Default Action of the Split Command

B

The split command in Linux is used to split a large file into smaller files. It is commonly used when transferring large files over a network or for archival purposes. When you run the split command, you must specify the input file to split and the output file name prefix. By default, the split command uses a 1,000 line size for each output file.

Therefore, the answer to the question is B. The default action of the split command on an input file is to break the file into new files of 1,000 line pieces each.

However, it's important to note that you can specify different sizes for the output files using the -b or -l options. The -b option is used to specify the size of each output file in bytes, while the -l option is used to specify the number of lines in each output file.

For example, to split a file into 1,024 kilobyte pieces, you can use the following command:

bashCopy code
split -b 1024k inputfile outputfileprefix 

Or, to split a file into pieces that are no more than 5% of the size of the original file, you can use the following command:

bashCopy code
split -C 5% inputfile outputfileprefix 

So, while the default action of the split command is to split the file into 1,000 line pieces, you can easily customize the size of the output files using the available options.
