Delete an entire column from a tab delimited file
Hi,

Can anyone please tell me about how we can delete an entire column from a tab delimited file?

Mu input_file.txt looks like this:

Quote:
Name Postcode Fund ISIN
ABC TN16 9BE Franklin UK Mid Cap Fund A Inc GBP GB00B3ZGH246
ABC BH15 2BX Templeton Global Bond A Mdis GBP H1 LU0316492692
And I want the output as:
Quote:
Postcode Fund ISIN
TN16 9BE Franklin UK Mid Cap Fund A Inc GBP GB00B3ZGH246
BH15 2BX Templeton Global Bond A Mdis GBP H1 LU0316492692
I used the below code
Code:
nawk -v d="1" 'BEGIN{FS=OFS="\t"}{$d=""}{print}' input_file.txt

But in the output, the first column is coming as NULL and then the remaining columns are printed.

Thanks

Try
Code:
while read a b c
do
print b c
done<file > out

or..

Code:
nawk 'BEGIN{FS=OFS="\t"}{sub($1FS,"")}1' input_file.txt

The simplest solution is to use a tool that was designed precisely for this task. To "cut" out the first column:
Code:
cut -f2- file
