Technical difficulty: elementary
Author: light rain and snow
Linux classic question = BASICS (zt)

0001
Modify host name
VI/etc/sysconfig/network, change the hostname line to hostname = host name, and the modification will take effect after restart

0002
RET Hat Linux is started to the text interface (XWindow is not started)
Change ID: 5: initdefault in/etc/inittab to 3

0003
Automatic upgrade and update of RedHat (huhuuworm)
Go to www.redhat.com/corp/support/errata/
Upgrade RPM except kernel: up2date-u
Upgrade RPM including kernel: up2date-u-F

0004
LINUX partition software in Windows
Paragon.ext2fs.anywhere.2.5.rarand 410e2fs-1.00-pre4.zip

0005
Mount usage (sakulagi)
FAT32 partition Mount-O codePage = 936, iocharset = cp936/dev/hda7/mnt/CDROM
NTFS partition Mount-O iocharset = cp936/dev/hda7/mnt/CDROM
ISO file Mount-o loop/ABC. ISO/mnt/CDROM
Floppy Disk Mount/dev/fd0/mnt/floppy
USB flash Mount/dev/sda1/mnt/CDROM
Mount-A for all/etc/fstab content
You can specify the file format "-T format", which can be vfat, ext2, and ext3.

0006
Use the FAT partition of the local hard disk in VMware Linux
Share the local FAT partition, and then use smbfs on Vmware. You can put the following rows in/etc/fstab:
// Win_ip/d $/mnt/d smbfs defaults, auto, username = win_name, password = win_pass, codePage = 936, iocharest = gb2312 0 0
Here, win_ip is your windows IP address;
D $ is the name of the shared D disk in your Windows system;
/Mnt/D: mount the partition to the Linux directory;
Win_name and win_pass are users who can read the partition in windows, such as your Administrator name and password.
If you run/etc/rc. d/init. d/netfs, the partition will be automatically mounted at startup.

0007.
Delete an object named-
Rm./-
Rm ---A tells RM that this is the last option. For details, see getopt.
Ls-I to list inum, and then use find.-inum inum_of_thisfile-exec RM {}\;

0007. B
Delete an object named \
Rm \

0007. c
Delete the/and '\ 0 files with names
These characters are not allowed by the normal file system, but may be generated in the file name. For example, the NFS file system in UNIX is used on the Mac system.
1. Solution: mount the NFS file system to a system that does not filter/character to delete files with special file names.
2. You can also remove other files in the directory with the wrong file name. The LS-ID displays the inum and umount file systems containing the file directory,
Clri clears the inum, fsck, mount, check your lost + found, rename the file in it.
It is best to delete any file name through Windows FTP!

0007. d
Delete an object with invisible characters
List file names and dump them to files: ls-L> aaa
Then edit the file content and add the RM command to make its content the format for deleting the above file:
VI aaa
[Rm-r *******
]
Add the execution permission chmod + x AAA to the file
Run $ aaa

0007. e
Delete an object of zero size
Rm-I 'Find./-size 0'
Find./-size 0-exec RM {}\;
Find./-size | xargs Rm-F & very effective
For file in * # define the file type to be deleted
Do
If [! -S $ {file}]
Then

Rm $ {file}
Echo "RM $ file success! "
Fi
Done

Retrieve the forgotten root password (LILO/GRUB)
Three methods:
1. When the system enters the single-user status, directly use passwd root to change
2. Install the CD boot system and run the Linux rescue status to connect the original/partition as follows:
CD/mnt
Mkdir HD
Mount-T Auto/dev/hdax (original/partition ID) HD
CD HD
Chroot ./
Passwd Root
This can be done.
3. Take the local hard disk and mount it to other Linux systems. The method is the same as the second one.
Rh8 Medium
I. Lilo
1. When lilo appears: Enter linux single

Lilo: linux single
2. Press enter to directly access the Linux Command Line
3. # vi/etc/shadow
Delete the contents of the first line, that is, the content before "root" and "Next", in the line starting with "root,
The first line is similar
Root ::......
Save
4. # restart reboot. the root password is blank.
Ii. Grub
1. When the grub screen appears, use the up and down keys to select the one you usually start Linux (do not select DoS), and then press the e key
2. Use the up and down keys again to select the one you usually start Linux (similar to kernel/boot/vmlinuz-2.4.18-14 Ro root = label =/), and then press the e key
3. Modify the command line you see and add single. The result is as follows:
Kernel/boot/vmlinuz-2.4.18-14 single Ro root = label =/
4. Press enter to return, and then press the B key to start, you can directly enter the Linux Command Line
5. # vi/etc/shadow
Delete the contents of the first line, that is, the content before "root" and "Next", in the line starting with "root,
The first line is similar
Root ::......
Save
6. # restart reboot. the root password is blank.

2. Extract the intersection of two files (only files that exist in both files are left)
3. Delete the intersection and leave other rows.
1. Cat file1 file2 | sort | uniq
