我正在尝试在 Ubuntu 16.04 上的本 wiki 中概述的Expect 中进行加密。我已经安装了tcllib
root@alarmux:/home/abdmin# apt-get install tcllib
Reading package lists... Done

tcllib is already the newest version (1.17-dfsg-1).
0 upgraded, 0 newly installed, 0 to remove and 77 not upgraded.
但是，当我运行我的脚本时，我得到：
couldn't execute "des": no such file or directory
while executing
"exec echo "$pd" | des -e -k $key -b > /home/abdmin/$filename"
(procedure "utility_encrypt" line 3)
invoked from within
"utility_encrypt pswd encrypted_Pass"
(file "./tclTest" line 22)
为什么des命令不能执行？
