这对我来说是新鲜的领域，所以我为自己的无知向您道歉。
我第一次在终端中工作，并且相信我在尝试调整安装过程中要解决的软件包的路径时弄乱了bash shell。
我正在研究macOS High Sierra 10.13.6（如果有帮助的话）。
在终端中，运行代码：
cd ~
/bin/bash
perl -MNet::FTP -e \
'$ftp = new Net::FTP("ftp.ncbi.nlm.nih.gov", Passive => 1);
$ftp->login; $ftp->binary;
$ftp->get("/entrez/entrezdirect/edirect.tar.gz");'
gunzip -c edirect.tar.gz | tar xf -
rm edirect.tar.gz
builtin exit
export PATH=$luke:$HOME/edirect >& /dev/null || setenv PATH
"$luke:$HOME/edirect"
./edirect/setup.sh
编辑自（在最后几行中将“ $ {PATH}”替换为“ $ luke”）：
cd ~
/bin/bash
perl -MNet::FTP -e \
'$ftp = new Net::FTP("ftp.ncbi.nlm.nih.gov", Passive => 1);
$ftp->login; $ftp->binary;
$ftp->get("/entrez/entrezdirect/edirect.tar.gz");'
gunzip -c edirect.tar.gz | tar xf -
rm edirect.tar.gz
builtin exit
export PATH=${PATH}:$HOME/edirect >& /dev/null || setenv PATH
"${PATH}:$HOME/edirect"
./edirect/setup.sh
运行第一个块后，运行的bash进程始终无法完成，我无法停止它。我可以使用其他外壳打开终端。但是，使用默认值（或/ bin / bash）打开将产生以下结果：

...无法输入任何内容，无法进行bash运行（有时可能是perl），并且由于自己不小心摆弄有趣的新玩具而对自己的灵魂深感失望。

很抱歉将所有内容都丢给您！ 非常感谢您将系统恢复到正常状态的任何帮助。
