Partial directory resolution in linux
/dev/ Device directory
/etc/ Configuration files and service startup directories
/proc/ Display kernel and process information Virtual file system
/tmp Temporary file directory
/var Change directory is generally the directory of log files
/home/home directory
/usr User program and data help files and other directories
/bin and /sbin /usr/bin /usr/sbin user commands
/etc/profile system global variable configuration cascade
/etc/hosts
/etc/fstab record files to be mounted
/etc /rc.local //The file that stores the boot self-start command
/etc/init.d //The script that stores the system or the server starts in v mode
/etc/exports //The configuration file used by the system to set the NFS network file
/ etc/xinit.d //If the server is running in xinetd mode, the script should be placed in this directory
/etc/profile.d //A directory command or file that loads the system login program exists independently
When -bash-4.2$ appears, the
reason is that the two configuration files .bashrc and .bash_profile are lost. Enter the following commands on the command line to copy these two files to the root folder
cp /etc/skel/. bashrc /root/
cp /etc/skel/.bash_profile /root/
cat /etc/redhat-release //View version
ps -ef | grep corresponding file name: view process
The general running program is placed under sbin to verify whether the installation is successful, and it is time to go to the sbin directory in the file to view
xargs is used to hand over the things displayed by find/ls to later processing
man View command set configuration file
mv is used to rename the file
touch creates a file or modifies the file timestamp
{} with echo print sequence
sed -i (insert) -n (cancel the default output) [s#content for replacement#replacement content#g]/find file content/[p print to page][d delete found file content] file path
