Threader executes a given command (-run) in x parallel threads. It can be used to just execute the Command a defined number of times (-runs) or to pass input given by STDIN split by a delimiter and provide each result part as \$INPUTSTR param to your -run command.
Threader is shipped with /bin/bash as only dependency.
$ git clone https://github.com/voodooEntity/threader
$ cd threader $ make && make build && make install If you want to use the shipped binary simply download it and execute (currently only debian64bit build)
$ sudo cp bin/deb64/threader /usr/bin/threader - -run "yourcommand"
- Can include \$INPUTSTR \$INPUTID \$THREADID
- -runs INT
- Amount of run executions to be done if no input is given
- -delimiter "delimiterstring"
- String to split stdin given input up to single command inputstr , default delimiter="\n"
- -verbose on
- Sets threaders core output to verbose mode for debugging purposes
- -threads INT
- Define a number of threads to be used for parallel execution, default threads=amount of cpus
The following vars can be used in your execution command.
- \$INPUTSTR
- This variable will include a single input part provided by the result of splitting the STDIN input by -delimiter string.
- \$INPUTID
- This variable will include a the id of the given \$INPUTSTR. This variable is only unique for each thread, not in total.
- \$THREADID
- This variable will include a the id of the thread executing the current command. It can be used to create unique identifiers combined with \$INPUTID
