in reply to RE (tilly) 3: Get default login environment
in thread Get default login environment

I downloaded this code but it doesn't work! When I try and use it the following error occurs -
syntax error at line 8, near "m/^(.*?)=((?:[^\n\\]|\\.| +\\\n)*)/gm ;"
The code to call this sub is also in a format that, novice that I am, I've not seen before -
%ENV = (%ENV, get_bash_login_env());
The ENV inside the brackets is throwing me. Is this the means by which the local (in the subroutine) %ENV is used to overwrite the existing %ENV? I've not seen this syntax before. Ronnie Cruickshank

    It was missing a closing bracket just before the ";" in that line. This works:

    sub get_login_env { local %ENV; my $shell = shift || (getpwuid($<))[8]; my $env = `echo env | perl -e 'exec {"$shell"} -sh'`; if (wantarray) { my @pieces = ($env =~ m/^(.*?)=((?:[^\n\\]|\\.|\\\n)*)/gm ); s/\\(.)/$1/g foreach @pieces; return @pieces; } else { return $env; } }

    Cheers, Sören
