如何通过 SFTP 将远程服务器上 LS 的输出通过管道传输到本地文件系统？答案

【问题描述】：

我在命令行通过 SFTP 登录到远程服务器。我所在的文件夹包含数十万个文件。我需要在文本文件中获取这些文件的列表，以便以编程方式访问它们，因为没有一个 PHP SFTP 客户端能够返回如此大的文件列表。

当我在目录上（在 SFTP 会话中）运行 ls 时，文件列表最终显示大约需要 20 分钟。

我在此服务器上没有写入权限，因此我无法将输出通过管道传输到远程服务器上的文件。

如何将输出通过管道传输到本地计算机上的文本文件...或以其他方式将文件列表获取到本地计算机？

如果您远程执行，Wu 的答案很好。如果您已登录到远程服务器并希望将文件发送回自己的家，这是另一种选择：

your_command | ssh username@server "cat > filename.txt"

如果您有 ssh 访问权限，那将非常容易：

ssh user@server ls > foo.txt

否则，您可以将 sftp 的 STDOUT 和 STDERR 重定向到文件。你必须盲目地输入密码和命令。

如果您愿意等待 20 分钟让数据在屏幕上滚动，您可以使用“脚本”捕获所有输出。

在启动 ssh 或 sftp 会话之前调用“脚本”，它会将所有终端输出捕获到本地磁盘。键入“exit”以完成捕获。

NAME
     script -- make typescript of terminal session

SYNOPSIS
     script [-akq] [-t time] [file [command ...]]

DESCRIPTION
     The script utility makes a typescript of everything printed on your ter-
     minal.  It is useful for students who need a hardcopy record of an inter-
     active session as proof of an assignment, as the typescript file can be
     printed out later with lpr(1).

     If the argument file is given, script saves all dialogue in file.  If no
     file name is given, the typescript is saved in the file typescript.

     If the argument command is given, script will run the specified command
     with an optional argument vector instead of an interactive shell.

     The following options are available:

     -a      Append the output to file or typescript, retaining the prior con-
             tents.

     -k      Log keys sent to program as well as output.

     -q      Run in quiet mode, omit the start and stop status messages.

     -t time
             Specify time interval between flushing script output file.  A
             value of 0 causes script to flush for every character I/O event.
             The default interval is 30 seconds.

     The script ends when the forked shell (or command) exits (a control-D to
     exit the Bourne shell (sh(1)), and exit, logout or control-D (if
     ignoreeof is not set) for the C-shell, csh(1)).

     Certain interactive commands, such as vi(1), create garbage in the type-
     script file.  The script utility works best with commands that do not
     manipulate the screen.  The results are meant to emulate a hardcopy ter-
     minal, not an addressable one.

ENVIRONMENT
     The following environment variable is utilized by script:

     SHELL  If the variable SHELL exists, the shell forked by script will be
            that shell.  If SHELL is not set, the Bourne shell is assumed.
            (Most shells set this variable automatically).

SEE ALSO
     csh(1) (for the history mechanism).

HISTORY
     The script command appeared in 3.0BSD.

BUGS
     The script utility places everything in the log file, including linefeeds
     and backspaces.  This is not what the naive user expects.

     It is not possible to specify a command without also naming the script
     file because of argument parsing compatibility issues.

     When running in -k mode, echo cancelling is far from ideal.  The slave
     terminal mode is checked for ECHO mode to check when to avoid manual echo
     logging.  This does not work when in a raw mode where the program being
     run is doing manual echo.

这很好 - script script.log 将启动脚本会话并将输出存储到名为“script.log”的文件中。
