You can also find files by their size and time in the Linux ubuntu system. The following commands has been given for this:

And also know as some commonly used size suffixes:

  • c: bytes
  • k: kilobytes
  • M: megabytes
  • G: gigabytes
  • b: 512-byte blocks

For example, the following command will find each file in the /usr directory that is exactly 60 bytes:

find /usr -size 60c

To find files that are less than 100 bytes, Use the following command:

find /usr -size -100c

To find files over 800 megabytes in the /usr directory, Use the following command:

find /usr -size +800M

Find File By Time using Terminal

Here we will talk about how to find time recording files in the Linux Ubuntu system.

  • Access Time: The last time a file was read or written to.
  • Modification Time: The last time the contents of the file were modified.
  • Change Time: The last time the file’s inode metadata was changed.

For example, to find files in the /usr directory that were modified in the previous day, use the following command:

find /usr -mtime 1

If you want files that were accessed less than a day ago, you could run this command:

find /usr -atime -1

To find files that last had their meta information changed more than 3 days ago, you might execute the following:

find /usr -ctime +3

These options also have companion parameters you can use to specify minutes instead of days:

find /usr -mmin -1

This will give the files that have been modified in the last minute.

find can also do comparisons against a reference file and return those that are newer:

find / -newer reference_file
