如何通过 Bash 脚本在 SFTP 会话中运行命令？

Question

I am trying to run the cd command in a bash script to a SFTP session. My code currently looks like

#!/bin/bash
sftp $1@$2

and then I want to use cd within the SFTP session and other commands too but cd is fine for now. How can I do this?

Try the batch mode. Quoting the man page:

     -b batchfile
             Batch mode reads a series of commands from an input
             batchfile instead of stdin.  Since it lacks user
             interaction it should be used in conjunction with non-
             interactive authentication to obviate the need to enter a
             password at connection time (see sshd(8) and ssh-keygen(1)
             for details).

             A batchfile of ‘-’ may be used to indicate standard input.
             sftp will abort if any of the following commands fail: get,
             put, reget, reput, rename, ln, rm, mkdir, chdir, ls,
             lchdir, chmod, chown, chgrp, lpwd, df, symlink, and lmkdir.

             Termination on error can be suppressed on a command by
             command basis by prefixing the command with a ‘-’ character
             (for example, -rm /tmp/blah*).  Echo of the command may be
             suppressed by prefixing the command with a ‘@’ character.
             These two prefixes may be combined in any order, for
             example -@ls /bsd.
