(Unfortunately I'm not familiar enough with the Unix command line to provide that wrapper, but a bit of googling should help.
With a wrapper that includes all files you need to change, this method is obviously quicker than opening every file in an editor. $ cat yourfile | sort | uniq > yourfile_nodups In the stackoverflow question referenced above, Pablo Santa Cruz also mentions a simple method to sort and output via Cygwin command line:
You can then paste the newly cleaned unique text lines back into a file for saving. This tool will compare all the lines in your text and then find and remove all of the identical lines. Quick solution (use the following menu option): Edit -> Line Operations -> Remove Duplicate Lines. In Notepad++, there's an option to sort and remove duplicates in one go (TextFX/TextFX Tools/Sort lines with option Sort outputs only UNIQUE active), but it only works on the active file, so you'll have to open all files. Quickly paste text from a file into the form below to remove all duplicate lines from your text. In this short article, we would like to show how in a simple way remove duplicated lines in Notepad++. I'm unfamiliar with Perl, but any one-liner will only get rid of consecutive duplicates, so you'll have to sort first if you want to get rid of non-consecutive ones in a simple way (and if line order is not an issue), and I don't see any sorting happen in that Perl directive. Perl -ne "print unless $a++" inputfile.txt > outputfile.txt Not sure, but I suspect this one also sorts the lines before removing the duplicates. If the duplicates can occur anywhere in the file, you either have to accept that the lines are sorted before removing the duplicates (, or else you have to use a database (like Access), setting up a table that doesn't accept duplicates (but then Access imposes a character limit of 255 I believe). To make it insensitive to trailing spaces, you'll have to adapt the regex (or simply delete all trailing spaces beforehand in another operation). The "Match case" option sets the regex to case-sensitive or case-insensitive. The regex solution suggested above didnt remove all duplicate lines for me, but just the. Remove Empty Lines ( Containing Blank Characters) It removes the empty or blank characters line from the entire file. Edit > Line Operations > Remove Consecutive Duplicate Lines.
