@node Invoking
@chapter Invoking
@command{scrotty} recognises four options:
@table @option
@item -h
@itemx --help
Print usage information and exit.
@item -v
@itemx --version
Print program name and version and exit.
@item -c
@itemx --copyright
Print copyright information and exit.
@item -d
@itemx --device NO
Select a framebuffer device, by index, to
screenshot. All framebuffers are screenshoot
if this option is omitted.
@item -e
@itemx --exec CMD
Run a command for each saved image.
Can only be specified once.
@end table
Each option can only ube used once.
In addition to these options, a filename
pattern, that does not start with a dash,
can be added. This filename pattern selects
with what filename the image should be saved.
Both the @option{--exec} and filename pattern
parameters can take format specifiers that are
expanded by @command{scrotty} when encountered.
There are two types of format specifier.
Characters preceded by a `%' are interpreted
by @code{strftime}. See @ref{strftime} or the
manual for your implemenation of @command{strftime}
for examples. These options may be used to refer
to the current date and time. The second kind are
internal to scrotty and are prefixed by `$' or
`\'. The following specifiers are recognised:
@table @asis
@item `@code{$i}'
Framebuffer index.
@item `@code{$f}'
Image filename/pathname.
Ignored in the filename pattern.
@item `@code{$n}'
Image filename.
Ignored in the filename pattern.
@item `@code{$p}'
Image width multiplied by image height.
@item `@code{$w}'
Image width.
@item `@code{$h}'
Image height.
@item `@code{$$}'
Expands to a literal `$'.
@item `@code{\n}'
Expands to new line.
@item `@code{\\}'
Expands to a literal `\'.
@item `@code{\ }'
Expands to a literal ` '.
@end table
A space that is not prefixed by a backslash in
@option{--exec} is interpreted as an argument
delimiter. This is the case even at the beginning
and end of the string and if a space was the
previous character in the string.
For example,
@command{scrotty `%Y-%m-%d_$wx$h.$i.png` --exec 'cp $f ~/.backups/shots/'}
create a file called something like @file{2014-10-28_1792x1344.0.png}
for your first framebuffer and @file{2014-10-28_1792x1344.1.png} for
your second framebuffer, and copies the saved images to @file{~/.backups/shots/}.
