Yes. There are several ways to delete two tab delimited fields from a file and modify the text in another field to contain the characters "AVIALABLE " (sic). Do you want to add the new text to the start of the old 5th field, to add the new text to the end of the old 5th field, or to replace the contents of the old 5th field with "AVIALABLE "?
Why do you want to use something other than awk for this? Is this a homework assignment that does not allow use of awk? (Oops, ignore that. I see that you have changed your requirements.)
Do you want to add AVAILABLE to the end of the 2nd field as in your code, or add "AVAILABLE " as requested in your description to what was in field 5 before you deleted fields 3 and 4?

I have a large text-file with tab-delimited genetic data that looks like:

I simply wan to delete the first column, but since the file has 600 000 columns, it is not possible with awk (seems to be limited at 32k columns).

NAME
column -- columnate lists
SYNOPSIS
column [-tx] [-c columns] [-s sep] [file ...]
DESCRIPTION
The column utility formats its input into multiple columns. Rows are filled before columns. Input is taken from file operands, or, by
default, from the standard input. Empty lines are ignored.
The options are as follows:
-c Output is formatted for a display columns wide.
-s Specify a set of characters to be used to delimit columns for the -t option.
-t Determine the number of columns the input contains and create a table. Columns are delimited with whitespace, by default, or with
the characters supplied using the -s option. Useful for pretty-printing displays.
-x Fill columns before filling rows.
Column exits 0 on success, >0 if an error occurred.
ENVIRONMENT
COLUMNS The environment variable COLUMNS is used to determine the size of the screen if no other information is available.
EXAMPLES
(printf "PERM LINKS OWNER GROUP SIZE MONTH DAY HH:MM/YEAR NAME
"
; ls -l | sed 1d) | column -t
SEE ALSO
