Since bash is the more common scripting language and shell today I
thought I'd include some good helpful/starting resources

Shell scripting has nearly endless possibilities and are often used for things like automated backups


Just a few tips for string tests:

[code:1:8dee9e99e1]if [ -z str ] [/code:1:8dee9e99e1]
Will test to see if the string 'str' is NULL


To test if a string is not null then it's just
[code:1:df692c1fea]
if [ -n $variableorstring ]; then
echo "somecode and message here"
fi
[/code:1:df692c1fea]
