Finding of Directory/Path in Linux

Hi everyone❗️

I have prepared this short article, which is like a cheat sheet, for those who are just starting out in the field of cyber security and who want to improve themselves.👩🏻‍💻📝 Pathfinding commands in Linux; penetration tests, CTF solutions or OSCP etc. it is very important for us pentesters when preparing for certification exams.🎃 I hope you find it useful.🌟😌

locate

• The related command searches from a constantly updated database.
• The “locate” command searches on the database file “/var/cache/locate/locatedb”.
• That’s why we should always update the database before using it.
• The command we should use to update the database is the “updatedb” command.
• The “locate” command searches on the custom database in all possible locations.

which

• The related command indicates in which directory the executable file belonging to a command or program is located.
• It searches for directories defined in the $PATH environment variable for this operation and returns the full path if it finds a match.

find

• It performs file and directory searches on the specified criteria.
• It does this recursively.

Syntax:

find <directory> <parameter> <searched file/statement>

• Some parameters that can be used with the related command and their explanations are as follows.

Parameter:        Description:

name              name of searched file
iname             name of the searched file - case insensitive
type              Type of searched file 
                  
                  f : regular file
                  d : directory
                  b : block file
                  c : character file
                  l : symbolic link
cnewer            files modified after the given date
amin              files accessed n minutes ago
cmin              file status changed n minutes ago
atime             files accessed "n*24 hours" ago
mtime             files processed in n days
ctime             files modified in n days

• Case insensitive search for all files with filename “asd.txt” in the /root directory:

• Searching for all files with “777” permission under the /sbin directory:

• Finding and deleting “asd.txt” files under /root directory:

• { } : The found files and directories will be placed between these brackets as parameters and the program specified immediately after exec will be run accordingly.

Happy hunting❗️🥂
