search for list of filenames in a single file

[ladduq]

Hi

Need help to search for list of filenames in a single file.

Lets say the file information.txt contains lakhs of filenames but i only need to get a list of hundred filenames with all the instances in that file.

lets say information.txt contains

1 1.txt
2 2.txt
3 3.txt
4 2.txt
5 4.txt
6 5.txt
7 2.txt
8 6.txt
9 2.txt
10 1.txt

if the search criteris is "1.txt" and "2.txt"
the output should be

start
=================
1 1.txt
2 2.txt
4 2.txt
7 2.txt
9 2.txt
10 1.txt
=====================
end

the same should be applicable for any no of files with any no of instances as in this case we have only 2 files as our search criteria.

Regards
Ladduq

C:\temp>findstr "1.txt 2.txt" information.txt
1 1.txt
2 2.txt
4 2.txt
7 2.txt
9 2.txt
10 1.txt
C:\temp>

That search will be treated as a regex, and the dot will match any character. Not what is wanted.

You need to add the /L (literal) option to the findstr command.

Also, you can't search for file names that contain spaces that way. For spaces you need the /c:"search" option.

I thought that regex was only used when you specify /R. Is that not the case?

No, it defaults to regex

Good one Microsoft. Nice of them to include a /R switch.

C:\temp>findstr "1.txt 2.txt" information.txt
1 1.txt
2 2.txt
4 2.txt
7 2.txt
9 2.txt
10 1.txt
C:\temp>

You should search for " 1.txt" so 11.txt or 101.txt are excluded. (of course with /C as others already mentioned).

Hmm...

[foxidrive]

That's normal. What are you trying to say?

it's no regexps

Code: Select all

@echo off
type nul> "Crystal Reports Shifts01.pdf"
type nul> "Crystal Reports Shifts02.pdf"
type nul> "Crystal Reports Shifts03.pdf"
type nul> "Crystal Reports Shifts04.pdf"

dir /b |findstr ..pdf

del "Crystal Reports Shifts0?.pdf"

pause

With the literal string /c: switch it switches to literal mode.
