How can I find a specific file from a Linux terminal?

Question

I am trying to find where index.html is located on my linux server, and was wondering if there was a command to do that. Very new to linux and appreciate any he

Answer 1

Find from root path find / -name "index.html"

Find from current path find . -name "index.html"

Answer 2

find /the_path_you_want_to_find -name index.html

Answer 3

Try this (via a shell):

update db
locate index.html

Or:

find /var -iname "index.html"

Replace /var with your best guess as to the directory it is in but avoid starting from /

Answer 4

In general, the best way to find any file in any arbitrary location is to start a terminal window and type in the classic Unix command "find":

find / -name index.html -print

Since the file you're looking for is the root file in the root directory of your web server, it's probably easier to find your web server's document root. For example, look under:

/var/www/*

Or type:

find /var/www -name index.html -print

Answer 5

The below line of code would do it for you.

find / -name index.html

However, on most Linux servers, your files will be located in /var/www or in your user directory folder /home/(user) depending on how you have it set up. If you're using a control panel, most likely it'll be under your user folder.

Answer 6

Solution: Use unix command find

The find utility recursively descends the directory tree for each path listed, evaluating an expression (composed of the 'primaries' and 'operands') in terms of each file in the tree.

• You can make the find action be more efficient and smart by controlling it with regular expressions queries, file types, size thresholds, depths dimensions in subtree, groups, ownership, timestamps , modification/creation date and more.
• In addition you can use operators and combine find requests such as or/not/and etc...

The Traditional Formula would be :

find <path> -flag <valueOfFlag>

Easy Examples

1.Find by Name - Find all package.json from my current location subtree hierarchy.

find . -name "package.json"

2.Find by Name and Type - find all node_modules directories from ALL file system (starting from root hierarchy )

sudo find / -name "node_modules" -type d

Complex Examples:

More Useful examples which can demonstrate the power of flag options and operators:

3.Regex and File Type - Find all javascript controllers variation names (using regex) javascript Files only in my app location.

find /user/dev/app -name "*contoller-*\.js" -type f

-type f means file -name related to regular expression to any variation of controller string and dash with .js at the end

4.Depth - Find all routes patterns directories in app directory no more than 3 dimensions ( app/../../.. only and no more deeper)

find app -name "*route*" -type d  -maxdepth 3

-type d means directory -name related to regular expression to any variation of route string -maxdepth making the finder focusing on 3 subtree depth and no more <yourSearchlocation>/depth1/depth2/depth3)

5.File Size , Ownership and OR Operator - Find all files with names 'sample' or 'test' under ownership of root user that greater than 1 Mega and less than 5 Mega.

find . \( -name "test" -or -name "sample" \)  -user root -size +1M -size -5M

-size threshold representing the range between more than (+) and less than (-) -user representing the file owner -or operator filters query for both regex matches

6.Empty Files - find all empty directories in file system

find / -type d -empty

7.Time Access, Modification and creation of files - find all files that were created/modified/access in directory in 10 days

# creation (c)
find /test -name "*.groovy" -ctime -10d
# modification (m)
find /test -name "*.java" -mtime -10d
# access (a)
find /test -name "*.js" -atime -10d

8.Modification Size Filter - find all files that were modified exactly between a week ago to 3 weeks ago and less than 500kb and present their sizes as a list

find /test -name "*.java" -mtime -3w -mtime +1w -size -500k | xargs du -h
