Perl one-liners explained

Peteris, Just thought I'd drop you a note to thank you for spending the time to produce this book. I find it's well written and explains things very clearly. It's also fun to work though. The only thing I struggled with was creating a suitable file to test the one liners on - I was in Vim staring at a blank screen for about 5 minutes. If I get writers block trying to create a 'somefile', then I can appreciate how hard it must be to write a book!
Great work, looking forward to any other works you publish.
Thanks for the comment and I am glad that you liked my book! I never thought about including a file to test one-liners on, and it's a great suggestion. I'll make sure to include the files in my next revision of this book and my future books.
Until then, I can share the files that I used to test one-liners on.
The first one contains just 10 lines. I call this file n. I use it to test line spacing, matching lines, numbering lines, text conversion and other tasks.
Then I have the n2 file that is double-spaced version of n. I use it to test one liners such as 'number only non-blank lines in files' and 'delete all blank lines from a file'.
Then I have this crazy file called crazy that I used to test most everything else:
line one hello wold
line two foor bar baz
line three esr rms lbt
line four french english spanish
line five c cpp perl
line six energy power work
line seven integral matrix set
repeated line muahaha
line eight pen stool lamp
line nine you me him
line ten coffee tee pop last
That's about it. :)
Haha, thanks! You've made learning AWK an easy, but profitable job. Take care.
