How to chkconfig off and on Multiple services with a bash script

This has more applications than with just the chkconfig command. However, I found this script to be useful and wanted to add it to my database of useful scripts.

This script will chkconfig off the services listed in the services variable.


#!/bin/bash
# chkconfig-services-off.sh
#

# Add services here
services="vsftpd yum-updatesd vncserver sendmail"

arr=$(echo $services | tr " " "\n")
for x in $arr
do
/sbin/chkconfig $x off &amp;>/dev/null || echo -e "\033[1m * Service $x not exists\033[0m"

By changing the off to on, the script will chkconfig on the services listed in the services variable.


#!/bin/bash
# chkconfig-services-on.sh
#

# Add services here
services="vsftpd yum-updatesd vncserver sendmail"

arr=$(echo $services | tr " " "\n")
for x in $arr
do
/sbin/chkconfig $x on &amp;>/dev/null || echo -e "\033[1m * Service $x not exists\033[0m"

Here is the breakdown of one of the components of this script where I needed clarification. It turns out that those \033[1m and \033[0m are used for changing the default color of the text.

echo -e "\033[1m * Service $x not exists\033[0m"

This is a great writeup with additional colors.

Here is a list of colors:

30 = black
31 = red
32 = green
33 = yellow
34 = blue
35 = magenta
36 = cyan
37 = lightgray

Now these are the basic colors.

Usage of "\033[":
 This is to handle the console cursor.
* 'm' character at the end of each of the following sentences is used as a stop character, where the system should stop and parse the \033[ syntax.

\033[0m - is the default color for the console
\033[0;#m - is the color of the text, where # is one of the codes above
\033[1m - makes text bold
\033[1;#m - makes colored text bold**
\033[2;#m - colors text according to # but darker
\033[4;#m - colors text in # and underlines
\033[7;#m - colors the background according to #
\033[9;#m - colors text and strikes it
\033[A - moves cursor one line above
\033[B - moves cursor one line under
\033[C - moves cursor one spacing to the right
\033[D - moves cursor one spacing to the left
\033[E - ?
\033[F - ?

\033[2K - erases everything written on line before this.

**(this could be useful for those who want more colors. The effect given by bold will give a color change effect)
