reach(1)

NAME

reach - wrapper around the ping command

SYNOPSIS

reach hostname | ip

DESCRIPTION

The reach command is a simple wrapper around ping and ping6. reach has a configuration file to adjust its behavior. Benefits:

• Check exit status to determine reachability of a host or IP. The exit status of ping or ping6 is passed through as the exit status of reach.

• No output to /dev/stdout

• Errors go to /dev/stderr

• Reduces complexity of other scripts

OPTIONS

None.

ENVIRONMENT

PING_TMOUT

The number of seconds to wait for a response from the target host.

EXAMPLE

for x in $(seq 1 5); do
  echo -n "server${x}.example.com: "
  reach server${x}.example.com || { echo; continue; }
  ssh server${x}.example.com "uptime"
done
