``string`` performs operations on strings.

STRING arguments are taken from the command line unless standard input is connected to a pipe or a file, in which case they are read from standard input, one STRING per line. It is an error to supply STRING arguments on the command line and on standard input.

2018-12-20 04:02:45 +08:00
Arguments beginning with ``-`` are normally interpreted as switches; ``--`` causes the following arguments not to be treated as switches even if they begin with ``-``. Switches and required arguments are recognized only on the command line.

string: Quit early if --quiet is satisfied E.g. if we do `string match -q`, and we find a match, nothing about the input can change anything, so we quit early. This is mainly useful for performance, but it also allows `string` with `-q` to be used with infinite input (e.g. `yes`). Alternative to #7495.
2020-11-29 19:06:48 +08:00
Most subcommands accept a ``-q`` or ``--quiet`` switch, which suppresses the usual output but exits with the documented status. In this case these commands will quit early, without reading all of the available input.

Add string collect The `string collect` subcommand behaves quite similarly in practice to `string split0 -m 0` in that it doesn't split its output, but it also takes an optional `--trim-newline` flag to trim a single trailing newline off of the output. See issue #159.

In general, special characters are special by default, so ``a+`` matches one or more "a"s, while ``a\+`` matches an "a" and then a "+". ``(a+)`` matches one or more "a"s in a capturing group (``(?:XXXX)`` denotes a non-capturing group). For the replacement parameter of ``replace``, ``$n`` refers to the n-th group of the match. In the match parameter, ``\n`` (e.g. ``\1``) refers back to groups.

docs/string: Add paragraph on comparison with unix tools [ci skip]
2019-04-02 18:46:23 +08:00
Comparison to other tools
-------------------------
Most operations ``string`` supports can also be done by external tools. Some of these include ``grep``, ``sed`` and ``cut``.
If you are familiar with these, it is useful to know how ``string`` differs from them.
In contrast to these classics, ``string`` reads input either from stdin or as arguments. ``string`` also does not deal with files, so it requires redirections to be used with them.
docs: use monospace for inline code snippets more consistently
2020-10-27 02:19:05 +08:00
In contrast to ``grep``, ``string``'s ``match`` defaults to glob-mode, while ``replace`` defaults to literal matching. If set to regex-mode, they use PCRE regular expressions, which is comparable to ``grep``'s ``-P`` option. ``match`` defaults to printing just the match, which is like ``grep`` with ``-o`` (use ``--entire`` to enable grep-like behavior).

docs: use monospace for inline code snippets more consistently
2020-10-27 02:19:05 +08:00
Like ``sed``'s ``s/old/new/`` command, ``string replace`` still prints strings that don't match. ``sed``'s ``-n`` in combination with a ``/p`` modifier or command is like ``string replace -f``.
