查看磁盘使用情况

du -h /home/rambo/ --max-depth=1 | sort -hr | head -n 10

查看显卡使用情况

常用的方法

nvidia-smi
ps -aux | grep $pid

一条命令解决

# 先安装nvidia-htop库
# pip3 install nvidia-htop
nvidia-htop.py -l

vim ~/.bashrc
# 最后一行添加
alias gpu='nvidia-htop.py -l'
source ~/.bashrc

记录一次java -version不起作用的问题

# 系统默认装了一个java在/etc/profile
export JAVA_8_HOME=/usr/local/java/jdk1.8.0_351
export JAVA_11_HOME=/usr/local/java/jdk-11.0.17
export JAVA_17_HOME=/usr/local/java/jdk-17.0.5

export JAVA_HOME=$JAVA_8_HOME

export CLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME/lib:$CLASSPATH
export PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATH
export JRE_HOME=$JAVA_HOME/jre

# 我自己装的java导入是在~/.bashrc
JAVA_HOME=/home/rambo/java/jdk-17.0.11/
CLASSPATH=%JAVA_HOME%/lib:%CLASSPATH
export PATH CLASSPATH JAVA_HOME

发现不论怎么改.bashrc都不起作用，最后用echo $PATH，发现1.8在17.0之前，这说明PATH导入有问题
/home/rambo/miniconda3/bin:/home/rambo/miniconda3/condabin:/usr/local/java/jdk1.8.0_351/bin:/bin:/usr/local/cuda/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/home/rambo/java/jdk-17.0.11/bin:/home/rambo/java/jdk-17.0.11/jre/bin:/home/rambo/java/jdk-17.0.11/bin:/home/rambo/miniconda3/bin:/home/rambo/miniconda3/condabin:/usr/local/java/jdk1.8.0_351/bin:/bin:/usr/local/cuda/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/home/rambo/java/jdk-17.0.11/bin:/home/rambo/java/jdk-17.0.11/jre/bin:/home/rambo/java/jdk-17.0.11/bin:/home/rambo/java/jdk-17.0.11/bin

将.bashrc改成以下就OK了
export JAVA_HOME=/home/rambo/java/jdk-17.0.11
export CLASSPATH=$JAVA_HOME/lib/:$CLASSPATH
export PATH=$JAVA_HOME/bin:$PATH
