""" | |
Like cut, but for CSVs. To be used from a shell command line. | |
Change row[1] to the row index to be printed. row[1] will print the second | |
item in the row. | |
Note that fields are zero-based, as opposed to 'cut' where they are 1-based. | |
Leveraged from/motivated by an example from @bycoffe | |
Usage: | |
csvcut foobar.csv | |
(prints the first column of each row of foobar.csv) | |
head -10 foobar.csv | csvcut -f 0,2 | |
(prints the first and third columns of the first ten lines of foobar.csv) | |
