ptee - duplicate standard input to several subshells, executing in parallel Duplicate standard input to standard output as well as any number of sub-commands given on the command line. Each sub-command is executed in the context of a shell. By default, the shell given in the SHELL environment variable is used. If not defined, /bin/sh is used. As each command is run in a shell, any number of shell commands can be used, such as pipes and redirects. ptee does only minimal buffering. If any sub-command stalls, the entire pipeline will stall. As such, the pipeline will only run at the speed of the slowest component. EXAMPLES ======== Emulate `tee`: ... | ptee "cat > outputfile" | ... Create two filtered, compressed files: ... | ptee "grep foo | zcat > out1.gz" "grep bar | zcat > out2.gz" | ... BUGS ==== You can't specify which shell to use for subcommands. Sub-command's stdout is lost by default. There is no stdout->stdin combinator. Return code of ptee does not depend on the return code of any sub-shell. Does not vary its physical training regime. Shells may suffer from RSI. There are no options. Yann Ramin <email@example.com> (c) 2009 Yann Ramin. All rights reserved. Available under an MIT license from <http://github.com/theatrus/ptee>
