How to unbuffer and capture output of LFTP EOF command?

问题

我有以下命令用于使用LFTP镜像一些文件：

  1. unbuffer lftp $PROTOCOL://$URL -u ${USER},${PASS} << EOF >> ${LOGSTDOUT}
  2. set dns:fatal-timeout never
  3. set sftp:auto-confirm yes
  4. set mirror:use-pget-n 50
  5. set mirror:parallel-transfer-count 2
  6. set mirror:parallel-directories yes
  7. set mirror:include-regex $REGEX
  8. set log:enabled/xfer yes
  9. set log:file/xfer $LOG
  10. set xfer:use-temp-file yes
  11. set xfer:temp-file-name *.lftp
  12. mirror -c -v --loop --Remove-source-dirs "$REMOTEDIR" "$LOCALDIR"
  13. quit
  14. EOF

我正在尝试捕获此命令的输出。我已经使用xfer输出到日志文件，但遗憾的是这不会显示我所需的进度百分比。

有什么想法吗？我的上述尝试使用unbuffer是不成功的。

英文:

I have the following command to mirror some files with LFTP:

  1. unbuffer lftp $PROTOCOL://$URL -u ${USER},${PASS} &lt;&lt; EOF &gt; ${LOGSTDOUT}
  2. set dns:fatal-timeout never
  3. set sftp:auto-confirm yes
  4. set mirror:use-pget-n 50
  5. set mirror:parallel-transfer-count 2
  6. set mirror:parallel-directories yes
  7. set mirror:include-regex $REGEX
  8. set log:enabled/xfer yes
  9. set log:file/xfer $LOG
  10. set xfer:use-temp-file yes
  11. set xfer:temp-file-name *.lftp
  12. mirror -c -v --loop --Remove-source-dirs &quot;$REMOTEDIR&quot; &quot;$LOCALDIR&quot;
  13. quit
  14. EOF

I am trying to capture the output of this command. I already output to a log file using xfer, but this sadly doesn't show the handy progress % that I desire.

Any thoughts? My above attempt with unbuffer is unsuccessful.

感谢@pjh的建议，我采用了以下使用script的解决方案：

  1. env TERM=dumb script -a $LOGSTDOUT -c "$(cat <<- EOF
  2.     lftp $PROTOCOL://$URL -u ${USER},${PASS} <<- EOFF
  3.     set dns:fatal-timeout never
  4.     set sftp:auto-confirm yes
  5.     set mirror:use-pget-n 50
  6.     set mirror:parallel-transfer-count 2
  7.     set mirror:parallel-directories yes
  8.     set mirror:include-regex $REGEX
  9.     set log:enabled/xfer yes
  10.     set log:file/xfer $LOG
  11.     set xfer:use-temp-file yes
  12.     set xfer:temp-file-name *.lftp
  13.     mirror -c -v --loop --Remove-source-dirs "$REMOTEDIR" "$LOCALDIR"
  14.     quit
  15.     EOFF
  16. EOF
  17. )"
英文:

Thanks to the suggestion of @pjh I have come to the following solution using script:

  1. env TERM=dumb script -a $LOGSTDOUT -c &quot;$(cat &lt;&lt;- EOF
  2. 	lftp $PROTOCOL://$URL -u ${USER},${PASS} &lt;&lt; EOFF
  3. 	set dns:fatal-timeout never
  4. 	set sftp:auto-confirm yes
  5. 	set mirror:use-pget-n 50
  6. 	set mirror:parallel-transfer-count 2
  7. 	set mirror:parallel-directories yes
  8. 	set mirror:include-regex $REGEX
  9. 	set log:enabled/xfer yes
  10. 	set log:file/xfer $LOG
  11. 	set xfer:use-temp-file yes
  12. 	set xfer:temp-file-name *.lftp
  13. 	mirror -c -v --loop --Remove-source-dirs &quot;$REMOTEDIR&quot; &quot;$LOCALDIR&quot;
  14. 	quit
  15. 	EOFF
  16. EOF
  17. )&quot;

The env TERM=dumb is a random line I found that removes ANSI escape codes from the output to file.
