SVN export diff version updated file list

For operation and maintenance personnel who do not use version control on the server, every time SVN modifies files, they need to check the change log, find them one by one, and then update them to the server. The process is really painful,
so is there a way to run a command to compare Just copy the modified files and they have the same directory structure. The answer is yes.

#!/bin/bash
 
if [ ! $1 ] || [ ! $2 ] || [ ! $3 ] || [ ! $4 ]; then
    echo "Please enter a revision from, revision to, SVN repository, and target directory"
    exit
fi
 
# set up nice names for the incoming parameters to make the script more readable
revision_from=$1
revision_to=$2
repository=$3
target_directory=$4
 
# the grep is needed so we only get added/modified files and not the deleted ones or anything else
# if it's a modified directory it's " M" so won't show with this command (good)
# if it's an added directory it's still "A" so will show with this command (not so good)

# echo "svn diff --summarize -r$revision_from:$revision_to $repository | grep "^[AM]'"
 
for line in `svn diff --summarize -r$revision_from:$revision_to $repository | grep "^[AM]"`
do
    # each line in the above command in the for loop is split into two:
    # 1) the status line (containing A, M, AM, D etc)
    # 2) the full repository and filename string
    # so only export the file when it's not the status line
    if [ $line != "A" ] && [ $line != "AM" ] && [ $line != "M" ]; then
        # use sed to remove the repository from the full repo and filename
        filename=`echo "$line" |sed "s|$repository||g"`
        # don't export if it's a directory we've already created
        if [ ! -d $target_directory$filename ]; then
            directory=`dirname $filename`
            mkdir -p $target_directory$directory
            svn export -r $revision_to $line $target_directory$filename
        fi
    fi
done
 
# to summarize any deleted files or directories at the end of the script uncomment the following line
#svn diff --summarize -r$revision_from:$revision_to $repository | grep "^[D]"

Save the above code directly, change the name to svndiff, and add executable permissions

Instructions:

svndiff 前一个版本号  后一个版本号  项目路径  导出的文件存放路径
