By typing them, naturally :-)

In shell scripts, grep, sed & awk are the common regex using tools;
depending on what you're doing, one or another might be the most useful
one to make use of in a script.

grep does basic regex pattern matching

sed is a Stream EDitor, and can do regex substitutions etc

awk is more complex, almost like a baby version of Perl, but weirder

For my needs, grep & sed are usually enough for most simple shell
scripts, and if I need to make it complex enough that I'm considering
using awk, I just write the whole thing in Perl instead. On the other
hand, a lot of people, eveen now, use awk all the time.

In any case, there are several useful ways to get regexes into your
shell scripts, should you have the need to do so.
