Editing Echo (command) (section)

==Examples==
<syntaxhighlight lang="doscon">
C:\>echo Hello world
Hello world
</syntaxhighlight>

Using [[ANSI escape code]] ''SGR'' sequences, compatible terminals can print out colored text.

Using a [[UNIX System III]]-style implementation:

<syntaxhighlight lang="bash">
BGRED=`echo "\033[41m"`
FGBLUE=`echo "\033[35m"`
BGGREEN=`echo "\033[42m"`
NORMAL=`echo "\033[m"`
</syntaxhighlight>

Or a Unix Version 8-style implementation (such as Bash when not in Unix-conformance mode):

<syntaxhighlight lang="bash">
BGRED=`echo -e "\033[41m"`
FGBLUE=`echo -e "\033[35m"`
BGGREEN=`echo -e "\033[42m"`
NORMAL=`echo -e "\033[m"`
</syntaxhighlight>

and after:

<syntaxhighlight lang="bash">
echo "${FGBLUE} Text in blue ${NORMAL}"
echo "Text normal"
echo "${BGRED} Background in red"
echo "${BGGREEN} Background in Green and back to Normal ${NORMAL}"
</syntaxhighlight>

Portably with <code>printf</code>:

<syntaxhighlight lang="bash">
BGRED=`printf '\33[41m'`
NORMAL=`printf '\33[m'`
printf '%s\n' "${BGRED}Text on red background${NORMAL}"
</syntaxhighlight>
