The former file is read # before ~/.zshrc, the latter is read after it. Also, consider reading the # refcard and the reference manual for this setup, both available from: # # Contributing: # If you want to help to improve grml's zsh setup, clone the grml-etc-core # repository from git.grml.org: # git clone git://git.grml.org/grml-etc-core.git # # Make your changes, commit them; use 'git format-patch' to create a series # of patches and send those to the following address via 'git send-email': # grml-etc-core@grml.org # # Doing so makes sure the right people get your patches for review and # possibly inclusion. # zsh-refcard-tag documentation: # You may notice strange looking comments in this file. # These are there for a purpose. grml's zsh-refcard can now be # automatically generated from the contents of the actual configuration # file. However, we need a little extra information on which comments # and what lines of code to take into account (and for what purpose). # # Here is what they mean: # # List of tags (comment types) used: # #a# Next line contains an important alias, that should # be included in the grml-zsh-refcard. # (placement tag: @@INSERT-aliases@@) # #f# Next line contains the beginning of an important function. # (placement tag: @@INSERT-functions@@) # #v# Next line contains an important variable. # (placement tag: @@INSERT-variables@@) # #k# Next line contains an important keybinding. # (placement tag: @@INSERT-keybindings@@) # #d# Hashed directories list generation: # start denotes the start of a list of 'hash -d' # definitions. # end denotes its end. # (placement tag: @@INSERT-hasheddirs@@) # #A# Abbreviation expansion list generation: # start denotes the beginning of abbreviations. # end denotes their end. # Lines within this section that end in '#d .*' provide # extra documentation to be included in the refcard. # (placement tag: @@INSERT-abbrev@@) # #m# This tag allows you to manually generate refcard entries # for code lines that are hard/impossible to parse. # Example: # #m# k ESC-h Call the run-help function # That would add a refcard entry in the keybindings table # for 'ESC-h' with the given comment. # So the syntax is: #m#
# #o# This tag lets you insert entries to the 'other' hash. # Generally, this should not be used. It is there for # things that cannot be done easily in another way. # (placement tag: @@INSERT-other-foobar@@) # # All of these tags (except for m and o) take two arguments, the first # within the tag, the other after the tag: # # #
# # # Where
is really just a number, which are defined by the # @secmap array on top of 'genrefcard.pl'. The reason for numbers # instead of names is, that for the reader, the tag should not differ # much from a regular comment. For zsh, it is a regular comment indeed. # The numbers have got the following meanings: # 0 -> "default" # 1 -> "system" # 2 -> "user" # 3 -> "debian" # 4 -> "search" # 5 -> "shortcuts" # 6 -> "services" # # So, the following will add an entry to the 'functions' table in the # 'system' section, with a (hopefully) descriptive comment: # #f1# Edit an alias via zle # edalias() { # # It will then show up in the @@INSERT-aliases-system@@ replacement tag # that can be found in 'grml-zsh-refcard.tex.in'. # If the section number is omitted, the 'default' section is assumed. # Furthermore, in 'grml-zsh-refcard.tex.in' @@INSERT-aliases@@ is # exactly the same as @@INSERT-aliases-default@@. If you want a list of # *all* aliases, for example, use @@INSERT-aliases-all@@. # zsh profiling # just execute 'ZSH_PROFILE_RC=1 zsh' and run 'zprof' to get the details if [[ $ZSH_PROFILE_RC -gt 0 ]] ; then zmodload zsh/zprof fi # load .zshrc.pre to give the user the chance to overwrite the defaults [[ -r ${ZDOTDIR:-${HOME}}/.zshrc.pre ]] && source ${ZDOTDIR:-${HOME}}/.zshrc.pre # check for version/system # check for versions (compatibility reasons) is4(){ [[ $ZSH_VERSION == <4->* ]] && return 0 return 1 } is41(){ [[ $ZSH_VERSION == 4.<1->* || $ZSH_VERSION == <5->* ]] && return 0 return 1 } is42(){ [[ $ZSH_VERSION == 4.<2->* || $ZSH_VERSION == <5->* ]] && return 0 return 1 } is425(){ [[ $ZSH_VERSION == 4.2.<5->* || $ZSH_VERSION == 4.<3->* || $ZSH_VERSION == <5->* ]] && return 0 return 1 } is43(){ [[ $ZSH_VERSION == 4.<3->* || $ZSH_VERSION == <5->* ]] && return 0 return 1 } is433(){ [[ $ZSH_VERSION == 4.3.<3->* || $ZSH_VERSION == 4.<4->* \ || $ZSH_VERSION == <5->* ]] && return 0 return 1 } is437(){ [[ $ZSH_VERSION == 4.3.<7->* || $ZSH_VERSION == 4.<4->* \ || $ZSH_VERSION == <5->* ]] && return 0 return 1 } is439(){ [[ $ZSH_VERSION == 4.3.<9->* || $ZSH_VERSION == 4.<4->* \ || $ZSH_VERSION == <5->* ]] && return 0 return 1 } #f1# Checks whether or not you're running grml isgrml(){ [[ -f /etc/grml_version ]] && return 0 return 1 } #f1# Checks whether or not you're running a grml cd isgrmlcd(){ [[ -f /etc/grml_cd ]] && return 0 return 1 } if isgrml ; then #f1# Checks whether or not you're running grml-small isgrmlsmall() { if [[ ${${${(f)"$( autologin # Thanks go to Bart Schaefer! isgrml && checkhome() { if [[ -z "$ALREADY_DID_CD_HOME" ]] ; then export ALREADY_DID_CD_HOME=$HOME cd fi } # check for zsh v3.1.7+ if !

