## Description

`gio` is a utility that makes many of the GIO features available from the commandline. In doing so, it provides commands that are similar to traditional utilities, but let you use GIO locations instead of local files: for example you can use something like `smb://server/resource/file.txt` as location.

## Commands

`help` COMMAND

  Displays a short synopsis of the available commands or provides detailed help on a specific command.

`version`

  Prints the GLib version to which `gio` belongs.

`cat` LOCATION

  Concatenates the given files and prints them to the standard output.

  The cat command works just like the traditional cat utility.

  Note: just pipe through cat if you need its formatting options like -n, -T or other.

`copy` OPTION SOURCE DESTINATION

  Copies one or more files from SOURCE to DESTINATION. If more than one source is specified, the destination must be a directory.

  The copy command is similar to the traditional cp utility.

  ### Options

  `-T`, `--no-target-directory`

    Don't copy into DESTINATION even if it is a directory.

  `-p`, `--progress`

    Show progress.

  `-i`, `--interactive`

    Prompt for confirmation before overwriting files.

  `--preserve`

    Preserve all attributes of copied files.

  `-b`, `--backup`

    Create backups of existing destination files.

  `-P`, `--no-dereference`

    Never follow symbolic links.

`info` OPTION LOCATION

  Shows information about the given locations.

  The info command is similar to the traditional ls utility.

  ### Options

  `-w`, `--query-writable`

    List writable attributes.

  `-f`, `--filesystem`

    Show information about the filesystem that the given locations reside on.

  `-a` `--attributes=ATTRIBUTES`

    The attributes to get.

    Attributes can be specified with their GIO name, e.g. standard::icon, or just by namespace, e.g. unix, or by '*', which matches all attributes. Several attributes or groups of attributes can be specified, separated by comma.

    By default, all attributes are listed.

  `-n`, `--nofollow-symlinks`

    Don't follow symbolic links.

`list` OPTION LOCATION

  Lists the contents of the given locations. If no location is given, the contents of the current directory are shown.

  The list command is similar to the traditional ls utility.

  ### Options

  `-a` `--attributes=ATTRIBUTES`

    The attributes to get.

    Attributes can be specified with their GIO name, e.g. standard::icon, or just by namespace, e.g. unix, or by '*', which matches all attributes. Several attributes or groups of attributes can be specified, separated by comma.

    By default, all attributes are listed.

  `-h`, `--hidden`

    Show hidden files.

  `-l`, `--long`

    Use a long listing format.

  `-n`, `--nofollow-symlinks`

    Don't follow symbolic links.

  `-u`, `--print-uris`

    Print full URIs.

`mime` MIMETYPE HANDLER

  If no handler is given, the mime command lists the registered and recommended applications for the mimetype. If a handler is given, it is set as the default handler for the mimetype.

  Handlers must be specified by their desktop file name, including the extension. Example: org.gnome.gedit.desktop.

`mkdir` OPTION LOCATION

  Creates directories.

  The mkdir command is similar to the traditional mkdir utility.

  ### Options

  `-p`, `--parent`

    Create parent directories when necessary.

`monitor` OPTION LOCATION

  Monitors files or directories for changes, such as creation deletion, content and attribute changes, and mount and unmount operations affecting the monitored locations.

  The monitor command uses the GIO file monitoring APIs to do its job. GIO has different implementations for different platforms. The most common implementation on Linux uses inotify.

  ### Options

  `-d`, `--dir=LOCATION`

    Monitor the given location as a directory. Normally, the file type is used to determine whether to monitor a file or directory.

  `-f`, `--file=LOCATION`

    Monitor the given location as a file. Normally, the file type is used to determine whether to monitor a file or directory.

  `-D`, `--direct=LOCATION`

    Monitor the file directly. This allows to capture changes made via hardlinks.

  `-s`, `--silent=LOCATION`

    Monitor the file directly, but don't report changes.

  `-n`, `--no-moves`

    Report moves and renames as simple deleted/created events.

  `-m`, `--mounts`

    Watch for mount events.

`mount` OPTION LOCATION

  Provides commandline access to various aspects of GIOs mounting functionality.

  Mounting refers to the traditional concept of arranging multiple file systems and devices in a single tree, rooted at /. Classical mounting happens in the kernel and is controlle by the mount utility. GIO expands this concept by introducing mount daemons that can make file systems available to GIO applications without kernel involvement.

