| ## Constructing a command line | ||||
| 
 | ||||
| hledger has an extensive and powerful command line interface. We | ||||
| strive to keep it simple and ergonomic, but you may run into one of | ||||
| the confusing real world details described in OPTIONS, below.  | ||||
| If that happens, here are some tips that may help: | ||||
| 
 | ||||
| - command-specific options must go after the command (it's fine to put all options there) (`hledger CMD OPTS ARGS`) | ||||
| - running add-on executables directly simplifies command line parsing (`hledger-ui OPTS ARGS`) | ||||
| - enclose "problematic" args in single quotes | ||||
| - if needed, also add a backslash to hide regular expression metacharacters from the shell | ||||
| - to see how a misbehaving command is being parsed, add `--debug=2`. | ||||

| ## Command line tips | ||||
| 
 | ||||
| If in doubt, keep things simple: | ||||
| 
 | ||||
| - write options after the command (`hledger CMD -OPTIONS ARGS`) | ||||
| - run add-on executables directly (`hledger-ui -OPTIONS ARGS`) | ||||
| - enclose problematic args in single quotes | ||||
| - if needed, also add a backslash to escape regexp metacharacters | ||||
| 
 | ||||
| To find out exactly how a command line is being parsed, add `--debug=2` to troubleshoot. | ||||
| 
 | ||||
| ## Unicode characters | ||||

| If you need those, either use the [include directive](journal.html#including-other-files), | ||||
| or concatenate the files, eg: `cat a.journal b.journal | hledger -f- CMD`. | ||||
| 
 | ||||
| ## Output destination | ||||
| 
 | ||||
| Some commands (print, register, stats, the balance commands)  | ||||
| can write their output to a destination other than the console.  | ||||
| This is controlled by the `-o/--output-file` option. | ||||
| 
 | ||||
| ```shell | ||||
| $ hledger balance -o -     # write to stdout (the default) | ||||
| $ hledger balance -o FILE  # write to FILE | ||||
| ``` | ||||
| 
 | ||||
| ## Output format | ||||
| 
 | ||||
| Some commands can write their output in other formats. | ||||
| Eg print and register can output CSV, and the balance commands can output CSV or HTML. | ||||
| This is controlled by the `-O/--output-format` option, or by specifying a `.csv` or `.html` file extension with `-o/--output-file`. | ||||
| 
 | ||||
| ```shell | ||||
| $ hledger balance -O csv       # write CSV to stdout | ||||
| $ hledger balance -o FILE.csv  # write CSV to FILE.csv | ||||
| ``` | ||||
| 
 | ||||
| ## Regular expressions | ||||
| 
 | ||||
| hledger uses [regular expressions](http://www.regular-expressions.info) in a number of places: | ||||
| 
 | ||||
| - [query terms](#queries), on the command line and in the hledger-web search form: `REGEX`, `desc:REGEX`, `cur:REGEX`, `tag:...=REGEX` | ||||
| - [CSV rules](#csv-rules) conditional blocks: `if REGEX ...` | ||||
| - [account alias](#rewriting-accounts) directives and options: `alias /REGEX/ = REPLACEMENT`, `--alias /REGEX/=REPLACEMENT` | ||||
| 
 | ||||
| hledger's regular expressions come from the | ||||
| [regex-tdfa](http://hackage.haskell.org/package/regex-tdfa/docs/Text-Regex-TDFA.html) | ||||
| library. In general they: | ||||
| 
 | ||||
| - are case insensitive | ||||
| - are infix matching (do not need to match the entire thing being matched) | ||||
| - are [POSIX extended regular expressions](http://www.regular-expressions.info/posix.html#ere) | ||||
| - also support [GNU word boundaries](http://www.regular-expressions.info/wordboundaries.html) (\\<, \\>, \\b, \\B) | ||||
| - and parenthesised [capturing groups](http://www.regular-expressions.info/refcapture.html) and numeric backreferences in replacement strings | ||||
| - do not support [mode modifiers](http://www.regular-expressions.info/modifiers.html) like (?s) | ||||
| 
 | ||||
| Some things to note: | ||||
| 
 | ||||
| - In the `alias` directive and `--alias` option, regular expressions | ||||
| must be enclosed in forward slashes (`/REGEX/`). Elsewhere in hledger, | ||||
| these are not required. | ||||
| 
 | ||||
| - In queries, to match a regular expression metacharacter like `$`  | ||||
| as a literal character, prepend a backslash. Eg to search for amounts with the | ||||
| dollar sign in hledger-web, write `cur:\$`. | ||||
| 
 | ||||
| - On the command line, some metacharacters like `$` have a special | ||||
| meaning to the shell and so must be escaped at least once more. | ||||
| See [Special characters](#special-characters).  | ||||
| 
 | ||||
| ## Smart dates | ||||
| 
 | ||||
| hledger's user interfaces accept a flexible "smart date" syntax (unlike dates in the journal file).  | ||||
