Luckily, I only need to log in to such systems (setup byIBM GTS, I believe) on rare occasions. It is unbelievable how AIX kept stuck in the 90s. And really, the number of filesystems on these machines is astonishing. I think I have seen more than 30 filesystems. More than 20 is apparently not unusual.Oh, I know about -h (-g doesn't work on this system (6.0.7));That was my fault. I knew -m works and suspected -g would display gigabytes. It doesn't.
Check out the "-B" option. It handles all that sillyness with remarkable elegance... (For example, "-B1MB" gives sizes in Megabytes [10^6 bytes]; "-B1T" gives sizes in Tebibytes [2^40 bytes])
I just prefer the slightly-more-detailed information when showing the space used as 1K blocks.Yes, sometimes that makes it easier to compare the numbers.Seriously, you should really look into LVM. It provides way more flexibility than DOS partitions for setups like yours.I've heard about LVM but really don't know that much about it. I'lllook more into it and see what it's all about. Thanks for the suggestion.You will not regret it.
LVM has the added advantage over traditional partitioning methods that it elegantly handles devices with capacities over 2TiB [2*2^40 bytes]. Most partitioning methods that originated before Y2K have 32 bit fields for block numbers. And 2^32*512 bytes = 2TiB .
