First, mkdir new directory
1. Go to the TMP directory and look at the subdirectories below the directory
[Email protected] ~]# cd/tmp
[[email protected] tmp]# ls
Hsperfdata_root Ks-script-3cwmoc SYSTEMD-PRIVATE-810F661CB5D247129113C096F86D7DB2-CUPS.SERVICE-FEKFSX Vitest Yum.log
2. mkdir create the test directory and view
[Email protected] tmp]# mkdir test
[[email protected] tmp]# ls
Hsperfdata_root Ks-script-3cwmoc SYSTEMD-PRIVATE-810F661CB5D247129113C096F86D7DB2-CUPS.SERVICE-FEKFSX Test vitest Yum.log
3. Create catalogs in batches
[Email protected] tmp]# mkdir-p test1/test2/test3/test4
[[email protected] tmp]# ls
hsperfdata_root Ks-script-3cwmoc SYSTEMD-PRIVATE-810F661CB5D247129113C096F86D7DB2-CUPS.SERVICE-FEKFSX test test1 vitest yum.log
[[email Protected] tmp]# CD test1
[[email protected] test1]# ls
test2
[[email protected] test1]# CD test2
[[email protected] test2]# ls
test3
[[email protected] test2]# cd test3
[[email Protected] test3]# ls
test4
4, new directory with permissions of Rwx--x--x
[Email protected] tmp]# mkdir-m 711 Test2
[Email protected] tmp]# ls-l
Total 4
Drwxr-xr-x. 2 root root (DEC) 01:18 Hsperfdata_root
-RWX------. 1 root root 827 Dec 01:26 Ks-script-3cwmoc
DRWX------. 3 root root Dec 20:52 systemd-private-810f661cb5d247129113c096f86d7db2-cups.service-fekfsx
Drwxr-xr-x. 2 root root 6 Dec 03:36 test
Drwxr-xr-x. 3 root root 03:38 test1 permissions for the original directory
Drwx--x--x. 2 root root 6 Dec 03:40 test2 new directory Permissions
Drwxr-xr-x. 2 root root (DEC) 02:18 vitest
-RW-------. 1 root root 0 Dec 01:06 yum.log
Second, rmdir delete directory
1. Delete Catalog test
[Email protected] tmp]# rmdir test
2. View the results of the deletion
[Email protected] tmp]# ls-l
Total 4
Drwxr-xr-x. 2 root root (DEC) 01:18 Hsperfdata_root
-RWX------. 1 root root 827 Dec 01:26 Ks-script-3cwmoc
DRWX------. 3 root root Dec 20:52 systemd-private-810f661cb5d247129113c096f86d7db2-cups.service-fekfsx
Drwxr-xr-x. 3 root root 03:38 test1
Drwx--x--x. 2 root root 6 Dec 03:40 test2
Drwxr-xr-x. 2 root root (DEC) 02:18 vitest
-RW-------. 1 root root 0 Dec 01:06 yum.log
3. Delete the other directories below the test directory in bulk
[Email protected] tmp]# rmdir-p test1/test2/test3/test4
[Email protected] tmp]# ls-l
Total 4
Drwxr-xr-x. 2 root root (DEC) 01:18 Hsperfdata_root
-RWX------. 1 root root 827 Dec 01:26 Ks-script-3cwmoc
DRWX------. 3 root root Dec 20:52 systemd-private-810f661cb5d247129113c096f86d7db2-cups.service-fekfsx
Drwx--x--x. 2 root root 6 Dec 03:40 test2
Drwxr-xr-x. 2 root root (DEC) 02:18 vitest
-RW-------. 1 root root 0 Dec 01:06 yum.log
Ii. usage of CP
1. Copy the Install.log to the TMP directory.
[email protected] tmp]# CP ~/install.log/tmp/install.log
[[email protected] tmp]# ls
Hsperfdata_root Install.log Ks-script-3cwmoc SYSTEMD-PRIVATE-810F661CB5D247129113C096F86D7DB2-CUPS.SERVICE-FEKFSX Test2 vitest Yum.log
2, if the directory already exists, then +I coverage CP
[Email protected] tmp]# cp-i ~/install.log/tmp/install.log
Cp:overwrite '/tmp/install.log '? Y
3. RM Delete Directory
[Email protected] tmp]# RM install.log
Rm:remove regular empty file ' Install.log '? Y
[[email protected] tmp]# ls
Hsperfdata_root Ks-script-3cwmoc systemd-private-810f661cb5d247129113c096f86d7db2-cups.service-fekfsx test2 vitest Yum.log
4. Rm+i Avoid deleting errors
[Email protected] tmp]# rm-i Install.log
Rm:remove regular empty file ' Install.log '? Y
5. Forcibly Delete Empty directory
[Email protected] tmp]# RM etc
Rm:cannot Remove ' etc ': is a directory
[Email protected] tmp]# Rm-r etc
Rm:remove directory ' etc '? Y
Three, MV usage
1. Create the Install folder and move the Install.log file to the directory below
[Email protected] ~]# cd/tmp
[email protected] tmp]# CP ~/install.log Install.log
[[email protected] tmp]# mkdir Install
[[Email protected] tmp]# mv Install.log Install
[Email protected] tmp]# Cd/tmp/install
[[email protected] install]# ls
Install.log
Four, cat file lookup usage
[Email protected] ~]# cat/etc/issue
\s
Kernel \ r on an \m
Five, Touch usage
1. Create 1 files and view this file
[email protected] tmp]# Touch Testtouch
[Email protected] tmp]# Ls-al Testtouch
-rw-r--r--. 1 root root 0 Dec 04:02 Testtouch
Mkdir,rmdir,cp,rm,mv,cat,touch usage
