Say you have a 10GB csv file and you want to add a text in the end of each line.
Obviously, opening it in vim work cut it
oh will it? ... let me confirm ... I tried and vim crushed :( ...
"So, what do we do?" I asked my conscious self while googling and stack-overflow-ing with 10+ tabs opened.
Viola! one of my stack-overflow tab came through and the answer was sed - a stream editor.
sed -r 's/text_to_find/text_to_replace/' input_file > output_file # example sed -r 's/\r/|the_text\r/' big_file.csv > output.csv
Basically, what it does here is;
-r this option represent extended regular expression
\r represent EOL, so replace EOL with
the_text plus EOL(so that the output won't be a single line file)
The rest i.e... input and output file is self explanatory.
Writing is exhausting, I'm done. I have being told to be positive, so i'm scratching this and the line below. Now i have to search for a cover image, smh.
Thanks for your one minute, hopefully I will write again.
