This little program shrinks files to a given size, preserving the data at the end of the file.
Truncation is performed on line boundaries, where a line is a series of bytes ending with a newline. There is no line length restriction and files may contain any binary data.
A temporary file is created in the current directory.
A newline will be added to any non-empty file that does not end with a newline. The maximum file size will not be exceeded by this addition.
By default, files are truncated to zero bytes. The -s option may be used to change the finished size. Because the program truncates only on line boundaries, the final size may be may be smaller then the specified maximum.
The size parameter may end with a k, m, or g, indicating kilobyte (1024), megabyte (1048576) or gigabyte (1073741824) lengths. Uppercase letters are also allowed. The maximum file size is 2147483647 bytes.
If the -v flag is used, then Shrink will print a status line if a
file was shrunk.
