Posted by bhavik (bhavik), 7 December 2007Hi Folks,
I wrote expect script in(unix) which, I want to access parent shell's env variable like $HOME , $PWD ......... and I dont hav any clue to access it ..... means how to import them into my script .

plz help me out......
thanks in advance.
Posted by admin (Graham Ellis), 7 December 2007The env array holds your environment variables:
% array names env
INFOPATH MANPATH HOME LOGNAME PWD TERM_PROGRAM __CF_USER_TEXT_ENCODING TERM SHELL SECURITYSESSIONID SHLVL OLDPWD TERM_PROGRAM_VERSION PATH _ PERL5LIB USER
% puts $env(HOME)
% puts $env(PWD)
% puts $env(SHELL)
and indeed they are accessible by the expect script - see above. There is no need for you to specially import them, but they do need to be exported from the parent shell so that they are available to you ...
