一条命令中的Linux shell单引号和双引号

Question

我需要你的帮助才能使这个命令生效:

ssh -t user@localhost "cd /tmp ; PROMPT_COMMAND='echo -ne "\033]0;log\007"' ; bash"

这是我得到的错误:

bash: -c: line 0: unexpected EOF while looking for matching `''
bash: -c: line 1: syntax error: unexpected end of file
Connection to localhost closed.
log007' ; bash: command not found

谢谢

我建议用反斜杠转义双引号 (\"):

ssh -t user@localhost "cd /tmp ; PROMPT_COMMAND='echo -ne \"\033]0;log\007\"' ; bash"
