I have joined two files with the following command.
join -j 1 <(sort f1.csv) <(sort f2.csv) > f3.csv
After joining I tried to cut two fields from f3.csv.
cat f3.csv | cut -f2,10
But it can't cut the specific fields rather printing the whole table. I edited the header line for both f1 and f2 by using sed command before joining them to create f3.csv.
sed 1d | sed '1i a\t\b........."
Both f1 and f2 are absolutely Ok. cut command works for both of them but can't work for my f3.csv. Any solution?
