Streamline 1.8.0.1 (Default branch)

Streamline is a pipelined I/O subsystem for both kernel and application processing on Linux, with 40+ filters for pattern matching, stream reassembly, compression, etc. It exports the pipes, sockets, and pcap interfaces and uses shared memory to reduce I/O copy and context switch cost. Logical uses are rapid application development of intrusion detection systems and similar complex network processing tasks. License: GNU Lesser General Public License (LGPL) Changes:
This version updates the stream language to be a superset of Unix shell pipelines and improves support for hybrid pipelines consisting of streamline filters (e.g., in the network stack) and full Unix processes. Because of the extensive interface changes, this version is less mature than 1.7.4.5 and has little documentation (other than the mailing list). Image

2. Shell Programming and Scripting

Help me streamline this counting part of my script.

Ok, so this is a small part of a script I wrote to build disk groups using VXVM. The only problem is that I am limited to a count of 8 maximum. If I want more, I will have to add more lines of "if" statements. How can I accomplish the same thing, in a few lines, but not be limited in the max... (13 Replies)

NAME
Jocamlcp - The JoCaml profiling compiler SYNOPSIS
jocamlcp [ jocamlcp options ] [ -p flags ] filename ... DESCRIPTION
The jocamlcp command is a front-end to jocamlc(1) that instruments the source code, adding code to record how many times functions are called, branches of conditionals are taken, ... Execution of instrumented code produces an execution profile in the file ocamlprof.dump, which can be read using jocamlprof(1). jocamlcp accepts the same arguments and options as jocamlc(1). OPTIONS
In addition to the jocamlc(1) options, jocamlcp accepts the following option controlling the amount of profiling information: -p letters The letters indicate which parts of the program should be profiled: a all options f function calls : a count point is set at the beginning of each function body i if ... then ... else: count points are set in both then and else branches l 0 loops: a count point is set at the beginning of the loop body m match branches: a count point is set at the beginning of the body of each branch of a pattern-matching t try ... with branches: a count point is set at the beginning of the body of each branch of an exception catcher For instance, compiling with jocamlcp -pfilm profiles function calls, if ... then ... else ..., loops, and pattern matching. Calling jocamlcp(1) without the -p option defaults to -p fm meaning that only function calls and pattern matching are profiled. Note: due to the implementation of streams and stream patterns as syntactic sugar, it is hard to predict what parts of stream expressions and patterns will be profiled by a given flag. To profile a program with streams, we recommend using jocamlcp -p a. SEE ALSO
