mkdir cmd
cd cmd/
cp ~/.bash_history bash_history
history > history
ls -Rla *
find . -name ".bash_history"
find . -name ".bash_history" -exec cat {} \;
find . -name ".bash_history" -exec cat {} \; > /tmp/cmd/user_history
find . -nme ".bash_history" | xargs cat
rpm -qa
检查命令有没有被修改
比如ls
which ls
rpm -V -a /usr/bin/ls
