nth Columns in a Tab delimited file

Hi

Can anyone help me to identify the nth field from a Tab delimited file?

Thanks

Using cut command you can identify a particular field for the specified delimiter.

General format:

Code:
cut -d"<delimter>" -f"<field_number>" filename

You need to specify the tab delimiter by the -d option.

But you can not hit tab key because shell will not accept tab key. Also you can not give '\t' as its argument.Because cut -d expects a single character as its argument.

To give tab stop in the shell you just hit ctrl+v and ctrl+i


Code:
cut -d '     '  -f 4 file # Here the tab given inside the single quotes by using ctrl+v and ctrl+i

Try awk:

awk '{ print $4 }' file
