The Find command is one of the most powerful commands

The Find command is one of the most powerful commands, but it is also one of the most difficult commands for command-line structures to master.
# Find/-print | WC-L displays the number of files and directories in the system.
# Find/-user $LOGNAME-print displays all files and directories for that user in the system.
# Find/-size 100-print display file size is blocks.
# Find/-size-100-print shows file size less than blocks.
# Find/-size +100-print shows file size greater than blocks.
# Find/-name core-exec rm {} \; Find and delete the core file.
# Find. -exec chown $LOGNAME {} \; Modifies all files in a directory to which the user belongs.
# find.-type d-exec chmod 770 {} \; Modify permissions for all directories under a directory.


Find: (The following are all operating under Hp-unix)
Find./dir-mtime +10-exec rm-rf {}\; Locate the file 10 days ago in the Dir directory, and then delete it. The E x E C option is followed by the command to be executed, followed by a pair of {}, a space and a \, and finally a semicolon.
Find./dir-mtime +20 | Xargs rm found 20 days ago and deleted files in the Dir directory. Xargs efficiency and performance are better than direct with-EXEC option
Find/dir-mtime-2 in dir directory for files within two days
Find./dir-mtime +3 files found three days ago in the Dir directory
Find/dir-user fly in the Dir directory for files belonging to fly users
Find./dir-group user finds files belonging to the user group in the dir directory
Find./dir-type d looking for files of file type directory in dir directory
Find./dir-name "*.sh"-depth when using the f i n d command, you might want to match all of the files before looking in subdirectories. Use the D e p t h option to make the f i n d command do this
