Thanks for all the answers.
I decided to use the sed based solution. It is a wonderful tool, although for people coming from Dos/Windows world the syntax is somewhat obscure...
Btw. after some googling I found a list of very useful sed one liners:
http://sed.sourceforge.net/sed1line.txt |
Yes, it's true that regular expressions aren't easy at first. But once you understand how they work, they are so powerful. It's amazing the amount of stuff one can do with grep and sed.
Perl is even more powerful and can do it all, but again one has to learn how to use it. Anyway, whether sed, perl, awk(?), many paths lead to Rome  |
I suggest to Richard that you could just learn Perl and be done with it. Perl has powerful regular expressions, is a full scripting language and is just about as expressive as any language can be. You could write one-liners on the command line (without getting out the editor) with the -e switch which will do amazing things. And when a one-liner is not quite enough Perl let's you do amazingly powerful stuff in just a few lines of code.
Your problem for example is solved like this using perl:
perl -e 'while (<>) { s/\s+$//; print $_."\n"; }' <win.txt > unix.txt
This assumes you run this script from unix. It will take all the white space out of the end of each line and then re-print it with the unix "\n" line ending.
I believe a way that would work on both windows and unix is this:
perl -e 'while (<>) { s/\s+$//; print $_ . chr(10); }' <win.txt > unix.txt
