[ID 20000121.005] System command starting with environment variable on HP-UX

[Doug Wilson <dougw@safeguard.net>]

Reply-To: dougw@safeguard.net

This is a bug report for perl from dougw@safeguard.net,
generated with the help of perlbug 1.26 running under perl 5.00503.


-----------------------------------------------------------------
A non zero status is returned from the
system() function when the supplied command
begins with an environment variable setting
where the environment variable contains an
underscore or a digit. such as:

system('tmp_junk=5 ls') and die "Error:$!";
or:
system('tmp_junk1=5 ls') and die "Error:$!";

Even though such a command will work from the command
line and return a successful status of zero e.g., the
following works on the command line (and outputs
the results from ls):

tmp_junk=5 ls
or:
sh -c "tmp_junk=5 ls"
