You can use following syntax:
 
   
您可以使用以下语法:
 
   
ps aux | awk '{print $1}' | xargs -I % sh -c '{ echo %; sleep 1; }'
 
   
Be careful with spaces and semicolons though. After every command between brackets, semicolon is required (even after last one).
 
   
注意空格和分号。在括号之间的每个命令之后，都需要分号(甚至在最后一个命令之后)。

如果您的awk支持:
 
   
ps aux | awk '{ system("sleep 1"); print $1 }' | xargs -I {} echo {}q
 
   
or skip awk and xargs altogether
 
   
或者干脆跳过awk和xargs
 
   
ps aux | while read -r user rest;
    echo $user
    sleep 1;
done
 
  
 
 
 

}' | xargs -I {} echo {}
ps aux
