Pass hotname from command
I have a problem, which is,
I have servers as
$hostname : Serverxxd
$hostname : Serverxxs
$hostname : Serverxxl
$hostname : Serverxxp
d=dev, s=sit, l=stg, p=prd
The packages will be in all the boxes and my script contains $ENV which I should be
getting from 'hostname'
I am not able to determine how I could look for the last letter in hostname and use it in script to call the ENV variable.

Please help/advise
Thanks
Chiru

One way --
Code:
lastletter=$(expr substr $hostname $(expr length $hostname) 1)

question
Glenn,

I got a small question. How do you assign variable value with : here. What's the significance here.

Quote:
$hostname : Serverxxd
$hostname : Serverxxs
$hostname : Serverxxl
$hostname : Serverxxp
could you ever assign a varialbe value with :

Please let me know

I think the original poster was just defining in non-programming terms what the $hostname variable could be. I don't believe the ":" has any significance beyond that.
