Which one of the following programs will only find files that are in your PATH?
- A.
Locate
- B.
Slocate
- C.
Which
- D.
Find
Correct Answer
C. WhichExplanation
The locate command looks in a pre-built database for matches, like an
index. This database is updated on a schedule, and is sometimes outdated.
B. slocate securely searches its database of filenames. It works like locate, but it also
stores file permissions and ownership information so users cannot see files to which they
don't have access. In some distributions, locate is actually a symbolic link to slocate."
C. The which command parses every directory in the PATH environment variable,
returning the first match found. This is useful if you want to know which file gets
executed when you type a command, or if you need to know the full path of a file for
some reason. For example, security could be compromised by someone that puts an often
used executable in a directory that gets looked at earlier in your PATH statement. Thus,
every time you think you're executing a program, you're actually executing a possibly
malicious program. There is an option to make the which command return every found
result, but it will remain restricted to the PATH.
D. Finally, the find command just does a complete search. It accepts the starting directory
as an argument, and just looks at every file and directory it finds. It takes a long time, but
it's guaranteed to find anything that the user has read permission to.Rate this question:

Which program finds only files that are in your path?
Correct Answer

its database to make searching faster, but it will also store file permissions and
ownership so that users will not see files they do not have access to.Rate this question:
