Best to use only 7-bit ascii in code.

Can you write it in a way that looks a little less like line
noise? This is much easier to understand:
xfs_io -p "$0" -r -c "stat" "$file" | awk '
/^fd\.path =/ {
projid="";
gsub(/^fd\.path = \"/, "");
gsub(/\"$/, "");
path=$0
}
/^fsxattr\.projid =/ {
projid=$3;
print path ": " projid;
}'
It also needs a usage message when no files are given, and probably
a version output (-V option) as well.
Cheers,
Dave.
