Hello,

 

How do I go about finding out when last a file was accessed(Read)? We can find out when last it was written or modified but not read.

- We do not have Environment Manager enabled.

- We are on Linux Suse

- One Linux Suse server

 

thanks,

ls -ul filename

is the UNIX command to display the last access timestamp of a file.

Be aware that this might not really tell you much, as each complete backup will read the file.

And everytime someone uses sashelp.vtable or sashelp.vcolumn every table in every currently assigend library will be read.

Very useful. There is also the stat / istat commands to display the same information taken out from the filesystem  with the 3 three components of timestamp. Linux stat might offer some additonal functionality fbeing able to

customise the output sometimes, reducing the amount of information.

 

eg, istat command for AIX 7.1 (IBM Unix)

  • Date of the last i-node update ("physical storage information")
  • Date of the last file modification
  • Date of the last reference to the file  ("last access")
