NAME

idevicesyslog - Relay syslog of a connected device.

SYNOPSIS

idevicesyslog [OPTIONS]

DESCRIPTION

Relay syslog of a connected device.

OPTIONS

-u, --udid UDID
target specific device by UDID
-n, --network
connect to network device
-x, --exit
exit when device disconnects
-d, --debug
enable communication debugging
-h, --help
prints usage information
-v, --version
prints version information.
--no-colors
disable colored output

FILTER OPTIONS

-m, --match STRING
only print messages that contain STRING

This option will set a filter to only printed log messages that contain the given string.

-t, --trigger STRING
start logging when matching STRING

When specified, logging will start as soon as a log messages is encountered that contains the given string. See also -T, --untrigger. Other filters are still applied but obviously filtered messages are only printed after logging has started.

-T, --untrigger STRING
stop logging when matching STRING

When specified logging will halt as soon as a log message is encountered that contains the given string. See also -t, --trigger. Other filters are still applied but obviously filtered messages are only printed before logging stops.

NOTE: If no --trigger is given, idevicesyslog will exit after a matching log message was encountered.

-p, --process PROCESS
only print messages from matching process(es)

PROCESS is a string that can either be a numeric pid or a process name. It also supports multiple process names or pids in one string, separated by | (make sure to use quotes!).

-e, --exclude PROCESS
print all messages except matching process(es)

PROCESS is a string that can either be a numeric pid or a process name. It also supports multiple process names or pids in one string, separated by | (make sure to use quotes!).

-q, --quiet
set a filter to exclude common noisy processes

Since the syslog can be quite noisy, this quick command line switch allows to silence out a predefined set of commonly known processes. The list of processes that are silenced can be retrieved with --quiet-list.

--quiet-list
prints the list of processes for --quiet and exits
-k, --kernel
only print kernel messages

This is actually equivalent to passing --process kernel with the exception that it can be used with --quiet to silence out the noisy process but still get all the kernel log messages.

-K, --no-kernel
suppress kernel messages

This is equivalent to passing --exclude kernel.

EXAMPLES

idevicesyslog -u 00008030-0000111ABC000DEF
Relay syslog of device with UDID 00008030-0000111ABC000DEF.
idevicesyslog -x
Relay syslog of device and exit when the device is unplugged.
idevicesyslog -m '####' -e 'identityservicesd' -K
Only print log messages that contain the string #### and do NOT originate from identityservicesd or the kernel.
idevicesyslog -p MyApp -p ReportCrash
Only print log messages from the process named 'MyApp' and 'ReportCrash'.
idevicesyslog -p 'MyApp|ReportCrash'
Same as previous example with different syntax.
idevicesyslog -e 'backboardd|CommCenter|mDNSResponder'
Suppress log messages from backboardd, CommCenter, and mDNSResponder.
idevicesyslog -q -k
Suppress log messages from common noisy processes, but DO print kernel log messages.
idevicesyslog -K
Suppress log messages from kernel, but print everything else
idevicesyslog -t 'backlight on' -T 'backlight off' -q
Start logging when the device turns on backlight and stop logging when it turns backlight off, and suppress noisy processes
