# usb

Output connected usb storage device info.
|
|
Supports usb mass storage devices, including those with multiple partitions,
|
|
including LUKS partitions.

# Requirements
|
|
|
|
Dependencies: udev, python3, util-linux ( >= 2.23 )
|
|
|
|
Suggested: fonts-font-awesome
|
|
|
|
# Installation
|
|
The recommended i3blocks config is
|
|
|
|
```INI
|
|
[usb]
|
|
command=$SCRIPT_DIR/usb
|
|
markup=pango
|
|
signal=1
|
|
interval=10
|
|
#IGNORE_LIST=[]
|
|
#IGNORE_LIST=["sdd1", "mapper/sda1_crypt"]
|
|
#INFO_TEXT_COLOR=white
|
|
#MOUNTED_COLOR=green
|
|
#PLUGGED_COLOR=gray
|
|
#LOCKED_COLOR=gray
|
|
#UNLOCKED_NOT_MOUNTED_COLOR=yellow
|
|
#PARTITIONLESS_COLOR=red
|
|
#PARTITIONLESS_TEXT=no partitions
|
|
#SEPARATOR=<span color='gray'> | </span>
|
|
#LOCKED_INDICATOR=
|
|
#UNLOCKED_INDICATOR=
|
|
#READONLY_INDICATOR=ro
|
|
#TRUNCATE_FS_LABELS=[not set by default, accepts +/- integers]
|
|
```

To update the blocklet on plug/unplug device events you can add
|
|
|
|
SUBSYSTEMS=="usb", RUN+="/usr/bin/pkill -RTMIN+1 i3blocks"
|
|
|
|
in `/etc/udev/rules.d/70-persistent-usb.rules`.
|
|
You may need to create the file.
|
|
Then call
|
|
|
|
```ShellSession
|
|
sudo udevadm control --reload-rules
|
|
```
|
|
|
|
to activate the new rules.
|
|
If you do not care about updating the blocklet on plug/unplug,
|
|
the script works fine on just an interval and you can ignore the udev rule and
|
|
delete `signal=1` in the config.
|
|
|
|
Now restart your i3 in place with
|
|
|
|
```ShellSession
|
|
i3-msg restart
|
|
```
|
|
|
|
Try plugging in a usb device to make sure everything works.

# Configuration
|
|
|
|
The IGNORE_LIST variable, if set, must be a valid python representation of
|
|
a list of strings, e.g. `["sdd1", "mapper/sda1_crypt"]`.
|
|
Due to the way i3blocks parses config files, newlines are not allowed.
|
|
The strings are full device paths, with "/dev" optionally omitted.
|
|
For example, the previous "sdd1" is expanded to "/dev/sdd1" at runtime.
|
|
The list is safely parsed using ast.literal_eval, NOT eval.
|
|
|
|
If you decide not to install FontAwesome,
|
|
then you will probably want to change the `LOCKED_INDICATOR` and
|
|
`UNLOCKED_INDICATOR` variables, as these use unicode symbols provided by
|
|
FontAwesome (and not many other fonts).
|
|
You do not need to restart i3 after making a change to the config.
