This way you can give names to directories, that you visit often. It even looks nice in your prompt. This isn't stricly an alias, but you can think of them as aliases. text/html 2010-01-05T09:20:47+02:00 http://www.zshwiki.org/home/examples/aliasglobal?rev=1262679647 Global aliases - Do not have to be at the beginning of the command line. Typical use is: alias -g H='| head' alias -g T='| tail' alias -g G='| grep' alias -g L="| less" alias -g M="| most" alias -g B="&|" alias -g HL="--help" alias -g LL="2>&1 | less" alias -g CA="2>&1 | cat -A" alias -g NE="2> /dev/null" alias -g NUL="> /dev/null 2>&1" text/html 2010-01-05T09:20:47+02:00 http://www.zshwiki.org/home/examples/aliasnormal?rev=1262679647 Cleaning up This is useful, if you want to remove systemwide aliases from your config: # Clean up unwanted system aliases and start from scratch. unhash -am '*' Common Aliases # fast directory change alias ...='cd ../..' alias ....='cd ../../..' alias .....='cd ../../../..' alias ......='cd ../../../../..' alias .......='cd ../../../../../..' # upgrade shortcut for debian users [ -r /etc/debian_version ] && [ -x `which sudo` ] && alias upgrade='sudo apt-get update && sudo apt-get -u upg… text/html 2010-01-05T09:20:47+02:00 http://www.zshwiki.org/home/examples/aliassuffix?rev=1262679647 Since zsh 4.2.x its possible to make a programme alias for a given filename extension. That means, you can assign commands to filename suffixes. alias -s txt='less -rE' Now every time you enter a $filename with extension .txt less -rE $filename is invoked. If you use `*.txt' then all files with that extension will be invoked with the command less with options -r -E. text/html 2010-01-05T09:20:47+02:00 http://www.zshwiki.org/home/examples/compctl?rev=1262679647 The 'old' style of completion. It's got quite a lot of fans, because it is a lot quicker than the new system. Here are a few examples, on how you can configure this system: # simple completions # complete only dirs (or symlinks to dirs in some cases) for certain commands compctl -g '*(/)' rmdir dircmp compctl -g '*(-/)' cd chdir dirs pushd # hosts completion for a few commands compctl -k hosts ftp lftp ncftp ssh w3m lynx links elinks nc telnet rlogin host compctl -k hosts -P '@' finger # m… text/html 2010-01-05T09:20:47+02:00 http://www.zshwiki.org/home/examples/compquickstart?rev=1262679647 There are quite a lot of zsh users that do use the new compsys (via compinit), but do not know how much it can do. There's a compinstall function in newer versions of the shell, that does some inititalizations if the shell can't find ~/.zshrc, which is fine, but to give new users an idea of what can be done, paste this to your .zshrc: text/html 2010-01-05T09:20:47+02:00 http://www.zshwiki.org/home/examples/expnhistory?rev=1262679647 ^foo^bar To retrieve the last command replacing a certain pattern once: % mv foo.c old/ # very silly example, I know... % ^foo^bar % mv bar.c old/ However if you need to replace all occurences, with zsh 4.3.1 you can use: % mv foo.c foo_archive % ^foo^bar:G % mv bar.c bar_archive text/html 2010-01-05T09:20:47+02:00 http://www.zshwiki.org/home/examples/expnparam?rev=1262679647 Apart from this page, we do now have pageset that discusses parameter expansion in more detail.

There are a few reasons for this: * I noticed that the <elapsed seconds> of EXTENDED_HISTORY is always set to zero when INC_APPEND_HISTORY or SHARED_HISTORY is set. (I would like to have them both, and would be perfectly content with having each command line written to the history when execution finishes, rather that when it begins.) * I would like to re-write forced redir… text/html 2010-01-05T09:20:47+02:00 http://www.zshwiki.org/home/examples/zleiab?rev=1262679647 I saw this idea in strcat's config for the first time. This way you can get a similar featureset as with global aliases, but without its dangers and with additional flexiblity. The idea is, to enter unique strings that get replaced with something useful as soon as the space-key gets hit: text/html 2010-01-05T09:20:47+02:00 http://www.zshwiki.org/home/examples/zlewidgets?rev=1262679647 Just to hint you at a few widgets, that are already there...
