5) Find File Find
Finding Files That Match A Pattern
$
Find. -name 'd *'
THE DOT (.) Find to search the current directory and itssubdirector. The -name Option File Name OPTION File Name
Pattern (in this case d *) TELLS FIND TO Search for All File Names That Match
That Pattern. in this Example, Find Will Look for All File Names Beginning
WITH D. Note That D * is enclosed by Single Quotes 'D *'.
$ FIND / HOME / LESLIE -NEWER MyFile
This Example Can Be Read As Follows: in Directory / Home / Leslie and ITS
Subdirectories, Find All Files Modified After Myfile. (To Determine WHEN A
File Was Last Modified, Use The Ll Command.)
$ FIND. -NAME '* .TMP' - EXEC RM {} /;
You Can Execute Commands on Files Located with the Find Command. Let's say you want to remove all Files with a extension in Thecurrent Directory and ITS Subdirectories.
To Find Files That Do Not Match A Specific Pattern, Use the logical not
Operator, The Exclamation Mark (!). after useing this operator, you must
Use Options to Define File Attributes Such As File Name. Then, Files Are
Found That Do Not Have The attributes you specify.
For Example, To Find All Files In / Tmp That Aren't OWNED BY LESLIE, USE
This Command:
$ FIND / TMP / (! -user leslie /)
THE / Escapes the Parentheses So That They Are Not Interpreted As Special
Characters by the shell. To find files That Have Two DistINCT Attributes, Use the logical and
Operator, Expression -a Expression. For Example, To Find All Directories IN /
That Are Owned by leslie, use this command:
$ FIND / / (-type d -a -user leslie /)
To Find Files That Have Either OR Both of Two Attributes, Use The Logical OR
Operator, Expression -o Expression. For Example, To Remove All Files Ending
With .o or named a.out what has not been accessed for a week, uschacomb:
$ FIND / / (-Name a.out -o -name '* .o' /) -time 7 -exec rm {} /; 6) Directory Abbreviation CD =========== ~ Users login's Working Directory ~ username Specifies a USER's Working Directory.

Current Directory (Parent of Working Directory) Change the working directory location ================ Perform format CD [Name] Name can be used for directory name path or directory abbreviation Example: CD change the directory location to the user login Working Directory (Start Directory) CD DIR1 Change Directory Location to DIR1 Directory Location CD ~ USER Change the directory location to the user's Working Directory CD .. Change the directory location to the upper layer of the current directory (ie Parent of Working Directory Cd ../user changes the directory location to the directory location of the relative path user under the directory location of the user, change the directory location to the directory location of the absolute path (Full Path)
