使用heredoc重定向命令输出

Question

我有这样的命令：

sftp user@host <<EOF
put file.txt
exit
EOF

现在我想把它的输出传递给zenity --progress，但我找不到放置它的地方。

# SFTP doesn't work anymore
sftp user@host | zenity --progress <<EOF
put file.txt
exit
EOF

# Invalid syntax, no end of heredoc
sftp user@host <<EOF
put file.txt
exit
EOF | zenity --progress

# Not picked as part of the command
sftp user@host <<EOF
put file.txt
exit
EOF
| zenity --progress

# Does not help
sftp user@host | zenity --progress <<EOF
put file.txt
exit
EOF\
| zenity --progress 

Answer 1

这应该可以解决问题：

sftp user@host <<EOF | zenity --progress
...
EOF
