Find files in Linux

[Theadmin77]

I m kind of stuck ...i need to find files with a specific criteria but i can not make it work ....

These are the ones :

1.How do you Find files under /root that contain the whole words (i.e., not part of another word) 'foo', 'bar', 'baz', 'cat', 'cut', 'cot.' using a single command ?

I tried :find /root -name 'foo.*' -name 'baz.*'-name 'cat.*'-name 'cut.*'-name 'cot.*'
but seems that is not right

2.Find files under /var that contain the character list 'xxx' or 'xxxx' or 'xxxxx'. Using \{\} and adding two lines of context before AND after each keyword found. ..

my answer: find /var -name 'xxx' ,'xxxx, 'xxxxx'

At this point i am lost ....

Any help will be very much appreciated

For number 1, do you mean that have filenames containing those words, or the files themselves containing those words?
The tools you want in the latter case are grep and sed, not find.
Actually, I think both questions are looking for answers involving sed.

A little more on sed.
Required reading for sed (i.e. Regular Expressions).

No , i s not grep because we are looking for file names no strings within a file .
I know FIND must be used but i dont remember the correct parameters ..

In the future, you can use the command line utility man to find syntax for linux commands:

% man find
 

Here is a web version of the man page.

find /root -name 'foo' -print is the command to find files
