You can use the 'find' command in combination with the '-size' option to locate and remove files based on their size. For example, to find and list files larger than a specific size (say, 10MB) use the following command syntax:

find /path/to/your/directory -type f -size +10M

Here,

• replace '/path/to/your/directory' with your directory location.
• -type f, ensures that you are looking for regular files (not directories or other types)
• -size +10M, specifies that you want files larger than 10MB.

Once you identify the files you want to remove, you can use the '-exec' option to pass them to the 'rm' command to delete them:

find /path/to/your/directory -type f -size +10M -exec rm {} \;

Here,

• '{}', represents the current file that 'find' has matched.
• '\;', denotes the end of the '-exec' command.
  NOTE: Be careful when using the 'rm' command, especially with 'find'. As the data will be permanently deleted.
