Re: [9fans] union directories exploration

[cinap_lenrek@gmx.de]

this has been done before. i can't remember who wrote it
and i couldnt find it in the contrib index.

#!/bin/rc

fn get_dirs {
	tmp = /tmp/$pid ^_dirs
	echo -n > $tmp

	for (f in `{du -nf $root_in | awk '{print $2}' })
		ls -l $f | grep '^d' | awk '{print $10}' >> $tmp
	dirs = `{sort $tmp}
	rm $tmp
}

root_in=$1
root_out=$2

if(~ $3 '')
	get_dirs;
if not
	dirs = `{cat $3};

for(i in $dirs){
	o=`{echo $i | awk '{gsub(ENVIRON["root_in"], ENVIRON["root_out"], $0); print}'}
	echo bind -bc $i $o
}


theres also divergefs.
