Re^2: substitute 4 spaces instead of a tab

With regards to not truncating anything accidentally, davido mentioned this excellent suggestion: move the original file out of the way first (e.g. if it's called shock_api.h, call it shock_api.h.bak or similar; there's a built-in called rename to do this), then read in from shock_api.h.bak and write out to shock_api.h.

This solves the simultaneous read/write truncation issue, and creates a backup for you in case things go awry.

In fact my suggestion isn't exactly original either. Take a look at perlrun under the `-i` flag. When you instruct Perl do to in-place edits from the command line like this, "`perl -i.bak .....`" you get essentially the same behavior. Dave	[reply] [d/l] [select]
