Forums Developers problem with /filter -a command

//filter -fac $sys(lista).txt mirc.txt $remove($1-,0) *.mp3*

i want use that, for save the result of the mp3 list, to mirc.txt removing the 0 of the code... if the .mp3 iswm the line.. is an example, but i cant remove the string... with is bad?

Put this in the remote and type /test

• alias test {
  .fopen -no test mirc.txt
  filter -fk $sys(lista).txt _remove_zero *.mp3*
  .fclose test
  }
  
  alias -l _remove_zero .fwrite -n test $remove($1-,0)
