Hi,
In ksh versions at least since ksh-20060214 newgrp is a ksh builtin
on linux.
When you do a newgrp to a groupname that doesn't exist or a
group that you don't belong to, your shell exits.
When I look in src/cmd/ksh93/data/builtins.c, I know find
#if _bin_newgrp || _usr_bin_newgrp
"newgrp", NV_BLTIN|BLT_ENV|BLT_SPC, Bltin(login),
#endif /* _bin_newgrp || _usr_bin_newgrp */
and in earlier versions
#ifdef _bin_newgrp
"newgrp", NV_BLTIN|BLT_ENV|BLT_SPC, Bltin(login),
#endif /* _bin_newgrp */
Since on RedHat Linux newgrp is in /usr/bin, the new test makes
newgrp a builtin with the newer versions of ksh, while in older
versions newgrp isn't configured to be a builtin.
Can this be the source of our problem?
regards,
