删除文本文件中带有“.”的行批处理文件
Remove lines in text files that have "." Batch File
我有一个如下所示的文本文件。
/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
我们的想法是删除任何有扩展名的行。 I.E mp4 在这种情况下。
所以我猜它会在行尾查找 4 个字符，看看它是否有“.”。
如果是，请删除该行。
这是一个vbs正则表达式替换程序。远比 FindStr 强大。它适用于全球，因此您可以定位行结尾。
这是来自我的一个类似的基于行的、非全局的程序的帮助。重点是显示示例 RegEx 表达式。
提取所有部分headers，即没有等号的行
filter filter iv "=" < "%systemroot%\win.ini"
提取所有以小写字母开头的部分headers
filter filter n "\[[a-z].+" < "%systemroot%\win.ini"
这显示插入符号转义 CMD.EXE 的左括号，反斜杠转义正则表达式引擎
的左括号
filter filter n "\^(" < "%systemroot%\win.ini"
这表示搜索引号字符
filter filter n "\x22" < "%systemroot%\win.ini"
使用 $1, $2, $..., $n 指定替换字符串中的子匹配项
filter replace i "=" "No equal sign" < "%systemroot%\win.ini"
这将搜索方括号内的文本，并将该行替换为 cat 后跟括号内的文本
Filter replace i "^\[^(.*^)\]" "cat" < %windir%\win.ini
这会搜索任何文本并从第 11 个字符打印到行尾。
Filter replace i "^.{10}^(.*^)$" "" < %windir%\win.ini
这将搜索 CSV 文件并打印第二个和第四个字段
Filter replace i "^.+,^(.+^),.+,^(.+^)$" "," < 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, "(.)" 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, "" and "1" both match a tab character. "[=19=]11" is the equivalent of "[=19=]1" & "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.

在批处理中，您应该可以通过多种方式执行此操作：
findstr /V /L "." theFile.txt
正如 Aacini 所建议的那样，它检查该行是否包含 . 并且在测试时工作正常。
如果你想使用正则表达式
findstr /V /R "\....$" theFile.txt
通过检查一行是否以 .***
结尾来完全满足您的要求
最后我推荐的是使用这个：
findstr /V /R "\.[a-z0-9]*$" 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。
我已经测试了每一个，它们都工作正常。
我真的不知道为什么 Serenity 坚持要你使用 VBscript，这无疑是一种很棒的语言，但对于像这个批处理这样简单的事情要简单得多。
如果你想去掉带“.”的行根据 中创建的输出，一个更简单的解决方案是在该代码中插入一个测试：
@echo off

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