I need for the case when evaluates to marybobsam .
I can find examples in bash shell, but I need dash.
Are you asking how to check for the substring "bob" in your input,
in POSIX sh? Use case, and a glob:
case $input in
*bob*) echo "Bob found." ;;
esac
case $(hostname) in
*bob*) echo "I must be a Bob." ;;
esac
Thank you. I was expecting an if...fi construct.
Is dash documented anywhere?
All I've found are pages saying that some "bashisms" do not work
in dash :<
I've no experience with bash (or any shell) and in any case I'm
constrained to using dash as I'm working with preseed.cfg .