It is a rather simple one-line prompt, that by default looks something like this: @ [ ]% The prompt itself integrates with zsh's prompt themes system (as you are witnessing right now) and is configurable to a certain degree. In particular, these aspects are customisable: - The items used in the prompt (e.g. you can remove \`user' from the list of activated items, which will cause the user name to be omitted from the prompt string). - The attributes used with the items are customisable via strings used before and after the actual item. The available items are: at, battery, change-root, date, grml-chroot, history, host, jobs, newline, path, percent, rc, rc-always, sad-smiley, shell-level, time, user, vcs The actual configuration is done via zsh's \`zstyle' mechanism. The context, that is used while looking up styles is: ':prompt:grml::' Here is either \`left' or \`right', signifying whether the style should affect the left or the right prompt. is either \`setup' or 'items:', where \`' is one of the available items. The styles: - use-rprompt (boolean): If \`true' (the default), print a sad smiley in $RPROMPT if the last command a returned non-successful error code. (This in only valid if is "right"; ignored otherwise) - items (list): The list of items used in the prompt. If \`vcs' is present in the list, the theme's code invokes \`vcs_info' accordingly. Default (left): rc change-root user at host path vcs percent; Default (right): sad-smiley Available styles in 'items:' are: pre, post. These are strings that are inserted before (pre) and after (post) the item in question. Thus, the following would cause the user name to be printed in red instead of the default blue: zstyle ':prompt:grml:*:items:user' pre '%F{red}' Note, that the \`post' style may remain at its default value, because its default value is '%f', which turns the foreground text attribute off (which is exactly, what is still required with the new \`pre' value). __EOF0__ } function prompt_grml-chroot_help () { <<__EOF0__ prompt grml-chroot This is a variation of the grml prompt, see: prompt -h grml The main difference is the default value of the \`items' style.

     is the name for the newly added token. If the \`-f' or \`-i' options
    are used,  is the name of the function (see below for
    details). Otherwise it is the literal token string to be used. 
 and
     are optional.

  Options:

    -f    Use a function named \`' each time the token
                    is to be expanded.

