This could be easy for many people on this list yet I am hopeless. This is want I want to do. I have plain text files ranging from 20K to 100K they all contain words. However there are blank lines in between the words. I want to automate the deletion of the blank lines how can I do this ? Could be a macrop with a wordprocessor also what ever will do the job is fine with me.

This can be done with awk : gawk ' NF>=1 {print $0} ' file.in > file.out This works good for a file or two If you have many files to convert you need to write a little script but it depends on the file names that need to be converted -- Mertz Denis

Remove the comment if you want to remove "empty" lines with spaces-only too. I have tested it and it works for my files. But no guarantees. Oh... the files are not backed up... So back'em up yourself first. Save this file as delemptylines.pl and invoke it like: perl delemptylines.pl file1 file2 file3 ... <p>while ($file = shift(@ARGV)) { print "Processing $file\n"; if ( ! open (F, "<$file")) { warn "Can't open $file for reading ($!)\n"; next; } undef $/; $_=<F>; close (F); # s/\n\s+\n/\n/g; # Removed "empty" lines with spaces-only. s/\n+/\n/g; if (! open (F,">$file")) { warn "Can't open $file for writing ($!)\n"; next; } print F $_; } <p>Cheers, -- Koos Pol ---------------------------------------------------------------------- S.C.

Try
perl -ne 'print unless /^\s*$/' -i~ *
Or: perl -ne 'print unless /^[\s|\t]*$/o' -i~ * ^^^^^^^ to skip lines which contain spaces and/or tabs. The 'o' adds a little more speed in case you have *big* files. By the way Stefan's neat one-liner saves the original files with a ~ behind them. <p>Bye, Martijn -- = Martijn van den Burg = Think globally = = Publications Department, ASML = Act locally = = Voice: +31 (0)40 268 3856 = = = Fax: +31 (0)40 268 2960 = =

\s matches [ \t\n\r\f] so that change is redundant. /o forces just one regex recompilation, which is exactly how many you get by default if the regex doesn't contain a variable interpolation (which this one doesn't). That change is redundant too.

There's been several answers, but none using vi (or ex). In vi, I would do in command mode: :map t jddt Them place the cursor in the first line and press t
