Hi,
Thanks guys for all the suggestions. Most helpfull. I got the print
outs I wanted to take with me on my flight. 51 hours of flights so
plenty of time to digest ruby code.
Regards
Matthew Winter

why involve xargs at all?
find -type f -name '*.rb' -exec cat {} \;
Because this forks and execs 'cat' for every single file,
which can be a lot slower.
Find also scans all your .git/.svn directories etc, which
means you get a lot of false hits on a grep. I use two
small shell scripts in my ~/bin directory:
==> /Users/cjh/bin/files0 <==
find "$...@-.}" -type f \( -path \*.git\* -prune -o -path \*.svn\* -
prune -o -path \*.swp -prune -o -print \) |
sort | tr '\n' '\0'
==> /Users/cjh/bin/grep0 <==
xargs -0 egrep "$@"
The find script sorts the filenames (something find doesn't do),
but also handles files with spaces in the names.
The use of quotes $@ means you can pass any additional
arguments, even ones with quoted spaces in them.
Typical usage:
files0 app/models | grep0 'Thing to find'
