How to use variable set from terminal in TCL ?

[tusharv]

Hi All,

I have set one variable PROJECT_PATH.
So How can I use this variable in any TCL file ?

Thanks,
Tushar

I *assume* here, that you are talking about setting an environment variable - if so,
it will live in tcl's environment array.

From an interactive tclsh:



puts $env(PROJECT_PATH)


To get the entire contents of what tcl knows as the environment array:



parry env


Hope this answers your question?

Hi stevescripts,

Yes Your ans satisfies my need.
And regarding your second code
parry env I think It should be
parray env

Thanks,
