File::Temp can be used to create and open temporary
files safely. The tempfile( )
function returns the name and the open filehandle of a temporary file.
The tempdir( )
function creates a
temporary directory. File::Temp guarantees that race conditions cannot
occur since it returns both a filehandle and filename. In addition,
File::Temp checks for safe file and directory permissions, so the
sticky bits are checked for group-writable directories. To write a
temp file into /tmp (default), you would do
something like the following:
#!/usr/local/bin/perl -w use File::Temp qw(tempfile); my($fh, $filename) = tempfile( ); print "opening $filename for writing... "; print $fh "some data ... ";
