Removing a character at specific position in a column
Hi,

I have a file like this (about 8 columns in total, this being the 2nd column)
Code:
gi_49482297_ref_YP_039521.1_
gi_49482297_ref_YP_039521.1_
gi_49482315_ref_YP_039539.1_
gi_49482315_ref_YP_039539.1_

I want to remove the _ at the end of the line.
And at later stages I would want to replace the _ with another character perhaps.

how can I do it using awk or sed?

Any help would be highly appreciated.

neaten

NEATEN(1)						      General Commands Manual							 NEATEN(1)

NAME

       neaten - neaten up output columns

SYNOPSIS

       neaten [ format ]

DESCRIPTION

       Neaten  reads  from  its standard input and neatens up columns separated by white space using the specified format.  The format is a string
       consisting of a positive integer followed by an alignment character and another integer.  The alignment	character  is  usually	a  decimal
       point ('.'), but it can be any non-digit.

       The  alignment  character  is used as the central point of each column.	The total column field width will be the number to the left of the
       alignment character plus one for the alignment character itself plus the number to the right of the alignment character.

       If a field does not contain the alignment character, it will be printed to the left of where the alignment character would  have  appeared.
       If  a  field  is  too long to print within the specified format, the entire field will be printed and that row will not be aligned with the
       rest.

       The default format is "8.8".

EXAMPLE

       To examine a file with columns of numbers:

	 neaten 10.8 < input | more

BUGS

       Columns wider than the total width of the format specification will be printed without any separating white space.

       The program does not do anything special with tabs on the input.
