Command line

command	Explanation
`cd -`	go back
`mkdir -p './oneleve/{a,b,c}/{c,d}'`	Create folder hierarchy
`rm -rf dirname`	Remove dir with contents
`find . -name testfile.txt`	Find a file called testfile.txt in current and sub-directories.
`find /home -name *.jpg`	Find all .jpg files in the /home and sub-directories.
`find . -type f -empty`	Find an empty file within the current directory.
`find /home -user exampleuser -mtime -7 -iname ".db"`	Find all .db files (ignoring text case) modified in the last 7 days by a user named exampleuser.
`find . -name "*.bak" -delete`	Careful!! To delete the files that end up matching your search, you can add -delete at the end of the expression. Do this only when you are positive the results will only match the files you wish to delete.
`find . -type f -exec grep "example" '{}' \; -print`	This searches every object in the current directory hierarchy (.) that is a file (-type f) and then runs the command grep “example” for every file that satisfies the conditions. The files that match are printed on the screen (-print). The curly braces ({}) are a placeholder for the find match results. The {} are enclosed in single quotes (’) to avoid handing grep a malformed file name. The -exec command is terminated with a semicolon (;), which should be escaped (;) to avoid interpretation by the shell.
