Full Discussion: PATH environment variable
Operating Systems Linux Ubuntu PATH environment variable Post 302669425 by rupeshkp728 on Wednesday 11th of July 2012 02:50:46 AM

PATH environment variable
PATH is an environment variable.
When I open a terminal say terminal 1 and set some path in PATH variable it gets set which I can see using ech $PATH.

But when I open a new terminal say terminal 2 and fire echo $PATH why cannot I see the same output as seen in terminal terminal 1?
Why the path added to PATH variable using one terminal is not reflected in another terminal?

ul

ul(1)							      General Commands Manual							     ul(1)

NAME

       ul - Translates underlining for display on a terminal

SYNOPSIS

       ul [-i] [-t terminal] [file...]

       The ul command displays the named files (or standard input if none are given) with underlining shown as it would be on the printed page.

OPTIONS

       Causes  the  ul command to indicate underlining by a separate line containing appropriate - (dashes).  This is useful when you want to look
       at the underlining in formatted text output on a cathode ray tube (CRT) terminal.  Overrides the terminal kind specified  in  the  environ-
       ment.   The  terminfo  database is read to determine the appropriate sequences for underlining. If the terminal is incapable of underlining
       but is capable of a standout mode, then that mode is used instead. If the terminal can overstrike, or handles underlining automatically, ul
       acts like the cat command, simply displaying data to the screen.  If the terminal cannot underline, underlining is ignored.

DESCRIPTION

       The  ul command translates underscores to the sequence that indicates display underlining for the terminal in use, as specified by the TERM
       environment variable.

FILES

       Terminal information database.

       Commands:  col(1), colcrt(1), man(1), more(1)
