Thanks a lot Jotne
But I guess we should give file name too after the command as follows. Where we have file named df_test_removing_column in which we want to remove
3rd and 4th column.

Code:

$ m=3
$ n=4
$ awk '{$a="";$b=""} 1' a=$m b=$n df_test_removing_column

Output should be as follows. It is just an exmaple for df (Disk space of AIX server.)

Code:

Filesystem 512-blocks   Iused %Iused Mounted on
/dev/hd4 262144   5812 9% /
/dev/hd2 9175040   79431 7% /usr
/dev/hd9var 3014656   3968 2% /var
/dev/hd3 2097152   113 1% /tmp
/proc -   - - /proc
/dev/hd10opt 1048576   1741 2% /opt
/dev/lv_home 720896   853 1% /home
/dev/lv_hd 524288   55 1% /opt/hd

Thanks,
