What does the Bash operator <<< (i.e. triple less than sign) mean?
bash, herestring, shell
Solution
It redirects the string to stdin of the command.
Variables assigned directly before the command in this way only take effect for the command process; the shell remains untouched.
Problem
What does the triple-less-than-sign bash operator, `<<<`, mean, as inside the following code block? ``` LINE="7.6.5.4" IFS=. read -a ARRAY <<< "$LINE" echo "$IFS" echo "${ARRAY[@]}" ``` Also, why does `$IFS` remain to be a space, not a period?
