尽量使用 -0 或 -print0选项以便用 NULL 来分隔文件名,例如 locate -0 pattern | xargs -0 ls -al 或 find / -print0 -type d | xargs -0 ls -al。如果 for 循环中循环访问的文件名含有空字符(空格、tab 等字符),只需用 IFS...
Bash 变量要用引号括起来,比如"$FOO"。尽量使用-0或-print0选项以便用 NULL 来分隔文件名,例如locate -0 pattern | xargs -0 ls -al或find / -print0 -type d | xargs -0 ls -al。如果 for 循环中循环访问的文件名含有空字符(空格、tab 等字符),只需用IFS=$'\n'把内部字段分隔符设为换行符。
