/*
|
||
* HOWTO Extend the top 'inspect' functionality:
|
||
*
|
||
* To exploit the 'Y' interactive command, one must add entries to
|
||
* the top personal configuration file. Such entries simply reflect
|
||
* a file to be read or command/pipeline to be executed whose results
|
||
* will then be displayed in a separate scrollable window.
|
||
*
|
||
* Entries beginning with a '#' character are ignored, regardless of
|
||
* content. Otherwise they consist of the following 3 elements, each
|
||
* of which must be separated by a tab character (thus 2 '\t' total):
|
||
* type: literal 'file' or 'pipe'
|
||
* name: selection shown on the Inspect screen
|
||
* fmts: string representing a path or command
|
||
*
|
||
* The two types of Inspect entries are not interchangeable.
|
||
* Those designated 'file' will be accessed using fopen/fread and must
|
||
* reference a single file in the 'fmts' element. Entries specifying
|
||
* 'pipe' will employ popen/fread, their 'fmts' element could contain
|
||
* many pipelined commands and, none can be interactive.
|
||
*
|
||
* Here are some examples of both types of inspection entries.
|
||
* The first entry will be ignored due to the initial '#' character.
|
||
* For clarity, the pseudo tab depictions (^I) are surrounded by an
|
||
* extra space but the actual tabs would not be.
|
||
*
|
||
* # pipe ^I Sockets ^I lsof -n -P -i 2>&1
|
||
* pipe ^I Open Files ^I lsof -P -p %d 2>&1
|
||
* file ^I NUMA Info ^I /proc/%d/numa_maps
|
||
* pipe ^I Log ^I tail -n100 /var/log/syslog | sort -Mr
|
||
*
|
||
* Caution: If the output contains unprintable characters they will
|
||
* be displayed in either the ^I notation or hexidecimal <FF> form.
|
||
* This applies to tab characters as well. So if one wants a more
|
||
* accurate display, any tabs should be expanded within the 'fmts'.
|
||
*
|
||
* The following example takes what could have been a 'file' entry
|
||
* but employs a 'pipe' instead so as to expand the tabs.
|
||
*
|
||
* # next would have contained '\t' ...
|
||
* # file ^I <your_name> ^I /proc/%d/status
|
||
* # but this will eliminate embedded '\t' ...
|
||
* pipe ^I <your_name> ^I cat /proc/%d/status | expand -
