I DON'T actually need a response since I have a solution but the education would be nice.
Some history:
We've recently converted from alpha login ID's in the LDAP world to something called workday ID's(not my idea!). What this meant for us Linux admins was we had change everyone's alpha ID they'd used for years to a numeric ID. Not a big deal with the exception of a particular command we use to list jobs on the cluster. If I execute:
I now get the following:
The second field of the job ID line is the user's name now and we have been using ypcat to figure out who's who. A real pain, so I wrote a script (bjobs.sh) to replace the workday numeric ID with the 5th field from the ypcat passwd output.
Script:
Executed as:
While this works just fine I though I'd put this up here to see if anyone had a better way of doing this. Maybe a one line "bjobs -u all -m C7CRA" with awk and/or sed to grab that second field of the jobid line and replace it as the script does using the variable it gets from the ypcat passwd output. I tried various methods, got frustrated and simply went with what I knew would work. Thanks in advance for anyone willing to chime in.
Thanks for the response Scrutinizer. The line formatting was a good idea as it gave me something to go on with the other jobs like PEND and EXIT since they format a bit differently. I can now actually arrange the total output into something formatted better than the default.
I ended up using ypcat rather than getent since getent won't return user ID's that are all numeric. After some tinkering, getent proved to only return ID's that have at least one alpha character in them.
Hello RudiC,
Thanks for the response. The only issue with the single line command is it only works on the NIS master with the passwd file at /var/yp/files/passwd. All the other nodes in the cluster have the most basic passwd file. Which is why I felt forced to ypcat the passwd file for the 'real name'.
I had originally tried to assign a variable the value from ypcat on the awk command line but failed.
