in thread Write to filehandle without deleting current text

When the Read Mode file handler doesn’t to utilize another process you closed the file hander.

Then open the file a file handler in Write Mode with the same file name and print the contents you will the new (updated) contents in the sample file.

#!/usr/bin/perl $fileName = "abc"; open(IN, "<", "$fileName") or die "Could not open file $fileName"; read IN, my $new, -s IN, close (IN); $new =~ s/foo/bar/g; # Open the the file in write mode open(OUT, ">", "$fileName") or die "Could not open file $fileName"; # print the new contents print OUT $new; close (OUT);
