  83 parset only works if it is a function. The function is defined as part
  84 of env_parallel.
  85
  86 Do the below and restart your shell.
  87
  88 bash:  Put this in $HOME/.bashrc:  . `which env_parallel.bash`
  89        E.g. by doing:  echo '. `which env_parallel.bash`' >> $HOME/.bashrc
  90        Supports: variables, aliases, functions, arrays
  91
  92 ksh:   Put this in $HOME/.kshrc:  source `which env_parallel.ksh`
  93        E.g. by doing:  echo 'source `which env_parallel.ksh`' >> $HOME/.kshrc
  94        Supports: variables, aliases, functions, arrays
  95
  96 mksh:  Put this in $HOME/.mkshrc:  source `which env_parallel.mksh`
  97        E.g. by doing:  echo 'source `which env_parallel.mksh`' >> $HOME/.mkshrc
  98        Supports: variables, aliases, functions, arrays
  99
 100 pdksh: Put this in $HOME/.profile:  source `which env_parallel.pdksh`
 101        E.g. by doing:  echo '. `which env_parallel.pdksh`' >> $HOME/.profile
 102        Supports: variables, aliases, functions, arrays
 103
 104 zsh:   Put this in $HOME/.zshrc:  . `which env_parallel.zsh`
 105        E.g. by doing:  echo '. `which env_parallel.zsh`' >> $HOME/.zshenv
 106        Supports: variables, functions, arrays
 107
 108 ash:   Put this in $HOME/.profile:  . `which env_parallel.ash`
 109        E.g. by doing:  echo '. `which env_parallel.ash`' >> $HOME/.profile
 110        Supports: variables, aliases
 111
 112 dash:  Put this in $HOME/.profile:  . `which env_parallel.dash`
 113        E.g. by doing:  echo '. `which env_parallel.dash`' >> $HOME/.profile
 114        Supports: variables, aliases
 115

 122 To install in all shells run:
 123
 124   parset --install
 125
 126 In a script you need to run this before using parset:
 127
 128 bash:  . `which env_parallel.bash`
 129 ksh:   source `which env_parallel.ksh`
 130 mksh:  source `which env_parallel.mksh`
 131 pdksh: source `which env_parallel.pdksh`
 132 zsh:   . `which env_parallel.zsh`
 133 ash:   . `which env_parallel.ash`
 134 dash:  . `which env_parallel.dash`
 135
