disable bold font and coloring in grep

Question

I want to use the output of command:

fdisk -l | grep -i "/dev"

in my bash script.

But the problem is that it bold and highlight/color the matched output. I don't want that. I only want to print the lines that matched the criteria.

Your shell has probably a defined alias. alias grep='grep --color=auto' is rather common in ~/.bash_aliases or ~/.bashrc. You can remove the alias or replace it with

grep --color=never

You can of course use grep --color=never manually instead when you don't want colors, as it expands to grep --color=auto --color=never and the latter option overrules the former.

See grep --help, man grep or info "(grep)General Output Control" for more information.
