the same file from
different scripts.
Each script may open the file in different mode.
For example:
Script1 opens for APPEND and Script2 opens the file for writing,
thus truncating the file and then writing the data.
I have rea
this should lock the file:
open(FH, ">>somefile.log") or print "can't append to file: $!";
flock(FH, 2) or die "can't flock file: $!";
# ~ output to file
close FH;

Hi,
I have an html form that when submitted writes to a log file.
How can I get a lock on this log file?
-because currently if multiple users submit simultaneously, then it leaves
the log file in a mess.
TIA.
