"Conky是一款开源的轻量级系统监视工具，主要在Linux环境中使用，用于在桌面上显示系统状态信息，如CPU温度、内存使用情况、网络流量等。它支持自定义显示内容和样式，是Linux桌面美化的重要组件。" 在Conky的语法中，用户可以使用各种变量来获取和展示系统信息。以下是一些重要的Conky变量及其解释： 1. **acpiacadapter**: 这个变量用于获取ACPI（高级配置和电源接口）适配器的状态。在Linux系统中，它会查找`/sys/class/power_supply`目录下的子文件夹，通常为"AC"或"ADP1"，来获取电源适配器的状态信息。 2. **acpifan**: 用于显示ACPI风扇状态，可以帮助监控系统的散热情况。 3. **acpitemp**: 提供当前CPU的温度，以摄氏度为单位。 4. **addr**: 显示指定网络接口的IP地址，如果没有分配地址，则显示"NoAddress"。 5. **addrs**: 类似于`addr`，但可显示接口的所有IP地址，仅适用于Linux系统。 6. **adt746xcpu**: 从therm_adt746x模块获取CPU温度。 7. **adt746xfan**: 获取therm_adt746x模块中的风扇速度信息，帮助监控风扇性能。 8. **alignc**: 将文本居中对齐，参数`num`是可选的，用于调整对齐方式。 9. **alignr**: 将文本右对齐，`num`参数决定右边距。 10. **apcupsd**系列变量：这些与apcupsd（一个UPS管理守护进程）关联，提供UPS的连接信息、电池容量、最后切换到电池的原因、输入电压、负载百分比等，有助于监控UPS的状态。 11. **apcupsd_loadbar**和**apcupsd_loadgauge**: 这两个变量用于创建显示当前负载的条形图或仪表盘，提供可视化展示系统负载。以上只是Conky语法中的一部分，实际上还有许多其他变量和功能，比如显示内存、硬盘使用情况、网络流量、系统时间等。通过组合和自定义这些变量，用户可以创建出个性化的系统监视面板，以满足不同的需求和美化桌面的效果。在配置Conky时，了解并熟练运用这些变量是至关重要的，这将帮助你更好地监控和理解你的Linux系统。

entropy_poolsize

Total size of system entropy pool for crypto freaks

eval string

Evaluates given string according to the rules of TEXT

interpretation, i.e. parsing any contained text object specifications

into their output, any occuring '$$' into a single '$' and so on. The

output is then being parsed again.

eve

api_userid api_key

character_id

Fetches your currently training skill from the Eve Online API

servers (http://www.eve-online.com/) and displays the skill along

with the remaining training time.

exec command

Executes a shell command and displays the output in conky.

warning: this takes a lot more resources than other variables. I'd

recommend coding wanted behaviour in C and posting a patch.

execbar command

Same as exec, except if the first value return is a value between 0-

100, it will use that number for a bar. The size for bars can be

controlled via the default_bar_size config setting.

execgauge command

Same as exec, except if the first value returned is a value between

0-100, it will use that number for a gauge. The size for gauges can

be controlled via the default_gauge_size config setting.

execgraph (-t) (-l) command

Same as execbar, but graphs values. Uses a logaritmic scale when

the log option (-l switch) is given (to see small numbers). Values

still have to be between 0 and 100. The size for graphs can be

controlled via the default_graph_size config setting. Takes the

switch '-t' to use a temperature gradient, which makes the gradient

values change depending on the amplitude of a particular graph

value (try it and see). If -t or -l is your first argument, you may

need to preceed it by a space (' ').

execi interval command

Same as exec but with specific interval. Interval can't be less than

update_interval in configuration. See also $texeci

execibar interval command

Same as execbar, except with an interval

execigauge interval command

Same as execgauge, but takes an interval arg and gauges values.

execigraph interval (-t) (-l) command

Same as execgraph, but takes an interval arg and graphs values. If -

t or -l is your first argument, you may need to preceed it by a space

(' ').

execp command

Executes a shell command and displays the output in conky.

warning: this takes a lot more resources than other variables. I'd

recommend coding wanted behaviour in C and posting a patch.

This differs from $exec in that it parses the output of the command,

so you can insert things like ${color red}hi!${color} in your script

and have it correctly parsed by Conky. Caveats: Conky parses and

evaluates the output of $execp every time Conky loops, and then

destroys all the objects. If you try to use anything like $execi

within an $execp statement, it will functionally run at the same

interval that the $execp statement runs, as it is created and

destroyed at every interval.

execpi interval command

Same as execp but with specific interval. Interval can't be less than

update_interval in configuration. Note that the output from the

$execpi command is still parsed and evaluated at every interval.

flagged_mails (maildir) Number of mails marked as flagged in the specified mailbox or

mail spool if not. Only maildir type mailboxes are supported, mbox

type will return -1.
