6 Shell Script Examples
The following pages contain complete shell scripts, which are customized for the most common
applications.
Shell Scripting Tips
• Include #!/bin/mish –x to debug your scripts. Run via Telnet.
• A very useful program for fetching or uploading scripts to the product, Ultra Edit, can be
downloaded from http://www.ultraedit.com/
6.1 The configuration file
The configuration file is located in the /etc/applications directory. At the beginning of
each script, a configuration file is sourced, to identify the variables inside.
This file allows you to use the same scripts, but with different parameters for each of them. A
typical example is to upload files to a particular ftp-server for each camera. You would then
create different config files and call the script with the correct parameters.
# Read the config file
. /etc/applications/config_$1
# Read the optional config file
if [ -e /etc/applications/pre_config_$1 ]; then
. /etc/applications/pre_config_$1
fi
# --- General camera parameters ---
# The index of the name(s) of the buffer(s) started
sources="1"
# The format of the images specified to be taken according to HTTP-API
image_format="fullsize"
# The name to be given to the local file, excluding the extension
file_format="snapshot"
# Number of pre alarm images to be taken
pre=2
# Number of post alarm images to be taken
post=2
# Delay between pre-images in milliseconds
predelay=1000
# Delay between post-images in milliseconds
postdelay=1000
# Delay between image taken
delay=2000
# The time in seconds to stay in the script. A value of -1 means
# indefinitely
time=10
# The index of the name(s) of the buffer(s) started for sequential
# images
