asset version in unity cache server

 (for i in `find ./ -type f`; do export version=`head -c 100 $i | strings | awk '/^4\.[0-9]+/'`; echo "$i:$version"; done;) > /tmp/cache_versions.txt

format nginx config

cat nginx.conf | awk '{sub(/^[ \t]+/,"");a=0} /\{/{l++;a=1} /\}/{l--} {id="";for(i=a;i<l;i++)id=sprintf("%s%s", id, "\t");printf "%s%s\n", id, $0}'

remove conditional compiler statements

for i in `find ./ -type f | xargs grep -sl '#if'`; do  awk 'BEGIN {p = 1; n = 0} { if(n == 1) {n=0; p=1} if($1 ~ /(#if)/){ p = 0 }; if($1 ~/(#endif)/) {n = 1}; if(p == 1) {print } }' $i > $i.b; mv $i.b $i; done;
