BASH scripting lesson 10 working with CSV files

260 ratings | 45730 views
More videos like this online at http://www.theurbanpenguin.com We now have some more great fun and see how much we can use the shell for; creating reports easily from the command line against CSV files. The script should be quite easy to read now as we use a while loop to read in the CSV file. We change the file delimiter to be the comma and then we have the line that we read in broken up into the schema elements we need. A report then is easy with colours and search ability. This is very usable

Put dot slash (./) before the command name.

+sn3akyp3te You have to create the file parsecsv.sh with a text editor like Vi(Vim).

You are my hero. I dont get part about bringing back IFS, why you once assigned it to coma and then set it back to initial configuration?
Leroy Diocotlhe (4 years ago)
Quote " IFS defaults to whitespace , this variable determines how your shell recognizes fields, or word boundaries, when it interprets character strings." Unquote Since CSV works with commas, IFS needs to know this in order for your shell to separate the fields correctly whenever it reads the CSV. Setting it back is just good behaviour. :)
