There are 2 simple options:
1. If the number of params are not too many just pass them on command line:
#/bin/bash
APPLICATION=$1
LOCALHOST=`hostname -s`
REMOTEHOST=$2
WEBDATA=$3
SQLUSER=$4
SQLPASS=$5
SQLDB=$6
# ---------------------------------------------
#run like this:
backup.sh appName remotehost webdataLocation usr pswd db
You name make them named params using the getopt . Google for more examples.
2. Use the file as you mentioned. Usually I would go with the property file syntax.
key=value
In this case you can parse the file like this. An except from one of my scripts:
#!/bin/bash
#
# Sets internal variables based on <config file> contents.
# $1 - <config file>
# returns nothing, sets all variables.
#
process_TC_config_file() {
_logecho "Entering _process_TC_config_file(): \$* = $*"
_logecho "TC_CONFIG_FILE=$TC_CONFIG_FILE"
local NEW_INPUT_FILE=$TC_DIR/new_config
cp $1 $NEW_INPUT_FILE
# remove leading spaces/tabs and comments
sed -i '/^$/d;s/^[ \t]+//g;/^#/d' $NEW_INPUT_FILE
# work around for "read". It returns non-zero for last line in file.
# So if the last line contains valid input it will be lost.
echo "" >> $NEW_INPUT_FILE
while read one_line
