对于以下微小的期望脚本,其函数已添加到bash配置文件中:
chai() {
expect <<- EOF
spawn ssh myuser@myserver
expect ': $'
send 'mypassword\r'
EOF
}
我们得到:
bash: /etc/profile: line 409: syntax error: unexpected end of file
那个脚本有什么问题?
最佳答案 我通常希望
heredoc终结器(EOF)位于线路的起点,例如
chai() {
expect <<- EOF
spawn ssh myuser@myserver
expect ': $'
send 'mypassword\r'
EOF
}
我看到你正在使用<< – 并且来自链接的doc:
The – option to mark a here document limit string (<<-LimitString)
suppresses leading tabs (but not spaces) in the output. This may be
useful in making a script more readable.
所以你应该检查脚本,看看你的命令前面是否有TAB. EOF遵守相同的规则.
cat <<-ENDOFMESSAGE
This is line 1 of the message.
This is line 2 of the message.
This is line 3 of the message.
This is line 4 of the message.
This is the last line of the message.
ENDOFMESSAGE
# The output of the script will be flush left.
# Leading tab in each line will not show.
