More like this:
rprepend() {
ruby <<-EOF
f='$1'.split('|').collect{|i|i.chomp.sub(/^/,'$RSUBDIR.*')}.join('|');
puts f;
EOF
}
d...@lin4:image_library$ RSUBDIR='/path'
d...@lin4:image_library$ rprepend 'foo|bar'
/path.*foo|/path.*bar
It's a long story and it's not an application, it's part of a larger cli
utility to help me find and grep filenames and their contents in a project
and some of its nested subprojects so I can think and work that much faster
without having to pause and move around groping for the right file (from the
shell).
Thanks everyone for helping.
