Hello. I saw this in a shell script but don't know what it mean:
...
read _ANSWER
:${_ANSWER:=$DEFAULT}
...
What's the meaning of read and how to use it? And the same question
about the use of ":" and ":="? What's the difference between ":="
and simply "="? Can someone explain?
Thanks in advance.James _______________________________________________ Redhat-list mailing list [EMAIL PROTECTED] https://listman.redhat.com/mailman/listinfo/redhat-list
