Hello
A couple of weeks ago, I added a user to an AIX 5.3 system.
I go to add one today, and it appears that when creating a user in smit, I cannot see any groups.
No primary groups
No Group set
No Admin Groups
The /etc/group and etc/secuity/group files seem to be intact.
I did... (4 Replies)
What's the difference between groups and id-a.
We're using LDAP, rather than NIS+, and a user has been added to an extra Unix group. The groups command shows the new group but id -a doesn't!
Why would this be? (5 Replies)
Must I be in a group? I am using Ubuntu and am the only user on my PC. I know how to change groups but do not see a way to not be in a group. Any help would be appreciated. (2 Replies)
Hi
I see that I can use umask to set the default permissions on files created by a script like so -
umask u=rwx,g=rwx,o=
So that would grant rwx to the user and group.
My question is how do I control the group this applies to?
I want a script to create files under... (3 Replies)
I have a Solaris 10 system inherited from several previous admins. While trying to decipher a permissions issue, I ran "grpck" and it reported a ton of errors. Among them were these:
1. group name too long
2. group name contains illegal characters (special chars or caps)
3. group membership... (2 Replies)

unbuffer
UNBUFFER(1) General Commands Manual UNBUFFER(1)NAME
unbuffer - unbuffer output
SYNOPSIS
unbuffer program [ args ]
INTRODUCTION
unbuffer disables the output buffering that occurs when program output is redirected from non-interactive programs. For example, suppose
you are watching the output from a fifo by running it through od and then more.
od -c /tmp/fifo | more
You will not see anything until a full page of output has been produced.
You can disable this automatic buffering as follows:
unbuffer od -c /tmp/fifo | more
Normally, unbuffer does not read from stdin. This simplifies use of unbuffer in some situations. To use unbuffer in a pipeline, use the
-p flag. Example:
process1 | unbuffer -p process2 | process3
CAVEATS
unbuffer -p may appear to work incorrectly if a process feeding input to unbuffer exits. Consider:
process1 | unbuffer -p process2 | process3
If process1 exits, process2 may not yet have finished. It is impossible for unbuffer to know long to wait for process2 and process2 may
not ever finish, for example, if it is a filter. For expediency, unbuffer simply exits when it encounters an EOF from either its input or
process2.
In order to have a version of unbuffer that worked in all situations, an oracle would be necessary. If you want an application-specific
solution, workarounds or hand-coded Expect may be more suitable. For example, the following example shows how to allow grep to finish pro-
cessing when the cat before it finishes first. Using cat to feed grep would never require unbuffer in real life. It is merely a place-
holder for some imaginary process that may or may not finish. Similarly, the final cat at the end of the pipeline is also a placeholder
for another process.
$ cat /tmp/abcdef.log | grep abc | cat
abcdef
xxxabc defxxx
$ cat /tmp/abcdef.log | unbuffer grep abc | cat
$ (cat /tmp/abcdef.log ; sleep 1) | unbuffer grep abc | cat
abcdef
xxxabc defxxx
$
BUGS
The man page is longer than the program.
