I am modifying an existing script and it has the following line:
export SomeEnvVar=`echo ${SomeLocalVar}`
Why wouldn't it just read:
export SomeEnvVar=${SomeLocalVar}
Is there some reason to use echo instead of a direct assignment? :confused: (2 Replies)

tping
TPING(1) LAM COMMANDS TPING(1)NAME
tping - Send echo messages to LAM nodes.
SYNOPSIS
tping [-hv] [-c count] [-d delay] [-l length] nodes
OPTIONS -h Print the command help menu.
-v Turn OFF verbose mode.
-c count Send count messages.
-d delay Delay delay seconds between each message.
-l length Each message is length bytes long.
DESCRIPTION
The tping command sends messages to, and collects replies from, a list of nodes, via the LAM echo server. It is similar to the UNIX
ping(8) command, and is used as a quick diagnosis of the LAM network.
Unless options are specified, tping sends a 1 byte message an infinite number of times, displaying the roundtrip time of each message as it
completes, with a delay of 1 second between roundtrips. After the loop is broken (with keyboard interrupt, eg: ^C), tping prints statis-
tics about all roundtrip messages.
EXAMPLES
tping h
Echo messages to the local node.
tping -v n7 -l 1000 -c 10
Echo 1000 byte messages to node 7. Stay silent while working. Stop after 10 roundtrips and report statistics.
BUGS
There is no built-in timeout and tping will wait forever to receive an echo. If no echo is received, due to a dead link or node, tping
hangs. Stop the process with a keyboard suspend signal (eg: ^Z) and terminate LAM with lamhalt(1) or lamwipe(1) (although the use of
lamwipe(1) is deprecated).
