how do I do this...
 

text file 1 has 5000 unique lines, text file 2 has 500 unique lines

I want to remove each *entire line* containing the data on text file 2, from file 1, leaving me 4500 lines

!I don't know php!

!I barely know excel (well, open office) but if it's doable in that I can follow simpleton instructions :) !

Ideally an online place similar to textmechanic.com, where I load one, load the other, and hey presto.

thanks in advance, and I might even thank you again afterwards for double the fun :thumbsup

how about simple file splitting ?

like for 10 parts ? it gives you 500 lines which u can extract later

fdupes -r /some/directory/path > /some/directory/path/fdupes.log

or if you want a GUI:

Google is awesome.

If I understand correctly, you want to simply look up all the data in list #2 to find a match on list #1, then remove that record?

A slightly inefficient method would be to use a single Excel workbook, then place list #1 in one sheet (tab) and sheet two in another. Give the data in sheet a range name and then using @vlookup in an adjacent empty cell on the first line of list #1 to perform a lookup. Se the condition that if a Match is found, then insert "Y" into that cell.

At that point, drag the vlookup formula down the column to apply it to all records in the first list. Then you can simply sort the list #1 by the vlookup column, and highlight/delete all the ones with a "Y" on them.

Someone else can likely provide a more efficient method, but this should work if you have exact match records. Use F1 inside Excel for help on using the vlookup function or a simple Google query will show you all sorts of usage examples.

ETA: see? I knew someone else would post something more efficient :D

correct mate :thumbsup

I'm praying there's an easier way to do this :D

I've already posted two.

Dur.

gaymian - your GUI suggestion doesn't do what I need it to (nor is it a full version).

Notepad++ can do this in 5 seconds with TextFX.

(*) Lines will have to be sorted either ascending or descending though if you use the first method.


Otherwise... Use a regex.

useful stuff :thumbsup

edit...I saw that you tried textmechanic.com...Are you sure you can't do it there?

I would use UltraCompare. It's part of the UltraEdit suite. Pretty sure you can get a free trial.

regex, wc>@blah etc - waaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaay over my head...

onehunglo - don't think it does what I want - the lines on files 1 & 2 aren't the same, so aren't duplicates as such.

eg file 1 consists of:

line1: info data blahblah OH-LOOK-THIS-PHRASE-1 etc etc more data on this line
line2: info data blahblah OH-LOOK-THIS-PHRASE-2 etc etc more data on this line
line3: info data blahblah OH-LOOK-THIS-PHRASE-3 etc etc more data on this line
--
line5000: info data blahblah OH-LOOK-THIS-PHRASE-5000 etc etc more data on this line

file 2 consists of:
line1: OH-LOOK-THIS-PHRASE-1
line2: OH-LOOK-THIS-PHRASE-2
line3: OH-LOOK-THIS-PHRASE-3
--
line450: OH-LOOK-THIS-PHRASE-450

what I need:
input file 1, input file 2, and have it seek file 1 for OH-LOOK-THIS-PHRASE-X, and remove that entire line.

bump for this shift in case there's an easy way while I wait for my coder bloke to get back from holiday (and try ultracompare)

Oh that is genius! You took the first bit of my name and changed it to GAY!

HiLARious!

almost as funny as you following dvt around and using:

bummer boy
spacker
likes bumming men
looking for men to bum
lollington
ad hominem
now I know why people got the hump with me and markham
etc

over and over and over and over. Why don't you fuck off out of this biz thread wankstain, it's annoying keep having to 'view post' when you post in my biz threads.

You're a fucking cock, you don't like me, I don't like you, so fuck off. Or don't, and go look up the word provocation, and how it's a viable defence in assault cases.

Cue 'wahwah' remarks, 'oh are you THREATENING me???' variations, 'hmm, bannable offence' bollocks, or any other of your predictable and tedious as fuck posts. don't forget the grammer mistaikes as well, mr im-too-stupid-to-realise-i-act-like-the-precocious-11-year-old-kid-that-thinks-he-is-funny-but-everyone-thinks-is-an-out-and-out-cunt :thumbsup

they aren't duplicate lines - see post #13 :)

still to fire up ultracompare to see if that does the trick
