Have you considered defining an alias for grep that includes the options you want to apply only when grep is invoked interactively?
Because when i grep from the command line i don't want to have to type in this every time.

Code:
'-irs --color=always --line-number --exclude-dir=.git'

if i did an alias, it could easily be stomped on by another shell or script running or if i used a different grep like BSD, it would probably choke on an alias.

i'm really looking for something simple that would just strip out the '^[K' formatting characters like with
Code:
 echo

or
Code:
printf

something that recognizes these as not to print or is so dumb that it ignores anything but the displayed string without attributes so that when i pipe something to my script file i don't have turn off or unset switches

zegrep

ZGREP(1)                                                      General Commands Manual                                                     ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  invokes  grep  on  compressed  or  gzipped  files.   These  grep  options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other options specified are passed directly to grep.  If no file is specified,  then  the
       standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and fed to grep.

       If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
