Find files by data and type in Linux

 How do I find files in a Linux system? or specifically on Centos Linus?

The command ls will list files in a specific directory. Using the asterisk (*) its possible to display list of files and directory with wildcards. 

E.g.

ls -l

ls -lt

ls -lrt

ls /etc

ls /etc/h*

Search files with command grep and ls

ls -lt /etc/ | grep filename

Search files with command find

find directory -type f -name filename

The command find provide more flexibility in search for files.

Search ordinary files that has the extension .cpp

find /home/you -iname "*.cpp" -type f

Search ordinary files that has the extension .cpp that are more than 30 days

find /home/you -iname "*.cpp" -atime -30 -type f

Search files from a given modified date

find . -type f -newermt 2023-01-01

Search files from a given access date

find . -type f -newerat 2017-09-25 ! -newerat 2017-09-26

Search files given a date range

touch --date "2007-01-01" /tmp/start.file

touch --date "2008-01-01" /tmp/end.file

find /data/images -type f -newer /tmp/start.file -not -newer /tmp/end.file
