Changing the format of qstat output

If you don’t mind using a different command, and don’t mind having it formatted in json, you can output qstat to json and use jq to process it.
This is what I used to get unique users in a queue:

[vstumpf@shecil ~]$ qstat
Job id            Name             User              Time Use S Queue
----------------  ---------------- ----------------  -------- - -----
1000066.shecil    STDIN            pbsuser           00:00:00 R workq
1000067.shecil    STDIN            vstumpf           00:00:00 R workq
1000068.shecil    STDIN            vstumpf           00:00:00 R workq
1000069.shecil    STDIN            vstumpf           00:00:00 R workq
1000070.shecil    STDIN            pbsuser                  0 Q workq
1000071.shecil    STDIN            pbsuser1                 0 Q workq
1000073.shecil    STDIN            pbsuser2                 0 Q exprq
[vstumpf@shecil ~]$ qstat -f -Fjson | jq '.Jobs | map(select(.queue == "workq") | .euser) | unique'
[
  "pbsuser",
  "pbsuser1",
  "vstumpf"
]
[vstumpf@shecil ~]$ qstat -f -Fjson | jq '.Jobs | map(select(.queue == "exprq") | .euser) | unique'
[
  "pbsuser2"
]
