About:
Expect is a tool for automating interactive applications such as telnet, ftp, passwd, fsck, and more.

This allows scripts to control programs that require user interaction, making it ideal for testing and automation.

  • Pattern matching on program output
  • Automated input generation
  • Built-in Tcl scripting language
  • Handles interactive programs like ssh, ftp, and telnet
