cssplit - Split a CScout processing script into smaller scripts
cssplit [-h] -s N file [file ...]
The cssplit command-line program splits a CScout processing script into N smaller scripts for parallel or distributed processing. Each output script is named using a zero-padded sequence, starting with file-0000.cs.
The input is read from the specified file(s), and the output files are written into the current working directory.
This tool is useful for distributing the workload of a large CScout analysis across multiple scripts for efficiency or manageability.
-s, --shards N
Specifies the number of output scripts to generate. The input processing script is divided into N approximately equal parts. Each output script contains the appropriate subset of the input commands to ensure no loss of information during the split. Compilation units from multiple inter-dependent projects (e.g. different configurations of the same executable) are distributed to the scripts so as to maximize locality of reference.
-h, --help
Display a brief usage message and exit.
To split an input processing script into 4 smaller scripts:
cssplit -s 4 make.cs
This will create the following files in the current directory:
file-0000.cs file-0001.cs file-0002.cs file-0003.cs
Each file contains a portion of the original processing script.
cscout(1), cscut(1), csmake(1)