    -i    Use a function named \`' to initialise the
                    value of the token _once_ at runtime.

    The functions are called with one argument: the token's new name. The
    return value is expected in the \$REPLY parameter. The use of these
    options is mutually exclusive.

    There is a utility function \`grml_theme_has_token', which you can use
    to test if a token exists before trying to add it. This can be a guard
    for situations in which a \`grml_theme_add_token' call may happen more
    than once.

  Example:

    To add a new token \`day' that expands to the current weekday in the
    current locale in green foreground colour, use this:

      grml_theme_add_token day '%D{%A}' '%F{green}' '%f'

    Another example would be support for \$VIRTUAL_ENV:

      function virtual_env_prompt () {
        REPLY=\${VIRTUAL_ENV+\${VIRTUAL_ENV:t} }
      }
      grml_theme_add_token virtual-env -f virtual_env_prompt

    After that, you will be able to use a changed \`items' style to
    assemble your prompt.

zsh-help - hints for use of zsh on grml
=======================================$reset_color"

    print '
Main configuration of zsh happens in /etc/zsh/zshrc.
That file is part of the package grml-etc-core, if you want to
use them on a non-grml-system just get the tar.gz from
http://deb.grml.org/ or (preferably) get it from the git repository:

  http://git.grml.org/f/grml-etc-core/etc/zsh/zshrc

This version of grml'\''s zsh setup does not use skel/.zshrc anymore.
The file is still there, but it is empty for backwards compatibility.

For your own changes use these two files:
    $HOME/.zshrc.pre
    $HOME/.zshrc.local

The former is sourced very early in our zshrc, the latter is sourced
very lately.

System wide configuration without touching configuration files of grml
can take place in /etc/zsh/zshrc.local.

For information regarding zsh start at http://grml.org/zsh/

Take a look at grml'\''s zsh refcard:
% xpdf =(zcat /usr/share/doc/grml-docs/zsh/grml-zsh-refcard.pdf.gz)

Check out the main zsh refcard:
% '$BROWSER' http://www.bash2zsh.com/zsh_refcard/refcard.pdf

And of course visit the zsh-lovers:
% man zsh-lovers

You can adjust some options through environment variables when
invoking zsh without having to edit configuration files.
Basically meant for bash users who are not used to the power of
the zsh yet. :)

  "NOCOR=1    zsh" => deactivate automatic correction
  "NOMENU=1   zsh" => do not use auto menu completion
                      (note: use ctrl-d for completion instead!)
  "NOPRECMD=1 zsh" => disable the precmd + preexec commands (set GNU screen title)
  "NOTITLE=1  zsh" => disable setting the title of xterms without disabling
                      preexec() and precmd() completely
  "GRML_DISPLAY_BATTERY=1  zsh"
                   => activate battery status on right side of prompt (WIP)
  "COMMAND_NOT_FOUND=1 zsh"
                   => Enable a handler if an external command was not found
                      The command called in the handler can be altered by setting
                      the GRML_ZSH_CNF_HANDLER variable, the default is:
                      "/usr/share/command-not-found/command-not-found"

A value greater than 0 is enables a feature; a value equal to zero
disables it. If you like one or the other of these settings, you can
add them to ~/.zshrc.pre to ensure they are set when sourcing grml'\''s
zshrc.'

Please report wishes + bugs to the grml-team: http://grml.org/bugs/

Backup a file or folder in place and append the timestamp
Remove backups of a file or folder, or all backups in the current directory

Usage:
-h    Display this help text
-c    Keep the file/folder as is, create a copy backup using cp(1) (default)
-m    Move the file/folder, using mv(1)
-r    Remove backups of the specified file or directory, using rm(1). If none
      is provided, remove all backups in the current directory.
-a    Remove all (even hidden) backups.
-v    Verbose

The -c, -r and -m options are mutually exclusive. If specified at the same time,
the last one is used.

The return code is the sum of all cp/mv/rm return codes.
