Yes, thanks many & very appreciate that..
By the way, what if i've a various numeric number at all the line in my file and i just intend to replace the 1st digit only with character "X". Example,

my file
ddpadsgag506xghssuyj_3#ods
ddpadsga446xghssuys_47#523
ddsadsgagh396xghssuy_te_3.4
ddsadsgag506xghssuy_pe_3.35
ddsadsgag326xghssuys
ddsadsgag506ighssuys_eng
ddsadsgag506pghssuyk

result
ddpadsgagX06xghssuyj_3#ods
ddpadsgaX46xghssuys_47#523
ddsadsgaghX96xghssuy_te_3.4
ddsadsgagX06xghssuy_pe_3.35
ddsadsgagX26xghssuys
ddsadsgagX06ighssuys_eng
ddsadsgagX06pghssuyk

And what command should i apply to eliminate the content after _3 at end of the line. Example,

my file
ddpadsgagX06xghssuyj_3#ods
ddsadsgaghX96xghssuy_te_3.4
ddsadsgagX06xghssuy_pe_3.35

result
ddpadsgagX06xghssuyj_3
ddsadsgaghX96xghssuy_te_3
ddsadsgagX06xghssuy_pe_3

evim

EVIM(1) 						      General Commands Manual							   EVIM(1)

NAME

       evim - easy Vim, edit a file with Vim and setup for modeless editing

SYNOPSIS

       evim [options] [file ..]
       eview

DESCRIPTION

       eVim  starts  Vim and sets options to make it behave like a modeless editor.  This is still Vim but used as a point-and-click editor.  This
       feels a lot like using Notepad on MS-Windows.  eVim will always run in the GUI, to enable the use of menus and toolbar.

       Only to be used for people who really can't work with Vim in the normal way.  Editing will be much less efficient.

       eview is the same, but starts in read-only mode.  It works just like evim -R.

       See vim(1) for details about Vim, options, etc.

       The 'insertmode' option is set to be able to type text directly.
       Mappings are setup to make Copy and Paste work with the MS-Windows keys.  CTRL-X cuts text, CTRL-C copies text and CTRL-V pastes text.  Use
       CTRL-Q to obtain the original meaning of CTRL-V.

OPTIONS

       See vim(1).

FILES

       /usr/share/vim/vim61/evim.vim
		      The script loaded to initialize eVim.

AKA

       Also  Known  As "Vim for gumbies".  When using evim you are expected to take a handkerchief, make a knot in each corner and wear it on your
       head.

SEE ALSO

       vim(1)

AUTHOR

       Most of Vim was made by Bram Moolenaar, with a lot of help from others.	See the Help/Credits menu.
