+/* TODO: set -e
+Exit if pipe, list, or compound command exits with a non-zero status.
+Shell does not exit if failed command is part of condition in
+if/while, part of && or || list except the last command, any command
+in a pipe but the last, or if the command's return value is being
+inverted with !. If a compound command other than a subshell returns a
+non-zero status because a command failed while -e was being ignored, the
+shell does not exit. A trap on ERR, if set, is executed before the shell
+exits [ERR is a bashism].
+
+If a compound command or function executes in a context where -e is
+ignored, none of the commands executed within are affected by the -e
+setting. If a compound command or function sets -e while executing in a
+context where -e is ignored, that setting does not have any effect until
+the compound command or the command containing the function call completes.
