This works in /bin/sh here, but not under zsh (I've tried
zsh-3.0.{0,5,6}), and I've always thought that it was a feature of zsh
that it didn't.
Example...
alpha2----~/tmp% { exec >foo
cursh> echo bar
cursh> }
zsh: command name expected
bar
alpha2----~/tmp% ls -l foo
-rw-r--r-- 1 oma1000 colloids 0 Aug 25 17:46 foo
So I guess that there is something odd with my setup. Does anybody
have any ideas? Just to start you off, these are the options that I am
setting...
alpha2----~/tmp% grep setop ~/.zshrc
compctl -o setopt unsetopt isset
#unsetopt AUTO_LIST
unsetopt BEEP # Don't beep ever.
setopt AUTO_LIST # Auto list ambiguous choices.
#setopt AUTO_MENU # Use menu completion for 2nd request.
unsetopt MENU_COMPLETE # Don't use menu completion for 1st request.
setopt ALWAYS_LAST_PROMPT # List completions after the prompt.
setopt AUTO_NAME_DIRS # ~dirname instead of absolute names.
setopt EXTENDED_GLOB # Extended filename globbing.
setopt NO_CLOBBER # Don't clobber files with >, or create with >>.
setopt LIST_TYPES # Completions get a trailing id symbol.
setopt INTERACTIVE_COMMENTS # Allow comments in interactive shells.
unsetopt NOTIFY # Wait before reporting status of background jobs.
unsetopt BG_NICE # Don't run background jobs at a lower priority.
setopt IGNORE_EOF # Don't exit on EOF.
setopt MULTIOS # Glob after redirection operator.
setopt AUTO_PUSHD
setopt PUSHD_IGNORE_DUPS
setopt PUSHD_SILENT PUSHD_TO_HOME PUSHD_MINUS
setopt HIST_IGNORE_DUPS APPEND_HISTORY
