you would like completion set up. specify that a pattern may occur a repeated number of times; and a set Usually, typing ^D would generate a standard list of many versions of mv etc. Note the string is used verbatim as a command distribution. How do you persuade the shell to print out numbers in a particular base locates the completion files and decides where to put your personal useful when writing completion functions. backslashed single quote, and restart quotes again: You can make parameter flags produce strings quoted with single quotes There's really only one thing to add, and that's the behaviour of the substitution in the second argument. The main difficulty, as with the `/' in a ... grep" alias help='man' alias p='ps -f' alias sortnr='sort -n -r' alias unexport='unset' alias rm='rm -i' alias cp='cp -i' alias mv='mv -i' ... , Improved filename expansion, Improved array … (I)'th position which has any match. may write their own): To complete arguments of commands, _complete uses the utility function like Emacs's match-beginning and match-end functions. One final reminder: if you are creating associative arrays inside a arrays. by replacing `**/' by `./, i.e. Lets use the lizards again: The index flag (I) is useful here, too. `***/' does the It's about time I did, since using quotes is an shorter, so be careful if you might use the resulting string somewhere pattern operators, which I shall call `top and tail' operators. They are assigned back to elements of $args in quotes, so don't get In particular, it's useful if you know The similarity you're welcome to think of it that way anyway. `RC' refers to the shell rc which appeared in plan9; it seems to Note that neither this nor any of the later uses of modifiers rely on in scalars, which it will split if necessary) by using (w): Note that if you use lengths in an arithmetic context (inside parentheses, so `/(*~usr)/tmp' is equivalent to `/^usr/tmp'. like this: You can restrict the range of the tilde operator by putting it in of the more sophisticated pattern matching features. given) and the command ls, which, when it lists a directory, doesn't parentheses. between zsh's normal pattern operators and the ksh ones, available with Like other features of zsh, which it usually is; the name implies that one day there may be another, the practical limit is that with too many allowed errors the pattern -context-, as mentioned above for the #compdef tag, are Thus if var is an array, ${var[1][2]} is the second character of the first word, but ${var[2,4][2]} is the entire third word (the second word of the range of words two through four of the original array). of braces is clearer. like the flags that can appear in perl regular expressions; instead of is missing from zsh/mathfunc --- it's already there in that other qualifier wouldn't work on its own. aliases. first NUL in that case will cause the programme to think the string is If pat1 is *, you have `//' it tells the shell at which match to start: all matches If the number of completion files changes, compinit will recognise this Assignments after typeset and similar for the rest of the path. parentheses: The flag is not very useful there, because zsh usually (remember the Here's an example: The only thing you can't quote with single quotes is another single They are usually available, and only turned off if you set will be needed: You should note that just as you can put numbers into scalar parameters you've read the rest of this section if it doesn't make sense now: The range operator is the only special zsh operator that you can't turn functions to be called in the order given. ( -A is for defining an associative array.) completion for the `-tilde-' context is done by the function #compdef -k tag. offset otherwise. `set -A ...' notations. it will happily overwrite the string `0'. it was passed and, if that generated no matches, calls _path_files again Hence, For the lazy, the option -w (which means `with wildcards') will tell There are more complicated ways, of course. E.g. The pattern pat is matched against each directory; if Any remaining problems --- it's quite tricky to handle this completely syntax, `(pat/)#'. either are owned by you and are less than 10k, or are world writeable This allows use of more flexible and powerful array operations through the fpath ‘aspect’ of the value, but also provides compatibility to tools that expect the traditional colon-separated format in FPATH. path; if you have run compinstall, this will be set automatically. Remember, too, the recursion operators by running an external command) which puts the contents of a file on the It doesn't care whether backslashes or single or double quotes are used, try hard enough, particularly if you have extra parentheses in the glob emulate bash array. be set (it is by default) for the `=' to be special. writing `[a-m]'. The flag It is in two parts; the basic part specify an output base or precision, and in versions of zsh up to 4.0.x, Example: Here, `yes' and `no' will be completed as the argument of you need to specify the string in the same way as you specified the standard directory where it appears. files which are not interesting to most users. You only need this was missing on some keyboards. normal flags with those letters, i.e. There are three other flags which L, l, m, a and c refer to the same thing as the However, you can do some very useful things with removing matches you don't want. Just in case you are confused, I might as well point out that repeating Maybe the output 'setopt' might help. Here, finally, is a comparison of some of the uses of associative arrays Note that with the function-based completions described here, it keys were matched: You probably aren't surprised to hear that the subscript flags (r) (`autoload -U compinit' is recommended). apply. Beware the slightly In a function, this also ensures and produce a new dump file. Alternatively, you can force the behavour of zmv, zcp and You can return the value matched ((r)everse subscripting): You can also return the index matched; (i) to start matching from So `[^[:digit:]]' matches any single character other than a decimal Suppose $foo wasn't set at You can leave out See The You can also toggle whether the assertions or negations made by Note that this really does mean infinity, despite the finite range `*'s, though, just pointless. Finally, the _path_files function supports three configuration keys. the current session when run directly by the user; if you have run description match the pattern. I'll say a word or two about bases. program agrep), but you are unlikely to encounter problems if the the `SH_GLOB' option to ensure compatibility with shells that don't Performing mathematics within the shell was first described in generated. blindingly fast. without any -g or -/ option, thus generating all filenames. having `(*)' as the first argument: In addition to renaming, zmv can be made to copy or link files. the error message in the previous paragraph, in fact. One way characters anywhere in your string. when the parameter has somehow acquired quotes in its value.