  GIO mounts can require authentication, and the mount command may ask for user IDs, passwords, and so on, when required.

  ### Options

  `-m`, `--mountable`

    Mount as mountable.

  `-d`, `--device=DEVICE`

    Mount volume with device file.

  `-u`, `--unmount`

    Unmount the location.

  `-e`, `--eject`

    Eject the location.

  `-s`, `--unmount-scheme=SCHEME`

    Unmount all mounts with the given scheme.

  `-f`, `--force`

    Ignore outstanding file operations when unmounting or ejecting.

  `-a`, `--anonymous`

    Use an anonymous user when authenticating.

  `-l`, `--list`

    List all GIO mounts.

  `-o`, `--monitor`

    Monitor mount-related events.

  `-i`, `--detail`

    Show extra information.

`move` OPTION SOURCE DESTINATION

  Moves one or more files from SOURCE to DESTINATION. If more than one source is specified, the destination must be a directory.

  The move command is similar to the traditional mv utility.

`open` LOCATION

  Opens files with the default application that is registered to handle files of this type.

  GIO obtains this information from the shared-mime-info database, with per-user overrides stored in ``$XDG_DATA_HOME`/applications/mimeapps.list`.

  The mime command can be used to change the default handler for a mimetype.

`rename` LOCATION NAME

  Renames a file.

  The rename command is similar to the traditional rename utility.

`remove` OPTION LOCATION

  Deletes each given file.

  This command removes files irreversibly. If you want a reversible way to remove files, see the trash command.

  Note that not all URI schemes that are supported by GIO may allow deletion of files.

  The remove command is similar to the traditional rm utility.

  ### Options

  `-f`, `--force`

    Ignore non-existent and non-deletable files.

`save` OPTION DESTINATION

  Reads from standard input and saves the data to the given location.

  This is similar to just redirecting output to a file using traditional shell syntax, but the save command allows saving to location that GIO can write to.

  ### Options

  `-b`, `--backup`

    Backup existing destination files.

  `-c`, `--create`

    Only create the destination if it doesn't exist yet.

  `-a`, `--append`

    Append to the end of the file.

  `-p`, `--private`

    When creating, restrict access to the current user.

  `-u`, `--unlink`

    When replacing, replace as if the destination did not exist.

  `-v`, `--print-etag`

    Print the new etag in the end.

  `-e`, `--etag=ETAG`

    The etag of the file that is overwritten.

`set` LOCATION ATTRIBUTE VALUE

  Allows to set a file attribute on a file.

  File attributes can be specified with their GIO name, e.g standard::icon. Note that not all GIO file attributes are writable. Use the --query-writable option of the info command to list writable file attributes.

  If the TYPE is unset, VALUE does not have to be specified. If the type is stringv, multiple values can be given.

  ### Options

  `-t`, `--type=TYPE`

    Specifies the type of the attribute. Supported types are string, stringv, bytestring, boolean, uint32, int32, uint64, int64 and unset.

    If the type is not specified, string is assumed.

  `-n`, `--nofollow-symlinks`

    Don't follow symbolic links.

`trash` OPTION LOCATION

  Sends files or directories to the "Trashcan". This can be a different folder depending on where the file is located, and not all file systems support this concept. In the common case that the file lives inside a users home directory, the trash folder is ``$XDG_DATA_HOME`/Trash`.

  Note that moving files to the trash does not free up space on the file system until the "Trashcan" is emptied. If you are interested in deleting a file irreversibly, see the remove command.

  Inspecting and emptying the "Trashcan" is normally supported by graphical file managers such as nautilus, but you can also see the trash with the command: gio list trash://.

  ### Options

  `-f`, `--force`

    Ignore non-existent and non-deletable files.

  `--empty`

    Empty the trash.

`tree` OPTION LOCATION

  Lists the contents of the given locations recursively, in a tree-like format. If no location is given, it defaults to the current directory.

  The tree command is similar to the traditional tree utility.

  ### Options

  `-h`, `--hidden`

    Show hidden files.

  `-l`, `--follow-symlinks`

    Follow symbolic links.

## Exit status

On success 0 is returned, a non-zero failure code otherwise.
