How to get CSV dimensions from terminal

Question

Suppose I'm in a folder where ls returns Test.csv. What command do I enter to get the number of rows and columns of Test.csv (a standard comma separated file)?

Answer 1

Try using awk. It's best suited for well formatted csv file manipulations.

awk -F, 'END {printf "Number of Rows : %s\nNumber of Columns = %s\n", NR, NF}' Test.csv

-F, specifies , as a field separator in csv file.

At the end of file traversal, NR and NF have values of number of rows and columns respectively

Another quick and dirty approach would be like

# Number of Rows
cat Test.csv | wc -l

# Number of Columns
head -1 Test.csv | sed 's/,/\t/g' | wc -w
