Linux 설정 파일 이해하기 [Bottom] [Top]

Linux 나 Unix 를 사용하다보면 설정 파일이 너무 많아 제대로 알지도 못하고 사용하는 경우가 많다. 특히 서버를 관리 하면서도 제대로 알지도 못하고 허술하게 관리하는 경우가 비일비재 하다.

그래서 이런 설정 파일들을 분류하고 사용법에 대하여 아래 주소의 웹문서를 참고한다.

Linux 시스템을 관리, 운영하기 위해 몇개의 명령어를 사용하고 있을까? 대체로 많은 사람들이 잘 모르고 있을 것이라고 생각한다. 아마도 주로 사용하는 몇개만 알고 있을것이다.

그래서 Linux 시스템 관리용 명령어들을 모아서 정리해 보았다.

Description

The procps package contains a set of system utilities that provide system information. Procps includes ps, free, skill, snice, tload, top, uptime, vmstat, w, and watch. The ps command displays a snapshot of running processes. The top command provides a repetitive update of the statuses of running processes. The free command displays the amounts of free and used memory on your system. The skill command sends a terminate command (or another specified signal) to a specified set of processes. The snice command is used to change the scheduling priority of specified processes. The tload command prints a graph of the current system load average to a specified tty. The uptime command displays the current time, how long the system has been running, how many users are logged on, and system load averages for the past one, five, and fifteen minutes. The w command displays a list of the users who are currently logged on and what they are running. The watch program watches a running program. The vmstat command displays virtual memory statistics about processes, memory, paging, block I/O, traps, and CPU activity.

The psmisc package contains utilities for managing processes on your system: pstree, killall, and fuser. The pstree command displays a tree structure of all of the running processes on your system. The killall command sends a specified signal (SIGTERM if nothing is specified) to processes identified by name. The fuser command identifies the PIDs of processes that are using specified files or filesystems.
