How to install the lsof (LiSt Open Files) utility on AIX V5.3
Download the lsof
installation image (and Readme) from the AIX Web Download Pack Programs web page. Follow installation instructions in the Readme.
When first installed, lsof might fail with:
ibm:/ # lsof /home
lsof: FATAL: compiled for a kernel of 32 bit size.
The bit size of this kernel is 64.
ibm:/ #
The README.txt file included in lsof-4.7.tar.Z says:
The lsof fileset contains two lsof binaries "lsof" and "lsof64".
So use the appropriate binaries depending on the type of your kernel bits.
i.e use lsof for 32-bit kernel and lsof64 for 64 bit kernel.
So:
ibm:/ # lslpp -f lsof.base
