Question

" a.     Let’s start with something easy, we will find all files that end with .txt in your home directory (~). Issue the command find ~ -name “*.txt”. Recall that ~ (tilde) represents your home directory. Use the find command to locate all .txt files in the entire file system (starting at /). 21.) What command did you enter? 22.) You will receive some errors, why? The command find /sys –name core* will locate any files in /sys starting with the characters “core”. Use the command. 23.) How many are found? Now issue a find command to locate any file in /usr/sbin with the word “user” in its title (anywhere in the title). 24.) What command did you use? 25.) How many files did you find? "

Explanation / Answer

I tried these commands in my Centos 7 PC. Results of this questions may vary from one computer to another.

find command to locate all .txt files in the entire file system (starting at /) :

root@centospc# find / -name "*.txt" | wc -c

(I didn't receive any error, there were 21249 files found with the above command)

(I used "wc -c" to count the results found)

-------------------------------------------------------------------------------------------------

Used the command :  find /sys –name core*

root@centospc# find /sys -name core* | wc -c

4902

so 4902 files are found using the command :  find /sys –name core*

--------------------------------------------------------------------------------------------------------------

Now issue a find command to locate any file in /usr/sbin with the word “user” in its title:

tried 3 ways to find results

root@centospc# find /usr/sbin -name "user*" | wc -c

96 (means 96 files are found with this combination : "user*" )

root@centospc# find /usr/sbin -name "*user*" | wc -c

271 (means 271 files are found with this combination : "*user*" )

root@centospc# find /usr/sbin -name "*user" | wc -c

52 (means 52 files are found with this combination : "*user")

note : I logged in into my Centos 7 PC as root user, results may differ if you are logged in as another user.
