bash:警告並提供將受rsync命令影响的檔案數

我的 rsync 的 --dry-run 輸出是：

% rsync --dry-run -avi --delete-after /home/blueray/Documents/rsync-test/src /home/blueray/Documents/rsync-test/dest
building file list ... done
.d..t...... src/
>f.st...... src/empty-asciidoc-document 3.adoc
>f+++++++++ src/empty-asciidoc-document 4.adoc
>f+++++++++ src/empty-asciidoc-document-renamed.adoc
*deleting   src/empty-asciidoc-document.adoc
*deleting   src/empty-asciidoc-document 2.adoc
sent 254 bytes  received 27 bytes  562.00 bytes/sec
total size is 16  speedup is 0.06 (DRY RUN)

我正在尋找如下輸出：

building file list ... done
.d..t...... src/
>f.st...... src/empty-asciidoc-document 3.adoc
>f+++++++++ src/empty-asciidoc-document 4.adoc
>f+++++++++ src/empty-asciidoc-document-renamed.adoc
*deleting   src/empty-asciidoc-document.adoc
*deleting   src/empty-asciidoc-document 2.adoc
sent 254 bytes  received 27 bytes  562.00 bytes/sec
total size is 16  speedup is 0.06 (DRY RUN)
Warning: n files will be affected, do you want to continue?

到目前為止，我想到的指令碼是：

#!/bin/bash
affected_files=$(rsync --dry-run -avi --delete-after /home/blueray/Documents/rsync-test/src /home/blueray/Documents/rsync-test/dest)
echo $affected_files
number_of_affected_files=$(echo $affected_files | grep src | wc -l)
echo "Warning: ${number_of_affected_files} files will be affected, do you want to continue?"
while true; do
    case $yn in
        [Yy]* ) rsync -avi --delete-after /home/blueray/Documents/rsync-test/src /home/blueray/Documents/rsync-test/dest; break;;
        [Nn]* ) exit;;
        * ) read -p "Please answer yes or no: " yn;;
    esac
done

但是，它有一些問题. $affected_files 不保持換行符.因此，该指令碼無法正常工作.而且，我不確定是否 $affected_files | grep src | wc -l 是否提供實際數量的受影响檔案。

我该怎麼办？

bash

shellscript

rsync

在這裏執行OP，我当前使用的指令碼是：

#!/bin/bash
rsync -ab --dry-run --stats --human-readable --inplace --debug=NONE --log-file=rsync.log --backup-dir=rsync_bak.$(date +"%d-%m-%y_%I-%M-%S%P") --log-file-format='%t %f %o %M' --delete-after /home/blueray/Documents/rsync-testsrc /home/blueray/Documents/rsync-testdest | sed -e '1d;5,12d;14,17d'
echo -e "\nDo you want to continue?"
while true; do
    case $yn in
        [Yy]* ) rsync -ab --human-readable --inplace --info=PROGRESS2,BACKUP,DEL --debug=NONE --log-file=/home/blueray/Documents/rsync-testdest/rsync.log --backup-dir=rsync_bak.$(date +"%d-%m-%y_%I-%M-%S%P") --log-file-format='%t %f %o %M' --delete-after /home/blueray/Documents/rsync-testsrc /home/blueray/Documents/rsync-testdest; break;;
        [Nn]* ) exit;;
        * ) read -p "Please answer yes or no: " yn;;
    esac
done
