deprecation of echo

[Rusch, Daniel]

echo "hostaddress\tservice name\treturn code\tplugin output\n"

and 

echo -e "hostaddress\tservice name\treturn code\tplugin output\n"

are two different things

the -e interprets the backslashed escape character '\t'  without it echo
won't interpret it as a tab.  At tleast it didn't for me on RH 7.3

Subject: [Nagios-users] deprication of echo


This has been bugging me for quite sometime can someone please explain
it like im a 3-year old..
I agree echo -e is not portable but why use the e switch  in the first
place. if you surround the message in qoutes, echo works nicely, I
tested it on AIX redhat, and Solaris. Can anyone show me a instance
where  the output would not work? I have a couple  of custom scripts and
I use echo extensively throughout my configs and within my homegrown
scripts.  This just bugs me to no end becuase Echo was designed to be
just like a parrot, what you see is what you get.  it even works in NT
(though with NT the qoutes are displayed. IE:echo "this is a message"
comes out as "this is a message")

also if your using the -e switch, dont, -e is not available in all forms
of echo, enclose it in qoutes and like me, it should work fine..
feel free to educate this misguided individual(me) into the advantages
of using printf over echo  since it appears that Echo is actually more
portable than printf (printf dont work in NT, not that this matters but
if we are talking portability...)
and since its simple, why not keep it simple.)

just my three cents on the echo versus printf subject..

It may work, but it is not portable. That's why it was deprecated in the

distribution in favour of printf which is portable.
