Remove lines in text files that have "." Batch File - batch-file

Question

I have a text file that looks like this.
/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
I would like it to look like this:
/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
The idea would be to remove any line that have an extension. I.E mp4 in this case.
So I guess it would look for 4 character in at the end of the line and see if it has a "."
If it does, remove the line.

Answer 1

In batch you should be able to do this in many ways:
findstr /V /L "." theFile.txt
As Aacini suggests, which checks if the line contains a . and works fine when tested.
If you want to user regular expression
findstr /V /R "\....$" theFile.txt
Which does exactly what you asked for by checking if a line ends with a .***
Lastly what I would recommend is using this:
findstr /V /R "\.[a-z0-9]*$" theFile.txt
which checks if the line ends with any sort of extension, thus including possible 4-letter extensions.
I have tested each of these and they all work fine.
I really don't know why Serenity insists you use VBscript which is no doubt a great language but for a simple thing like this batch is so much more simpler.

Answer 2

This is a vbs regex replace program. Far more powerful than FindStr. It works globably so you can target line endings.
This is help from a similar line based, not global, program of mine. The point is to show sample RegEx expressions.
To extract all section headers, ie, lines without an equal sign
filter filter iv "=" < "%systemroot%\win.ini"
To extract all section headers starting with a lower case letter
filter filter n "\[[a-z].+" < "%systemroot%\win.ini"
This shows the caret escaping an opening bracket for CMD.EXE and the backslash escaping the opening bracket for the RegEx engine
filter filter n "\^(" < "%systemroot%\win.ini"
This shows searching for a quote character
filter filter n "\x22" < "%systemroot%\win.ini"
Use $1, $2, $..., $n to specify sub matches in the replace string
filter replace i "=" "No equal sign" < "%systemroot%\win.ini"
This searches for text within square brackets and replaces the line with cat followed by the text within brackets
Filter replace i "^\[^(.*^)\]" "cat$1" < %windir%\win.ini
This searches for any text and prints from the 11th character to the end of the line.
Filter replace i "^.{10}^(.*^)$" "$1" < %windir%\win.ini
This searches a CSV file and prints the second and fourth field
Filter replace i "^.+,^(.+^),.+,^(.+^)$" "$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.

Answer 3

If you want to eliminate lines with "." from the output created in your previous question, then a much simpler solution is to insert a test in that code:
#echo off
setlocal EnableDelayedExpansion
(for /F "delims=" %%a in (test.txt) do (
set "line=%%a"
if "!line:~0,1!" equ "/" (
set "header=%%a"
) else (
if "!line:.=!" equ "!line!" echo !header:~0,-1!/%%a
)
)) > testnew.txt
