How To Find File By Name In Linux

Linux detect command is a powerful tool that can be used to locate and manage files and directories based on a wide range of search criteria. This mail service will cover how to notice file by name in Linux.

The following Linux command can exist used to find file past proper noun.

discover /path -name *.txt
discover /path -type f -name exam.txt
discover /path -name failed*.* -type f
detect /path -type f -not -proper noun "*.html"
find / -proper name "file.txt" -size +4M
find /dev/ -blazon b -name "sda*"

Find control Syntax

When using detect, we would follow the syntax below.

find [options] [path] [expression]

options: This is optional. We can leave this out near of the time. We tin can read the manual page for all the options the find control has.
path: This is the directory we want to search.
expression: This is where nosotros place our search criteria for what we want to find whether past name, or size etc.

Detect File By Name in Current Directory and Subdirectory

To list all files in the electric current directory, we can use this command. ./ means current directory here.

detect ./

If nosotros need to listing the file which name is 'examination', nosotros tin can apply this command.

find ./ -name 'examination'

If there is more i file which name has 'examination' in it similar test1, test2, we can use this command.

find ./ -name '*test*'

Notice File Past Name in Multiple Directories

If we desire to search and listing all files with a given name in multiple directories, we tin either start the search at root directory, or if we know the directories, we can specify them.

Instance:

detect ./examination ./logs -name failed*.* -type f

Sample output:

./test/failed_tests.txt
./logs/failed_tests.log

Find File by Name with Wildcards

Nosotros tin use basic shell wildcard characters to augment our search. For instance, the asterisk (*) represents whatever number of characters:

$ observe ~ -iname "foo*"
/abode/tux/Documents/examples/foo
/dwelling house/tux/Documents/examples/Foo
/habitation/tux/Documents/examples/foo.xml
/home/tux/Documents/examples/foobar.txt

A question mark (?) represents a single character:

$ find ~ -iname "foo*.???"
/home/tux/Documents/examples/foo.xml
/dwelling/tux/Documents/examples/foobar.txt

This isn't regular expression syntax, so the dot (.) represents a literal dot in this example.

Find File past Name in Accented path

Absolute path is a complete path from the start of the actual filesystem from / directory.

To list all files in the file system with a specified base file name, blazon:

find /opt -name .profile -impress

This command searches the /opt directory and prints the consummate path names of all files named .profile.

The /opt (slash) instructs the find command to search the /opt directory and all of its subdirectories. In order non to waste time, information technology is best to limit the search by specifying the directories where we call back the files might be.

Observe Multiple Files by Names

Here is a little complex example. This command will remove all files named a.out or *.o that are not accessed for a week and that are not mounted past using nfs.

observe / $ -proper name a.out -o -name '*.o' $ -atime +seven ! -fstype nfs -exec rm {} \;

Note: The number that is used within the -atime expression is +seven. It is the correct entry if we want the command to act on files that are not accessed for more than a week (vii 24-hour periods).

Notice File by Name with not operator

This Linux find command using the "not" operator creates a list of all files not ending with the .html file extension (filename pattern).

find . -type f -not -name "*.html"

We can also use the following control to become this.

find . -type f ! -name "*.html"

Find File by Proper name and other options

find / -proper name "file.txt" -size +4M
find /dev/ -type b -proper noun "sda*"
find / -type d -name "a.txt"
find /opt -blazon f -name 'howtouselinux' -mtime +1
