The Geekery

I love one-liners¹ to make my life easier.  Today I decided to clean up a directory full of CSV files, and compress them down.  After all, a 2MB CSV file can be reduced quite substantially, and I had 300 of them.

Here it is, quite simply loops through the directory of CSVs, and zips the file up, keeping the name the same.

for i in `ls -1 *.csv`; do zip -m ${i%csv}zip ${i}; done

This all goes on a single line, but can easily be written out over multiple lines, like this:

for i in `ls -1 *.csv`;

do

  zip -m ${i%csv}zip ${i}

done

Doing this reduced the folder size down from 600MB, to about 70MB, about an eighth the size.
