Detailed information on a single process in a greppable format

Utilities such as ps and top are good for looking at many processes side-by-side. However, they are inconvenient for examining many fields of a single process and are not amenable to using grep. For example: $ ps -o pid,ppid,tname,bsdstart,start_time,start,bsdtime,etime,etimes,c=LIFE%,%cpu,cputime,rss,%mem,stat,class,nice=NICE,thcount,args -p $(pgrep syncthing) PID PPID TTY START START STARTED TIME ELAPSED ELAPSED LIFE% %CPU TIME RSS %MEM STAT CLS NICE THCNT COMMAND 20149 1836 ? 19:24 19:24 19:24:58 0:24 01:54:12 6852 0 0.3 00:00:24 38428 0.2 Ssl IDL - 13 /usr/bin/syncthing -no-browser -no-restart -logflags=0 There is /proc/$PID/status: $ cat /proc/$(pgrep syncthing)/status | head Name: syncthing Umask: 0022 State: S (sleeping) Tgid: 20149 Ngid: 0 Pid: 20149 PPid: 1836 TracerPid: 0 Uid: 1000 1000 1000 1000 Gid: 1000 1000 1000 1000 but this lacks useful fields such as: - CPU usage percentage - CPU time - Resident memory size / resident set size - Memory percentage - Out of Memory Score - Elapsed time - Nice priority - I/O priority The output I desire might look something like this: Name: syncthing Process ID: 20149 Parent process ID: 1836 Full command: /usr/bin/syncthing User: exampleuser UID: 1000 State: Sleeping (S) CPU priority: 19 (low) I/O scheduling class: 2 (best-effort) I/O priority level: 7 (low) Start date (ISO): 2020-06-15T21:21:53-04:00 Start date (UTC): Tue Jun 16 01:21:53 UTC 2020 Process age: 01:54:12 Cumulative CPU time: 00:00:24 Cumulative user CPU time: 00:00:24 Cumulative system CPU time: 00:00:24 Out of memory score: 2 Out of memory adjustment factor: 0 Number of threads: 13 Number of child processes: 0 with more fields from e.g. /proc/$PID/stat and /proc/$PID/statm. Does such a utility exist? Note: this question differs from [Detailed Per-Process Profiling](https://unix.stackexchange.com/questions/43936/detailed-per-process-profiling) because I am not looking for performance profiling or monitoring over time, but rather a snapshot of process information for the specific fields mentioned above in a particular format.
