devCiTi. | linux commands:find

Use the find command to recursively find files and folders matching a particular search pattern.

For example,find all files under the current tree that have the .js extension and print the relative path of each file:

~$ find . -name '*.js'

The special character * tells the terminal to print relative path of each file.The quotes tells the shell to avoid interpreting special characters

Find directories under the current tree matching the name "src":

~$ find . -type d -name src

Use -type f to search only files or -type l to only search symbolic links.

-name is case sensitive ,use -iname to perform a case-insesitive search.

You can search under multiple root trees:

~$ find folder1 folder2 -name filename.txt

Find directories under the current tree matching the name “node_modules” or “public”:

~$ find . -type d -name node_modules -or -name public

Also exclude a path,using -not -path:

~$ find . type d -name '*.md' -not -path 'node_modules'

Search files that have more than 100 characters(bytes) in them:

~$ find . -type f -size +100c

Search files bigger than 100KB but smaller than 1MB:

~$ find . type f -size +100k -size -1M

Search files edited more than 3 days ago:

~$ find . -type f -mtime +3

Search files edited in the last 24 hours:

~$ find . -type f -mtime -1

You can also delete all the files matching a search by adding the -delete option.This deletes all the files edited in the last 24 hours:

~$ find . -type f -mtime -1 -delete

You can execute a command on each result of the search.

For example run cat to print the file content:

~$ find . -type f -exec cat {} \;
