Linux command to truncate size of large files
| truncate -s {size_MB_GB} {file_and_path} | Truncate command to either shrink or expand the size of a file |
Replace with the desired size in bytes, kilobytes (K), megabytes (M), gigabytes (G), or terabytes (T), and with the name of the file you want to truncate.
Example:
truncate -s 800MB /var/log/user.log
Note that this command will permanently delete any data in the file that is beyond the specified size. So, make sure to back up any important data before truncating a file.
