If you're okay with just wildcards (not full regexes), then you might try something like
如果您只接受通配符（不是完整的正则表达式），那么您可以尝试类似的方法
f='My123File.txt'
mv $f ${f/File/}
This type of shell expansion is documented here.
If you really need regexes, try
如果您真的需要正则表达式，请尝试
f='My123File.txt'
mv $f $(echo $f | sed -e 's/File//')

User rename, here's a test:
用户重命名，这里是一个测试：
$ touch My123File.txt
$ rename 's/File//' My123File.txt
See man rename. renamesupports regexps, so you can do for example this - execute somewhere safe, e.g. /tmp or so:
见man rename。rename支持正则表达式，因此您可以执行以下操作 - 在安全的地方执行，例如 /tmp 左右：
cd /tmp
rm *.txt
touch My123File.txt My456File.txt
ls *.txt
rename 's/([A-Za-z]+)(\d+)(\w+)/-999--/' *.txt
ls *.txt
yields this:
产生这个：
My123File.txt My456File.txt
File-999-123-My.txt File-999-456-My.txt

With mmv, it's a single command a lot simpler. It also has support for translations such as lowercasing a positional parameter.
使用 mmv，它是一个简单得多的命令。它还支持翻译，例如小写位置参数。
mmv '*File.txt' '#1.txt'
