blank-line

I've got an input file like this: line 1 line 2 line 3 line 4 line 5 line 6 I'd like to use awk to insert a blank line every few lines; for example, every two: line 1 line 2 line 3 line 4 line 5 line 6 How can I get awk to put a blank line into my file every n lines? A more "awk-ish" way to write smcameron's answer: awk -v n=5 '1; NR % n == 0 {print ""}' The "1;" is a condition that is always true, and will trigger the default action which is to print the current line. smcameron awk '{ if ((NR % 5) == 0) printf("\n"); print; }' for n == 5 , of course. Substitute whatever your idea of n is.

I spent some time trying to figure out how to delete all blank lines in Visual Studio Code and I can't get it working. Anybody knows how to do it please? If I search for ^$ while typing it in search field VSC does find the blank lines (completely blank lines, means no white spaces) but it doesn't remove them when I hit Replace All. It does nothing: For blank lines with spaces ^\s+$ Search works, but it does not remove them. What it does is it replaces them with a blank line without spaces :)) It must be I am doing something wrong. I just can't figure out what is it. Anybody knows? Thanks. For

Is it possible to remove all blank ROWS from a CSV file? I'm trying to count all rows from a CSV file but would like to exclude lines that doesn't contain a value on a specific column or the whole row. This is what I'm using to count the rows as of the moment. $import = file($target_path, FILE_SKIP_EMPTY_LINES); $num_rows = count($import); echo $num_rows; sample: Jun,Bronse,137 Raven,Princeton,TX,75407,2147088671,Nell@Gmail.Com,1990,CHEVROLET,K1500,, ,,,,,,,,,,,, ,,,,,,,,,,,, ,,,,,,,,,,,, Nella,Brown,111 Venna St,Princeton,TX,75407,2147177671,lakb@Gmail.Com,1993,CHEVROLET,K1500,, Jun,Bronse

I've successfully written a script which takes a string to search for in a specific file, and then outputs the line where it first occurs, and then I take that value into a for-loop and skips parsing that number of lines and write its contents to a new file. However I do not get blank lines which I find quite problematic to solve. The string I'm searching for is "/]", caches the line number where it occurs, then accumulates it into a variable with comma-seperation. I then take that variable into a for-loop again and retrieve the first occurring value as my final "skip this number of lines"
