changing primary group within a script. 1

[exsnafu]

I have a user who needs to change which group files get written out as several times within a script.

at first we looked at using setgroups and newgrp but those spawn a new shell and thus break the script.

i know at the end of the day we can just do a chgrp as a second operation for whatever files are being written but i'm wondering if there is some clever way to make this work in aix? on solaris i can use here docs with newgrp but seems the aix version isn't as accommodating.

As a work around what about using a sudo command running as a different user that you can create with the correct group.

Just a suggestion.

If there's a mapping between the file group name and the directory it ends up in then use the suid bit on the directory.

For example

mkdir -m2777 test_dir
chown user:test_grp test_dir

Any files created in test_dir will have test_grp group ownership.
