# 사용 예 1
echo 1 2 3 4 | xargs echo
# 이 코드는 1 2 3 4 argument를 xargs 를 이용해서 다시 echo에게 전달하는 명령어

find ./ -name ".bak" | xargs -0 -I file rm file
# -0은 file 이름에 space가 들어가있을 때 이를 take cares 해줌
#    (아래 섹션 참조 Dealing file names with blank spaces and newline)
# -I file 은 find에서 넘어온 결과들을 "file" 이라는 변수로 치환.

자주 찾게 되는 패턴!

ls -p | grep -v / | xargs -I file cat file

Dealing file names with blank spaces and newline

The following will work incorrectly if there are any filenames containing newlines or spaces (it will find out all .mp3 file located in current directory and play them using mplayer):

$ find . -iname "*.mp3" -print | xargs mplayer

To get rid of this problem use -0 option:

$ find . -iname "*.mp3" -print0 | xargs -0 -I mp3file mplayer mp3file

To find out all *.c file located in 100s of subdirectories and move them to another directory called ~/old.src, use:

$ find /path/to/dir -iname "*.c" -print0 | xargs -0 -I file mv file ~/old.src
