The Linux Manuals (man pages) document is an important part of Linux documents. Linux Manuals are organized as several sections. Each section has a group of commands for a specific area in Linux usage, administration or development.
NAME tracker-miner-fs-3 – Used to crawl the file system to mine data. SYNOPSIS tracker-miner-fs-3 [OPTION…] DESCRIPTION tracker-miner-fs-3 is not supposed to be run by the user since it is started by its .desktop file when the user logs in. It can also be started manually of course for debugging purposes. You can not run more…
NAME tracker-info – Retrieve all information available for a certain file. SYNOPSIS tracker info [options…] <file1> [[file2] …] DESCRIPTION tracker info asks for all the known metadata available for the given file. Multiple file arguments can be provided to retrieve information about multiple files. The file argument can be either a local path or a…
NAME tracker-index – List, pause, resume and command data miners indexing content SYNOPSIS tracker index– reindex – mime – type<mime1>[[-m[mime2]]…] tracker index– file<file1> [[file2]…] tracker index– import <file1> [[file2]…] tracker index– backup<file> | –restore<file> DESCRIPTION This command perform actions on the current index. The "index" holds a snapshot of the working tree in a database….
NAME tracker-import – Imports Turtle file data into the database SYNOPSIS tracker-import FILE DESCRIPTION tracker-import allows data to be imported to the database by providing files with Turtle content. Multiple FILE arguments can be provided to import data from multiple files. The FILE argument can be either a local path or a URI. It also…
NAME tracker-extract – Extract metadata from a file. SYNOPSYS tracker extract FILE DESCRIPTION tracker extract reads the file provided and extracts any metadata it can from this file, then displays the metadata on standard output. The metadata is displayed as a SPARQL update command, that can be run against a SPARQL endpoint to update its…
NAME tracker-daemon – Start, stop, restart and list daemons responsible for indexing content SYNOPSIS tracker daemon [options…] tracker daemon -s | -t [daemons] | -k [daemons] | -l tracker daemon -f | -w [ontology] tracker daemon –miner <miner> –pause[-for-process] <reason> tracker daemon –miner <miner> –resume <cookie> DESCRIPTION Tracker has many components to it including a…
NAME tracker-control – Manage Tracker processes and data SYNOPSIS tracker-control [OPTION…] DESCRIPTION tracker-control manages and checks status of all Tracker processes and data. Controls Tracker both at process level, and at entity level (store, miners). To start or stop miners, you can use –start. The store is started automatically by the D-Bus calls from the…
GNU Network Utilities NAME traceroute – trace the route to a host SYNOPSIS traceroute [option … ] host DESCRIPTION Print the route packets trace to network host OPTIONS -f , -first-hop = start Set the initial hop distance, that is the time-to-live. -g , -gateways = gates List of gateways for loose source routing. -I…
NAME trace-cmd – interacts with Ftrace Linux kernel internal tracer SYNOPSIS trace-cmd COMMAND [OPTIONS] DESCRIPTION The trace-cmd(1) command interacts with the Ftrace tracer that is built inside the Linux kernel. It interfaces with the Ftrace specific files found in the debugfs file system under the tracing directory. A COMMAND must be specified to tell trace-cmd…
NAME trace-cmd-stream – stream a trace to stdout as it is happening SYNOPSIS trace-cmd stream [OPTIONS] [command] DESCRIPTION The trace-cmd(1) stream will start tracing just like trace-cmd-record(1), except it will not record to a file and instead it will read the binary buffer as it is happening, convert it to a human readable format and…
NAME trace-cmd-stop – stop the Ftrace Linux kernel tracer from writing to the ring buffer. SYNOPSIS trace-cmd stop [OPTIONS] DESCRIPTION The trace-cmd(1) stop is a complement to trace-cmd-start(1). This will disable Ftrace from writing to the ring buffer. This does not stop the overhead that the tracing may incur. Only the updating of the ring…
NAME trace-cmd-stat – show the status of the tracing (ftrace) system SYNOPSIS trace-cmd stat DESCRIPTION The trace-cmd(1) stat displays the various status of the tracing (ftrace) system. The status that it shows is: Tracer: if one of the tracers (like function_graph) is active. Otherwise nothing is displayed. Events: Lists the events that are enable. Event…
NAME trace-cmd-start – start the Ftrace Linux kernel tracer without recording SYNOPSIS trace-cmd start [OPTIONS] DESCRIPTION The trace-cmd(1) start enables all the Ftrace tracing the same way trace-cmd-record(1) does. The difference is that it does not run threads to create a trace.dat file. This is useful just to enable Ftrace and you are only interested…
NAME trace-cmd-stack – read, enable or disable Ftrace Linux kernel stack tracing. SYNOPSIS trace-cmd stack DESCRIPTION The trace-cmd(1) stack enables the Ftrace stack tracer within the kernel. The stack tracer enables the function tracer and at each function call within the kernel, the stack is checked. When a new maximum usage stack is discovered, it…
NAME trace-cmd-split – split a trace.dat file into smaller files SYNOPSIS trace-cmd split [OPTIONS] [start-time [end-time]] DESCRIPTION The trace-cmd(1) split is used to break up a trace.dat into small files. The start-time specifies where the new file will start at. Using trace-cmd-report(1) and copying the time stamp given at a particular event, can be used…
NAME trace-cmd-snapshot – take, reset, free, or show a Ftrace kernel snapshot SYNOPSIS trace-cmd snapshot [OPTIONS] DESCRIPTION The trace-cmd(1) snapshot controls or displays the Ftrace Linux kernel snapshot feature (if the kernel supports it). This is useful to "freeze" an instance of a live trace but without stopping the trace. trace – cmd start -…
NAME trace-cmd-show – show the contents of the Ftrace Linux kernel tracing buffer. SYNOPSIS trace-cmd show [OPTIONS] DESCRIPTION The trace-cmd(1) show displays the contents of one of the Ftrace Linux kernel tracing files: trace, snapshot, or trace_pipe. It is basically the equivalent of doing: cat /sys/kernel/debug/tracing/trace OPTIONS -p Instead of displaying the contents of the…
NAME trace-cmd-restore – restore a failed trace record SYNOPSIS trace-cmd restore [OPTIONS] [command] cpu-file [cpu-file …] DESCRIPTION The trace-cmd(1) restore command will restore a crashed trace-cmd-record(1) file. If for some reason a trace-cmd record fails, it will leave a the per-cpu data files and not create the final trace.dat file. The trace-cmd restore will append…
NAME trace-cmd-reset – turn off all Ftrace tracing to bring back full performance SYNOPSIS trace-cmd reset [OPTIONS] DESCRIPTION The trace-cmd(1) reset command turns off all tracing of Ftrace. This will bring back the performance of the system before tracing was enabled. This is necessary since trace-cmd-record(1), trace-cmd-stop(1) and trace-cmd-extract(1) do not disable the tracer, event…
NAME trace-cmd-report – show in ASCII a trace created by trace-cmd record SYNOPSIS trace-cmd report [OPTIONS] [input-file] DESCRIPTION The trace-cmd(1) report command will output a human readable report of a trace created by trace-cmd record. OPTIONS -i input-file By default, trace-cmd report will read the file trace.dat. But the -i option open up the given…
