Simple Tip of the Day

Simple Tip of the Day

[zzapper]

Hi,

It can be very useful to set a "marker" variable when you are copying/comparing files in complicated
and different paths

eg in directory

>cd /xx/yy/ggg/ccc/
type
>S=`pwd`

Then from anywhere else you can type

>cp $S/somefile<TAB> .

Where the <TAB> indicates that all of zsh's completions work


A useful alias to automate this

alias SRC='S=`pwd`;echo "S=$S"'

You could use $PWD instead of `pwd`.

Use zsh's autopushd option and refer to "S" as ~1 (or ~n). That's much
simpler.

I type ~- and then press tab to get a list of all the dirs i've been
in, and ~+ is the shortest alias for $PWD that i found.

kool

activate autopushd

% zsh -f
% setopt autopushd
% autoload -U compinit
% compinit
% cd /
% cd /tmp
% cd ~-<tab>
0 -- /home/mikaelh
1 -- /

cd ~-<TAB> then type number of directory to cd to it!!!

Superkool,

but when I put this in my .zshenv it asks

ignore insecure directories and files and continue [ny]? 
compinit: initialization aborted

how do I get it to default to y and what does insecure in this context mean?

You can't, but you don't really want to.  An answer of "n" means abort,
and an answer of "y" means to skip reading the insecure directories.

The compsys manual section says under "Initialization":

    For security reasons compinit also checks if the completion system
    would use files not owned by root or by the current user, or files
    in directories that are world- or group-writable or that are not
    owned by root or by the current user. If such files or directories
    are found, compinit will ask if the completion system should really
    be used.  To avoid these tests and make all files found be used
    without asking, use the option -u, and to make compinit silently
    ignore all insecure files and directories use the option -i. This
    security check is skipped entirely when the -C option is given.

In other words, it's paranoid about sourcing files that might have been
created or edited by a malicious third party.

It means some files somewhere have the wrong permissions, ie someone
other than you and root could write to them and run arbitrary code.
Check in $PREFIX/share/zsh/* and your .z* files, they should be 644 or
so. Maybe if you run with zsh -x it will print which file it is, not
sure.
