Linux中的命令記錄可以通過history命令檢視，這個history讀取的是哪個檔案的內容呢
當前使用者的所有bash命令記錄在~目錄下的.bash_history檔案中

當前使用者的history命令內容一覽
這幾個是Oracle安裝支援包的查詢
rpm -qa grep libaio
rpm -qa grep glibc
rpm -qa grep compat-libstdc
rpm -qa grep elfutils-libelf
rpm -qa grep elfutils-libelf-devlel
rpm -qa grep libaio-devel
rpm -qa grep libcc-
rpm -qa grep libcc
rpm -qa grep libgcc
rpm -qa grep libstdc
rpm -qa grep unixODBC
rpm -qa grep unixODBC-devel
rpm -qa grep pdksh
Linux設定環境變數
這裡用echo $PATH查詢環境變數
所有使用者的環境變數存放在/etc/profile檔案中
這是/etc/profile檔案的所有內容
[[email protected] ~]# cat /etc/profile
# /etc/profile
# System wide environment and startup programs, for login setup
# Functions and aliases go in /etc/bashrc
# It's NOT a good idea to change this file unless you know what you
# are doing. It's much better to create a custom.sh shell script in
# /etc/profile.d/ to make custom changes to your environment, as this
# will prevent the need for merging in future updates.

如果以上經驗幫到您，麻煩在左下角給點個贊，謝謝！
