Ubuntu :: Remove Duplicate Lines From A Text File?
Dec 16, 2010Contained within each of these 67 text files is about 1 million urls. Yes. I have 67 text files that contain 1 million lines of urls each. I am sure I am swimming in duplicates. I tried opening one text file and clicking sort ----->remove duplicates. Now Gedit is not responding my processor is maxed out to 100% and I think I am finally ready to delve into some command line code. Can anyone give me idiot proof instructions on how to sort the duplicates out of each one of these 67 text files? How about no duplicates across all 67?

EDIT: i think its actually working, just taking a reallllly long time (on an old pen 4 from 2000)

Programming :: Remove Specific Lines From File
Jan 21, 2011I'm trying to come up with ideas for a simple way to strip a specific "entry" from a text file.I know tools like sed and perl can remove specific lines from a file but I haven't been able to come up with an elegant way to do my group of lines.In my file, the first "Location" line and the "SVNPath" line should be unique every time... but are they enough to strip out the whole set of the group plus the trailing one line of white space separating each group? Add to this, my file will grow as new entries are added (always appended to the end) but new entries will have the same formatting.
