Non-interactive companions

Pair htop with shell commands that produce copyable output or fit scripts.

Capture a batch snapshot with top

Use top when you need non-interactive output.

↗#

bashANYtopbatchsnapshot

bash

top -b -n 1 | head -100

Useful for logs, incident notes, or remote command output you need to paste elsewhere.

List top CPU consumers with ps

Get a quick textual top list.

↗#

bashANYpscpu

bash

ps -eo pid,user,%cpu,%mem,comm --sort=-%cpu | head

Great companion when you need machine-copyable output rather than an interactive UI.

List top memory consumers with ps

Sort textual output by memory use.

↗#

bashANYpsmemory

bash

ps -eo pid,user,%cpu,%mem,comm --sort=-%mem | head

Useful for tickets and postmortems where pasteable output matters.

Read detailed status from /proc

Inspect one process beyond what htop shows.

↗#

bashANYprocstatus

bash

sed -n '1,120p' /proc/12345/status

Useful for memory figures, thread counts, and signal masks.

Inspect limits for a process

Check open-file or resource limits.

↗#

bashANYproclimits

bash

sed -n '1,120p' /proc/12345/limits

Helpful when file descriptor exhaustion or other per-process limits are suspected.

Export and correlation recipes

Correlate what you see in htop with other system tools.

Correlate a PID with journal logs

Inspect logs for a systemd service around an incident.

↗#

bashANYjournalctllogs

bash

journalctl -u myservice --since '10 minutes ago'

A common follow-up after spotting CPU or memory spikes in htop.

Inspect open files for a PID

Use shell output when you need to save or grep the results.

↗#

bashANYlsoffiles

bash

sudo lsof -p 12345 | head -50

Complements the in-app `l` shortcut with copyable output.

Inspect sockets owned by a process

Check network connections for the suspected process.

↗#

bashANYnetworksocketslsof

bash

sudo lsof -Pan -p 12345 -i

Useful when tracing network-heavy or stuck services.

List threads for one PID with ps

Inspect thread-level CPU consumers.

↗#

bashANYthreadsps

bash

ps -T -p 12345 -o pid,tid,pcpu,pmem,comm

Useful when a multithreaded process looks hot in htop and you need per-thread detail.

Use smem for proportional memory analysis

Pair htop with PSS-focused memory reporting when available.

↗#

bashANYsmemmemory

bash

smem -rtk | head

Helpful when RSS alone is not enough to reason about shared memory usage.
