extract lines containing
« on: September 23, 2013, 04:55:17 PM »
hello
can you tell me please how to search inside a bunch of text files and "extract'' all the lines that contain *something* in a list into a new text file?
thanks!

from a command line you can issue the Find command and redirect the results to a text file

if you want to use wildcards I think you have to use the Find command inside a For statement

look up Find, For, and redirecting output in a Command Line reference

qgrep -y findme *.txt > results.txt

That's on a Windows platform with qgrep (from one of the old resource kits).  The -y means case insensitive, findme is the string to find (you could look for multiple words with "one two" instead, it will find lines with either), you're searching through all the .txt files and directing the output to a file.

Of course there are more options with a real grep, depending on your platform.

1) Directory
2) Text search
3) Text to search for
4) File filter
5) Select to display Content

When it's finished, select all the results and copy to clipboard, you can then paste them into a file.

Nowadays we even have 'findstr' on Win7:

Code: [Select]
FINDSTR [/B] [/E] [/L] [/R] [/S] [/I] [/X] [/V] [/N] [/M] [/O] [/P]
        [/F:Datei] [/C:Zeichenfolge] [/G:Datei] [/D:Verzeichnisliste]
        [/A:Farbattribute] [/OFF[LINE]] Zeichenfolgen
        [[Laufwerk:][Pfad]Dateiname[ ...]]

C:\>FindStr /R myregexsearchpattern C:\Temp\*.txt > C:\Temp\results.txt


- - -

hehehe, the circle closes   :P :

Along the way, qgrep somehow changed its name to findstr.

TextPad has a "Find in Files" command that lets you search content of files within your specified path.
Search pattern can be a regular expression & you can limit which type(s) of files are searched.
Although it doesn't directly export the search results to a new file, you can easily SaveAs the results output.
(you'll probably first want to search/replace to remove the filename+lineNumber from start of each line)
