bits
usage: bits.py [-h] [-m | -b | -l | -L] MASK_OR_LIST [MASK_OR_LIST ...]
Convert a bit list into a hex mask or the other way around.
positional arguments:
MASK_OR_LIST A set of bits specified as a hexadecimal mask value (e.g.
0xeec2) or as a comma-separated list of bit IDs.
Consecutive ids can be compressed as ranges (e.g.
5,6,7,8,9,10 --> 5-10). By default all will be OR'ed
together. A specific group can be XOR'ed by prefixing it
with ^ or AND'ed by prefixing it with &.
options:
-h, --help show this help message and exit
mode:
-m, --mask Print the combined args as a hexadecimal mask value
(default).
-b, --bit Print the combined args as a bit mask value.
-l, --list Print the combined args as a list of bit IDs. Consecutive
IDs are compressed as ranges.
-L, --list-full Print the combined args as a list of bit IDs. Consecutive
IDs are *NOT* compressed as ranges.
Examples:
$ bits -m 4,5-8 16,30
0x400101f0
$ bits -l 0xeec2
1,6,7,9-11,13-15
$ bits -b 4,5-8 16,30
0b100_0000_0000_0001_0000_0001_1111_0000
irqstat
usage: irqstat.py [-h] [-r ROOT] [-c CPU_RANGE_OR_MASK] [-i IRQ] [-n] [-s]
[-z] [-e]
Display linux interrupts information.
options:
-h, --help show this help message and exit
-r ROOT, --root ROOT Root dir used to determine path to /proc (default /).
-c CPU_RANGE_OR_MASK, --cpu CPU_RANGE_OR_MASK
CPUs specified as an hexadecimal mask values (e.g.
0xeec2) or as a comma-separated list of IDs.
Consecutive IDs can be compressed as ranges (e.g.
5,6,7,8,9,10 --> 5-10). Can be used multiple times.
-i IRQ, --irq IRQ Only show this IRQ. Can be used multiple times.
Special values are HARD (for numbered hardware IRQs),
SOFT (for unnumbered software interrupts and
exceptions) and ALL (for all IRQs and exceptions). By
default, only numbered hardware IRQs are displayed.
-n, --num-per-cpu Display the number of bound IRQs per CPU.
-s, --stats Display interrupt counts.
-z, --display-zeroes Also show -s/--stats with 0 values.
-e, --exact Display exact stats values.
Examples:
$ irqstat -sc 0x3

usage: netgraph.py [-h] [-2] [-4] [-6] [-l]
Convert linux networking configuration to a DOT graph. The output can be piped
to dot to convert it to SVG or other formats. Example:
netgraph.py | dot -Tsvg > net.svg
System dependencies: iproute2, ethtool
options:
-h, --help show this help message and exit
-2, --l2-addresses Display mac addresses.
-4, --ipv4-addresses Display IPv4 addresses.
-6, --ipv6-addresses Display IPv6 addresses.
-l, --local Display loopback interfaces and local addresses.
Example:
$ netgraph -4

procstat
usage: procstat [-h] [-r ROOT] [-e] PID [PID ...]
Display process statistics: CPU/NUMA affinity, context switches (voluntary and
non-voluntary) and thread names.
positional arguments:
PID Process ID for which to display statistics.
options:
-h, --help show this help message and exit
-r ROOT, --root ROOT Root dir used to determine path to /proc (default /).
-e, --exact Display exact stats values.
Examples:
$ procstat $(pidof br)

systar
usage: systar [-h] [-v] [-f FILE] PATH [PATH ...]
Create gzipped tar archives of sysfs devfs folders. Properly handling file
sizes without errors.
positional arguments:
PATH Path to include into archive (folder contents are
included recursively).
options:
-h, --help show this help message and exit
-v, --verbose Print files and dirs on stderr as they are included in
the archive.
-f FILE, --file FILE Output file to create. By default, gzipped tar archive
is written to stdout.
Example:
$ tar -zcvf cpu-topo.tgz /sys/devices/system/cpu/cpu*/topology
/sys/devices/system/cpu/cpu0/topology/
/sys/devices/system/cpu/cpu0/topology/cluster_cpus
tar: /sys/devices/system/cpu/cpu0/topology/cluster_cpus: File shrank by 4093 bytes; padding with zeros
/sys/devices/system/cpu/cpu0/topology/die_id
tar: /sys/devices/system/cpu/cpu0/topology/die_id: File shrank by 4094 bytes; padding with zeros
/sys/devices/system/cpu/cpu0/topology/cluster_cpus_list
tar: /sys/devices/system/cpu/cpu0/topology/cluster_cpus_list: File shrank by 28668 bytes; padding with zeros
/sys/devices/system/cpu/cpu0/topology/physical_package_id
tar: /sys/devices/system/cpu/cpu0/topology/physical_package_id: File shrank by 4094 bytes; padding with zeros
