如何在
linux中使用–nice = -10 with cp命令？
以下是我尝试该选项时的示例,它给出了错误无法识别的选项
EX错误：
cp --nice=-20 -r dir1 /d/ cp: unrecognized option `--nice=-20' Try `cp --help' for more information.
解决方法
nice是一个命令,它不是cp命令的选项.
从男人好：
NAME
nice - run a program with modified scheduling priority
SYNOPSIS
nice [OPTION] [COMMAND [ARG]...]
DESCRIPTION
Run COMMAND with an adjusted niceness,which affects process scheduling.
With no COMMAND,print the current niceness. Nicenesses range from -20
(most favorable scheduling) to 19 (least favorable).
-n,--adjustment=N
add integer N to the niceness (default 10)
所以为了你的目的,你会使用这个：
nice -n -20 cp -r dir1 /d/
