找不到csh命令总是出现在ubuntu终端中

Question

我想在ubuntu下使用终端运行一个程序。我使用以下命令安装了csh：

sudo apt-get install csh

并且已成功安装，输出为：

Reading package lists... Done
Building dependency tree       
Reading state information... Done
csh is already the newest version (20110502-2.1ubuntu1).
0 upgraded, 0 newly installed, 0 to remove and 230 not upgraded.

当我编写以下命令时，它没有工作：

shaimaa@ubuntu:~/MT_inv/bin$ #!/bin/csh -f
shaimaa@ubuntu:~/MT_inv/bin$ sudo MT_inversion.csh SS SS TEST
sudo: MT_inversion.csh: command not found

如何运行程序或让终端定义/找到命令？
