Process Tee for less enabled shells
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.
Emulate tee:
... | ptee "cat > outputfile" | ...Create two filtered, compressed files:
... | ptee "grep foo | zcat > out1.gz" "grep bar | zcat > out2.gz" | ...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.
