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/
