方法一：明文方式保存密码

首次执行svn check或svn update等命令后，会在系统用户目录下生成.subversion目录，并在.subversion/auth/svn.simple目录下生成SVN用户的配置文件，比如：cdf4a82409609b47a18c1b93ad8db39c，文件内容如下：

steven@ubuntu2204:~$ cat "~/.subversion/auth/svn.simple/cdf4a82409609b47a18c1b93ad8db39c"
K 8
passtype
V 9
gpg-agent
K 15
svn:realmstring
V 52
<https://192.168.121.240> Subversion Repository
K 8
username
V 6
steven
END

修改.subversion/auth/svn.simple/cdf4a82409609b47a18c1b93ad8db39c文件，如下：

steven@ubuntu2204:~$ vi "~/.subversion/auth/svn.simple/cdf4a82409609b47a18c1b93ad8db39c"
steven@ubuntu2204:~$ cat "~/.subversion/auth/svn.simple/cdf4a82409609b47a18c1b93ad8db39c"
K 8
passtype
V 6
simple
K 15
svn:realmstring
V 52
<https://192.168.121.240:5443> Subversion Repository
K 8
username
V 6
steven
K 8
password
V 7
pwd1234
END

修改说明：
1.文件中K表示关键字，V表示键值，后面的数字表示下一行字符串的长度。
2.将密码保存方式由gpg-agent改为simple(明文)
3.添加steven用户密码: pwd1234

需要注意的是：若是换个SVN用户名后这个文件会被改写，以上手动修改的信息会被覆盖，需要从再手动修改。

方式二：gpg-agent加密保存

gpg-agent是一个密码管理工具，具体说明查看官网信息。
https://www.gnupg.org/

1.安装gpg-agent：

steven@ubuntu2204:~$ sudo apt-get install gpg-agent
gpg-agent (GnuPG) 2.2.27
libgcrypt 1.8.8
Copyright (C) 2021 Free Software Foundation, Inc.
License GNU GPL-3.0-or-later <https://gnu.org/licenses/gpl.html>

There is NO WARRANTY, to the extent permitted by law.

2.添加环境变量：

修改shell初始化脚本，添加GPG_TTY和GPG_AGENT_INFO两个环境变量。并使用source命令让其立即生效。

steven@ubuntu2204:~$ vi ~/.bashrc
steven@ubuntu2204:~$ cat ~/.bashrc
... ...
export GPG_TTY=$(tty)
export GPG_AGENT_INFO=`gpgconf --list-dirs agent-socket | tr -d '\n' && echo -n ::`
steven@ubuntu2204:~$ source ~/.bashrc

3.配置gpg-agent

steven@ubuntu2204:~$ vi "~/.gunpg/gpg-agent.conf"
steven@ubuntu2204:~$ cat "~/.gunpg/gpg-agent.conf"
# ╔═══════════════════════════════════════════════════════════════════════════╗
# ║ gpg-agent configuration (~/.gnupg/gpg-agent.conf)                         ║
# ║                                                                           ║
# ║ Note:                                                                     ║
# ║ After changing the configuration, reload the agent:                       ║
# ║   $ gpg-connect-agent reloadagent /bye                                    ║
# ╚═══════════════════════════════════════════════════════════════════════════╝

# Time a cache entry is valid (in seconds) default: 600
# Each time a cache entry is accessed, the entry's timer is reset
default-cache-ttl 172800

# Set the maximum time a cache entry is valid to n seconds.
# After this time a cache entry will be expired even if it has been accessed recently.
# The default is 2 hours (7200 seconds).
max-cache-ttl 604800

steven@ubuntu2204:~$ gpg-connect-agent reloadagent /bye

4.删除旧的SVN账号信息

steven@ubuntu2204:~$ rm -rf ~/.subversion

5.执行效果

steven@ubuntu2204:~$ svn update svntest
