xargs 命令详解

xargs  是一条Unix和类Unix操作系统的常用命令。它的作用是将参数列表转换成小块分段传递给其他命令，以避免参数列表过长的问题。

EXAMPLES 

 

find /tmp -name core -type f -print | xargs /bin/rm -f 

Find files named core in or below the directory /tmp and delete them. Note that this will work incorrectly if there are any filenames con- taining newlines or spaces. 

find /tmp -name core -type f -print0 | xargs -0 /bin/rm -f 

Find files named core in or below the directory /tmp and delete them, processing filenames in such a way that file or directory names con- taining spaces or newlines are correctly handled. 

cut -d: -f1 < /etc/passwd | sort | xargs echo 

Generates a compact listing of all the users on the system
