in reply to Re^4: header footer
in thread header footer
Consider the following instead:
use strict; use warnings; use autodie; open my $FILE1, '<', 'input.txt'; open my $FILE2, '>', 'output.txt'; while (<$FILE1>) { s/^HDR.{47}|FTR.+//; print $FILE2 $_; } close $FILE1; close $FILE2;
- autodie will trap the file i/o errors (you're not handling these, but you should)
- Use only lexical (my) file handles
- Use while to iterate through the file
- The two substitutions were combined into one
If FTR marks the footer to the end of the line, you can just use FTR.+ to remove it, since in your example there were only 30 characters left--including FTR. However, it's certainly OK to use FTR.{27}, if you prefer.
