I don't understand this AIX.
How do I do
sudo apt-get on AIX?
-bash-3.00$ sudo -bash: sudo: command not found -bash-3.00$ apt-get -bash: apt-get: command not found
Oh man, you are definitely going to have a very bad time.
You come from Ubuntu. Here you don't have
sudo, but you may have
su. Check it and if you do have it, this problem is solved.
AIX not having Advanced Packaging Tool framework support is not easily solvable. Take into account that if you ran fedora or CentOS you would not also have those, and you would have to front the software installation using selection by
yum, lower level rpm packaging handlers, or software build. Using AIX you most probably will have to face manual software builds.
apt is a Debian only application that was inherited by ubuntu. Having it work on AIX would be akin to trying to run yum on Ubuntu. There is no reason whatsoever this command would work
Unfortunately, it looks like AIX systems don't have a repository for its package manager at all - you will need to obtain AIX packages (which seem to be RPMs) or compile things yourself. As per the comment by wally, AIX has installp and the smitty install command. They do seem to use rpms, but rpms for linux distros are unlikely to work.
Aix uses it own software software system through the System Management Tool (a.k.a. SMiT).
There is limited support for RPM's but these have to be build for Aix.
Normal Linux RPM's won't work at all.
sudo is available (but not default) on AIX 5 and later (could be AIX 6, I'm not sure). But it needs to be setup by the system administrator. Normally it isn't used and you need "su" to elevate yourself to system admin.
AIX is not LINUX. It is a completely different OS and many things you take for granted on a Linux system are just not there or done by other software.
By the way: From that Python line in the comments I see you are on Aix version 4. That has been obsolete for years. Current version is 7, with extended support for 5.3 and 6 still available.
This guy has solved the yum / apt-get rpm package management issue on AIX, kind of:
You have to build your own local repository though. Maybe someone can grab his code ( rpmplus ) and get it to work with curl or wget or something similar. For now, it's the best thing we've got. Hopefully IBM will get their act together and make this functionality available in SUMA or make it a SMIT panel ( smitty rpminstall, please ).
