bash - How do I change the column name of a CSV file? -

i have multiple csv files looks this:

col1,col2 val1,val2 

i want change col2 in each file column2. how edit csv file's column name bash?

use sed.

sed -i '1s/col2/column2/' file.csv

for multiple files, can use loop:

for f in file1.csv file2.csv file3.csv sed -i '1s/col2/column2/' $f done 

or can use find execute sed:

find . -name *.csv -exec sed -i '1s/col2/column2/' {} \;

this replace col2 in csvs in current directory , sub-directories column2.
