[Shell] PS 커맨드 화면에서 짤릴 때

스뎅(thDeng) on July 22, 2022

ps 커맨드 결과가 너무 길어서 화면을 벗어나 짤릴 때가 있다. (아래 커맨드는 docker로 kafka 컨테이너를 하나 띄웠는데, 길고 긴 classpath와 옵션으로 짤린 내용이다)

$ ps -ef
PID   USER     TIME  COMMAND
    1 root      0:18 /usr/lib/jvm/zulu8-ca/bin/java -Xmx1G -Xms1G -server -XX:+UseG1GC -XX:MaxGCPau
  511 root      0:00 ps -ef

쉽게 해결하는 방법은 echo와 함께 사용하기

$ echo "$(ps -ef)"
$ echo `ps -ef`
$ echo "$(ps aux)"

결과는 이렇게.. 아아아 길다아아아아!!

$ echo "$(ps -ef)"
