[mocore]

 url to local path
with awk to shell

idk if its useful for much tbh 

Code: [Select]




# tc_uri
# $1=$url
# $2=$local_prefix_path
#
# eg tc_uri  "$url"  "$local_path_prefix"
#
# eg tc_uri http://tinycorelinux.net/13.x/x86/tcz/info.lst.gz /tmp
#
function tc_uri(){
 url="${1-'http://tinycorelinux.net/13.x/x86/tcz/provides.db.gz'}";
 shift
 echo "$url" | busybox awk -v path_prefix="$1" -F"/" '

function get_path(u    ,path ){
  colafter=5

  split(u,path,"/")
  path_length=length(path)
  p=""
  pc=0
  for(i in path) { 
   if(  i > colafter && i <= path_length  -1 ) {
    pc=(pc+1);
    if(pc>1){ p=p"/"path[i] }else{ p=path[i] }
   }
  }
  return p ;
 }

function mkpathstr(u){ 
               protocall=$1"//"
               domain=$2
               path=get_path($0)
               remotepath=$0
               file=$NF
               ver=$4
               arch=$5
               localpath=path_prefix"/"ver"/"arch"/"path"/"file
             }

{
  mkpathstr($0)

  # return vars from awk
  print protocall,  remotepath , path , file , ver , arch ,localpath
 
}

' ;  }

 url="$1"
 pathprefix="$2"

# read vars into script
read protocall remotepath path file ver arch localpath  < <( tc_uri "${@}" )

echo -e "vars:\nprotocall : $protocall \nremotepath : $remotepath \npath : $path \nfile : $file  \nver  : $ver \narch : $arch \nlocalpath : $localpath "

# eg ?..
# mkdir -p $(dirname $localpath)
# wget -O$localpath $remotepath

modified script
 - to use set to pass args from awk
 - remove the (bash) process substitution ,
https://en.wikipedia.org/wiki/Process_substitution
https://stackoverflow.com/questions/30781969/difference-on-bash-and-ash-parentheses

..& found ash "process substitution" alternative using "file descriptors"
