ap's Issues

一运行ls就卡住了

终端不能响应任何操作，子进程处在僵尸的状态

root       21568    8739 99 18:40 pts/7    00:00:10 ap ls
root       21573   21568  0 18:40 ?        00:00:00 [ls] <defunct>

kill -SIGQUIT 21568 显示程序卡在了keepCopying

   main.keepCopying({0x4e82c0, 0xc0000a0300}, {0x4e8340, 0xc0000ba020})

能否在定义alias之前检查是否已经存在定义的alias

例如在bash中已经定义了ls

alias ls='ls $LS_OPTIONS -lA'

现在 eval "$(ap --bash)"之后，alias变成了如下定义

alias ls='ap ls'

能否实现eval之后把ls定义为

alias ls='ap  $LS_OPTIONS -lA'

csh 和 tcsh 支持吗？

ctrl+z的行为和预期不符

^Z 应当让程序后台挂起，并返回当前shell，使用fg/bg让任务继续在前台/后台运行。
