parset only works if it is a function. The function is defined as part
of env_parallel.
Do the below and restart your shell.
bash: Put this in $HOME/.bashrc: . `which env_parallel.bash`
E.g. by doing: echo '. `which env_parallel.bash`' >> $HOME/.bashrc
Supports: variables, aliases, functions, arrays
ksh: Put this in $HOME/.kshrc: source `which env_parallel.ksh`
E.g. by doing: echo 'source `which env_parallel.ksh`' >> $HOME/.kshrc
Supports: variables, aliases, functions, arrays
mksh: Put this in $HOME/.mkshrc: source `which env_parallel.mksh`
E.g. by doing: echo 'source `which env_parallel.mksh`' >> $HOME/.mkshrc
Supports: variables, aliases, functions, arrays
pdksh: Put this in $HOME/.profile: source `which env_parallel.pdksh`
E.g. by doing: echo '. `which env_parallel.pdksh`' >> $HOME/.profile
Supports: variables, aliases, functions, arrays
zsh: Put this in $HOME/.zshrc: . `which env_parallel.zsh`
E.g. by doing: echo '. `which env_parallel.zsh`' >> $HOME/.zshenv
Supports: variables, functions, arrays
ash: Put this in $HOME/.profile: . `which env_parallel.ash`
E.g. by doing: echo '. `which env_parallel.ash`' >> $HOME/.profile
Supports: variables, aliases
dash: Put this in $HOME/.profile: . `which env_parallel.dash`
E.g. by doing: echo '. `which env_parallel.dash`' >> $HOME/.profile
Supports: variables, aliases
fish: Unsupported
csh: Unsupported
tcsh: Unsupported
To install in all shells run:
parset --install
In a script you need to run this before using parset:
bash: . `which env_parallel.bash`
ksh: source `which env_parallel.ksh`
mksh: source `which env_parallel.mksh`
pdksh: source `which env_parallel.pdksh`
zsh: . `which env_parallel.zsh`
ash: . `which env_parallel.ash`
dash: . `which env_parallel.dash`
For details: see man parset
