truncate: Extend the file size by 50 MiB, fill with holes (which reads as zero bytes).
$ truncate --size +${50M} ${filename}
try on your machine
The command "truncate --size +${50M} ${filename}" is used to truncate or resize a file to a specified size.
Here is a breakdown of the command:
- "truncate" is the command itself, which is used to manipulate files.
- "--size" is an option for the truncate command, indicating that you want to specify the new size for the file.
- "+${50M}" is the size argument, where "+50M" means you want to increase the file size by 50 megabytes.
- "${filename}" is the placeholder for the actual filename or path of the file you want to resize.
To further clarify, let's take an example: if the command is executed as "truncate --size +50M myfile.txt", it will increase the size of the "myfile.txt" file by 50 megabytes.
