Writing to file and reading from same file

basm100 has asked for the wisdom of the Perl Monks concerning the following question:

Hi, I want to know how I can open a file for both reading and writing

My script writes data to a file, and I then want to read data from that same file in the next part of my script.

I tried closing the filehandle and reopening as a read file, but it threw up the error "open for writing at line..."

Is there an easy way to open a file for both reading and writing ? Thanx,

basm100

Here is one way to do it. Have a look at perlopentut as well. `#!/usr/bin/perl -w use strict; # Open file for reading and writing (and maybe arithmetic) open MYFILE, "+>somefile.txt" or die "Error message here: $!\n"; # Write to the file print MYFILE "These are the days\n"; print MYFILE "and these are the days\n"; # Rewind the file for reading seek(MYFILE, 0, 0); while (<MYFILE>) { print $_; } close MYFILE;` [download] -- John.
