我有一个看起来像这样的文本文件。
/var/www/xxx/html/TEST/VIDEOS/video3.mp4
/var/www/xxx/html/TEST/video_folder_1/cideo.mp4
/var/www/xxx/TEST/video_folder_1/sadasd
/var/www/xxx/html/TEST/video_folder_2/asdsadasdasdsadsadsadsadas
/var/www/xxx/html/TEST/video_folder_2/cideo2.mp4
/var/www/xxx/html/TEST/video_folder_2/sadsada
我希望它看起来像这样：
/var/www/xxx/TEST/video_folder_1/sadasd
/var/www/xxx/html/TEST/video_folder_2/asdsadasdasdsadsadsadsadas
/var/www/xxx/html/TEST/video_folder_2/sadsada
想法是删除任何具有扩展名的行。 I.E mp4在这种情况下。
所以我猜它会在行尾找到4个字符，看它是否有＆＃34;。＆＃34;
如果是，请删除该行。

批处理你应该能够以多种方式做到这一点：
findstr /V /L "." theFile.txt
正如Aacini建议的那样，它检查该行是否包含.并在测试时正常工作。
如果您想使用正则表达式
findstr /V /R "\....$" theFile.txt
通过检查行是否以.***
最后我建议使用它：
findstr /V /R "\.[a-z0-9]*$" theFile.txt
检查该行是否以任何类型的扩展名结尾，因此包括可能的4个字母的扩展名。
我已经对这些中的每一个进行了测试，它们都运行良好。
我真的不知道为什么Serenity会坚持使用VBscript，这无疑是一种很棒的语言，但对于这样一个简单的事情来说，这个批处理要简单得多。

这是一个vbs正则表达式替换程序。比FindStr强大得多。它可以全局工作，因此您可以定位行结尾。
这是来自我的类似生产线而非全球计划的帮助。关键是要显示示例RegEx表达式。
提取所有节标题，即没有等号的行
filter filter iv "=" < "%systemroot%\win.ini"
提取以小写字母开头的所有部分标题
filter filter n "\[[a-z].+" < "%systemroot%\win.ini"
这显示插入符号用于转义CMD.EXE的左括号和反斜杠转义为RegEx引擎的开始括号
filter filter n "\^(" < "%systemroot%\win.ini"
这表示正在搜索引号字符
filter filter n "\x22" < "%systemroot%\win.ini"
使用$ 1，$ 2，$ ...，$ n指定替换字符串中的子匹配
filter replace i "=" "No equal sign" < "%systemroot%\win.ini"
这将在方括号内搜索文本，并用cat替换该行，后跟括号内的文本
Filter replace i "^\[^(.*^)\]" "cat$1" < %windir%\win.ini
这将搜索从第11个字符到行尾的任何文本和打印。
Filter replace i "^.{10}^(.*^)$" "$1" < %windir%\win.ini
这将搜索CSV文件并打印第二个和第四个字段
Filter replace i "^.+,^(.+^),.+,^(.+^)$" "$1,$2" < csv.txt

Character Description
\ Marks the next character as either a special character or a literal. For example, "n" matches the character "n". "\n" matches a newline character. The sequence "\\" matches "\" and "\(" matches "(".
^ Matches the beginning of input.
$ Matches the end of input.
* Matches the preceding character zero or more times. For example, "zo*" matches either "z" or "zoo".
+ Matches the preceding character one or more times. For example, "zo+" matches "zoo" but not "z".
? Matches the preceding character zero or one time. For example, "a?ve?" matches the "ve" in "never".
. Matches any single character except a newline character.
(pattern) Matches pattern and remembers the match. The matched substring can be retrieved from the resulting Matches collection, using Item [0]...[n]. To match parentheses characters ( ), use "\(" or "\)".
x|y Matches either x or y. For example, "z|wood" matches "z" or "wood". "(z|w)oo" matches "zoo" or "wood".
{n} n is a nonnegative integer. Matches exactly n times. For example, "o{2}" does not match the "o" in "Bob," but matches the first two o's in "foooood".
{n,} n is a nonnegative integer. Matches at least n times. For example, "o{2,}" does not match the "o" in "Bob" and matches all the o's in "foooood." "o{1,}" is equivalent to "o+". "o{0,}" is equivalent to "o*".
{ n , m } m and n are nonnegative integers. Matches at least n and at most m times. For example, "o{1,3}" matches the first three o's in "fooooood." "o{0,1}" is equivalent to "o?".
[ xyz ] A character set. Matches any one of the enclosed characters. For example, "[abc]" matches the "a" in "plain".
[^ xyz ] A negative character set. Matches any character not enclosed. For example, "[^abc]" matches the "p" in "plain".
[ a-z ] A range of characters. Matches any character in the specified range. For example, "[a-z]" matches any lowercase alphabetic character in the range "a" through "z".
[^ m-z ] A negative range characters. Matches any character not in the specified range. For example, "[m-z]" matches any character not in the range "m" through "z".
\b Matches a word boundary, that is, the position between a word and a space. For example, "er\b" matches the "er" in "never" but not the "er" in "verb".
\B Matches a non-word boundary. "ea*r\B" matches the "ear" in "never early".
\d Matches a digit character. Equivalent to [0-9].
\D Matches a non-digit character. Equivalent to [^0-9].
\f Matches a form-feed character.
\n Matches a newline character.
\r Matches a carriage return character.
\s Matches any white space including space, tab, form-feed, etc. Equivalent to "[ \f\n\r\t\v]".
\S Matches any nonwhite space character. Equivalent to "[^ \f\n\r\t\v]".
\t Matches a tab character.
\v Matches a vertical tab character.
\w Matches any word character including underscore. Equivalent to "[A-Za-z0-9_]".
\W Matches any non-word character. Equivalent to "[^A-Za-z0-9_]".
\num Matches num, where num is a positive integer. A reference back to remembered matches. For example, "(.)\1" matches two consecutive identical characters.
\ n Matches n, where n is an octal escape value. Octal escape values must be 1, 2, or 3 digits long. For example, "\11" and "\011" both match a tab character. "\0011" is the equivalent of "\001" & "1". Octal escape values must not exceed 256. If they do, only the first two digits comprise the expression. Allows ASCII codes to be used in regular expressions.
\xn Matches n, where n is a hexadecimal escape value. Hexadecimal escape values must be exactly two digits long. For example, "\x41" matches "A". "\x041" is equivalent to "\x04" & "1". Allows ASCII codes to be used in regular expressions.

如果你想用＆＃34;消除线条。＆＃34;从your previous question中创建的输出，然后一个更简单的解决方案是在该代码中插入测试：
@echo off
setlocal EnableDelayedExpansion

if "!line:~0,1!" equ "/" (
set "header=%%a"
