Perl调试器可以将ReadLine历史记录保存到文件吗？

HISTORYFILE

~/.perldb

&parse_options(\"HistFile=$ENV{HOME}/.perldb.hist\");

parse_options(\"TTY=/dev/stdin ReadLine=0\");

rlwrap -H .perl_history perl -d ...

$ export PERLDB_OPTS=HistFile=$HOME/.perldb.history 

&parse_options(\"HistFile=$ENV{HOME}/.perldb.hist\");

export PERLDB_OPTS=HistFile=$HOME/.perldb.history

source .bashrc

perl -d my program.pl

perldb: Must not source insecure rcfile /home/ics/.perldb.
        You or the superuser must be the owner, and it must not 
        be writable by anyone but its owner.

chmod 700 ~/.perldb
