Java Environment Variables

1. The problem statement:

What is the mesg value set for your environment? If it is on, how would you turn off your current
session? How would you set it permanently?



3. The attempts at a solution :

Read Unix The textbook.
3rd chapter has many things like environment variables and ans setting value of a variable for our session or any subsequent session but nothing about "mesg" value.

I think its a typo cuz google also doesn't show any result about it.

also went through Operating System Concepts 8th edition

NAME
sb2-session - manage scratchbox2 sessions SYNOPSIS
sb2-session [COMMAND [PARAMS]] DESCRIPTION
sb2-session is used to create attachable scratchbox2 sessions. You can save session even when you haven't done '-S session' during sb2 startup. Note that you can give parameters to attach command which are passed verbatim to sb2. If there is only one session to attach, it is selected automatically. If no command is given, help text is printed. COMMANDS
help shows help text save saves current session list lists detached sb2 sessions delete SESSION deletes given session attach [SESSION [PARAMS]] attaches to a given session setenv VARIABLE VALUE store a value for an environment variable showenv show stored environment variables EXAMPLES
Basic usage is: [SB2 .. ] $ sb2-session save # save session [SB2 .. ] $ ^D # exit Later we can then attach to this session: % sb2-session attach If there are more than one saved session, then: % sb2-session list session.XXXX TARGET_ARM My Comment session.YYYY TARGET_ARM My Comment 2 session.ZZZZ TARGET_MIPS % sb2-session attach session.YYYY Here we pass '-eR' to sb2 and we only have one saved session: % sb2-session attach -- -eR '--' marks end of parameter list for sb2-session. setenv VARIABLE VALUE can be used to add environment variables, that will become active when a saved session is later taken into use (either by sb2-session attach or by sb2 -J). setenv VARIABLE VALUE does not change environment of sessions that are already active. showenv lists environment variable settings which have been stored with this tool. It does not show environment variables from other sources. SEE ALSO
