How to truncate STDIN line length?

Question

I\'ve been parsing through some log files and I\'ve found that some of the lines are too long to display on one line so Terminal.app kindly wraps them onto the next line. Ho

Not exactly answering the question, but if you want to stick with Perl and use a one-liner, a possibility is:

$ perl -pe's/(?<=.{25}).*//' filename

where 25 is the desired line length.
