Shell Programming and Scripting

VAR="${VAR// }" does not work in /bin/sh on Ubuntu, neither do arrays nor indirect references. You need to make sure the script is run with bash.

As Scrutinizer says use bash if you want arrays, etc. Put #!/bin/bash on the first line assuming you have bash installed on CentOS.

But let's get back to the array, With the code you are curently using anything before the "=" in the configfile is irrelevent: line 1 will go into array element #1 line 2 in #2, etc. Having said that you could simpify things by having your config file with just the values:

configfile:

Code:

Alpha Tech
test@hotmail.com
Password
abc@live.com
smtp.live.com:587

script:

Code:

#!/bin/bash
IFS=$'\n' Values=( "" $(< configfile) )
echo "Company=${Values[1]}"

Or keep support for named params and source the configfile eg:

configfile:

Code:

Company="Alpha Tech"
FromEmail="test@hotmail.com"
Password="Password"
ToEmail="abc@live.com"
Smtp="smtp.live.com:587"

script:

Code:

#!/bin/bash
. configfile
Values=( "" "$Company" "$FromEmail" "$Password" "$ToEmail" "$Smtp" )
echo "Company=${Values[1]}"
