condor_who
Display information about owners of jobs and jobs running on an execute machine
condor_who
[help options]
[address options]
[display options]
condor_who queries and displays information about the user that
owns the jobs running on a machine.
It is intended to be run on an execute machine.
The options that may be supplied to condor_who belong to three groups:
- Help options provide information about the condor_who
tool.
- Address options allow destination specification for query.
- Display options control the formatting and which of the
queried information to display.
At any time, only one help option and one address option
may be specified.
Any number of display options may be specified.
condor_who obtains its information about jobs by talking to
one or more condor_startd daemons.
So, condor_who must identify the command port of any condor_startd
daemons.
An address option provides this information.
If no address option is given on the command line,
then condor_who searches using this ordering:
- A defined value of the environment variable CONDOR_CONFIG
specifies the directory where log and address files are to be scanned
for needed information.
- With the aim of finding all condor_startd daemons,
condor_who utilizes the same algorithm it would using the
-allpids option.
The Linux ps or the Windows tasklist
program obtains all PIDs.
As Linux root or Windows administrator,
the Linux lsof or the Windows netstat identifies open
sockets and from there the PIDs of listen sockets.
Correlating the two lists of PIDs results in identifying the command ports of
all condor_startd daemons.
- -help
- (help option) Display usage information
- -diagnostic
- (help option) Display extra information
helpful for debugging
- -verbose
- (help option) Display PIDs and
addresses of daemons
- -address hostaddress
- (address option)
Identify the condor_startd host address to query
- -allpids
- (address option) Query all local
condor_startd daemons
- -logdir directoryname
- (address option)
Specifies the directory containing log and address files
that condor_who will scan to search
for command ports of condor_start daemons to query
- -pid PID
- (address option) Use the given PID
to identify the condor_startd daemon to query
- -long
- (display option) Display entire ClassAds
- -wide
- (display option) Displays fields without
truncating them in order to fit screen width
- -format fmt attr
- (display option) Display attribute
attr in format fmt.
To display the attribute or expression the format must contain a single
printf(3)-style conversion specifier.
Attributes must be from the resource ClassAd.
Expressions are ClassAd expressions and may
refer to attributes in the resource ClassAd.
If the attribute is not present in a given ClassAd and cannot
be parsed as an expression, then the
format option will be silently skipped.
The conversion specifier must match the type of the
attribute or expression.
%s is suitable for strings such as Name,
%d for integers such as LastHeardFrom,
and %f for floating point numbers such as LoadAvg.
%v identifies the type of the attribute,
and then prints the value in an appropriate format.
%V identifies the type of the attribute,
and then prints the value in an appropriate format as it would
appear in the -long format.
As an example, strings used with %V will have quote marks.
An incorrect format will result in undefined behavior.
Do not use more than one conversion specifier in a given
format. More than one conversion specifier will result
in undefined behavior. To output multiple attributes
repeat the -format option once for each desired
attribute.
Like printf(3)-style formats, one may include other
text that will be reproduced directly.
A format without any conversion specifiers may be specified,
but an attribute is still required.
Include
n to specify a line break.
- -autoformat[:tn,lVh] attr1 [attr2 ...]
- (display option) Display machine ClassAd attribute values
formatted in a default way according to their attribute types.
This option takes an arbitrary number of attribute names as arguments,
and prints out their values. It is like the -format option,
but no format strings are required.
It is assumed that no attribute names begin with a dash character,
so that the next word that begins with dash is the
start of the next option.
The autoformat option may be followed by a colon character
and formatting qualifiers:
t add a tab character before each field instead of
the default space character,
n add a newline character after each field,
, add a comma character after each field,
l label each field,
V use %V rather than %v for formatting,
h print headings before the first line of output.
The newline and comma characters may not be used together.
Example 1 Sample output from the local machine,
which is running a single Condor job.
Note that the output of the PROGRAM field will be truncated
to fit the display, similar to the artificial truncation shown in this
example output.

and it will exit with the value 1 (one) upon failure.
