alias in .zprofile - strange effect

alias in .zprofile - strange effect

[Helmut Jarausch]

Hi,

I'm using zsh GIT- 2010/07/20

In my home directory I have a .zprofile file with the following lines
export PGPPATH=~/.pgp
alias lpps="lpr -Ppsloc"
alias cdc="cd ..;cd ~-"
#if [[ $DISPLAY == ':0.0' ]]; then 
#  /usr/X11R6/bin/xmodmap ~/.Xmodmap
#fi
# export OPERADIR=/usr/local/share/opera
export NEDIT_HOME=/home/jarausch/.nedit

If I enter  'cdc', ZSH doesn't know it.

But if I (re-)define it by
alias cdc="cd ..;cd ~-"

then 'cdc' is known afterwards.
And I've debugged it, .zprofile has been run during startup.

What's going on?

Many thanks for a hint,
Helmut.

Do you have some particular reason to use a .zprofile instead of a .zshrc ?
What is the output of " zsh --verbose |& grep alias " (without quotes) ?

Best regards,

The .zprofile is sourced only by login shells. This is good for
environment variables (though I usually use .zshenv for that),
which are inherited by subprocesses, but not for aliases, which
are local to each shell instance. So, aliases need to be defined
by each shell instance. The .zshrc (sourced by interactive shells)
is generally what one wants for aliases. Of course they won't be
available in scripts.

I use a .zalias file, which I source from .zshrc:

  [[ -r ~/.zalias ]] && source ~/.zalias

and from scripts for which I want my usual aliases.
