I was trying to figure out how to write a shell script to be able to print the name of the file and size to a text file I wanted to know if I was on the right track and am understanding this better.
In my script a for loop be able to print files over 4mb (we charge differently for larger images)
my understanding:
check variable $image that is being set from the directory
f is all images from *
do f's size and make a variable inside $()
stat -c %s prints the file name?
if condition is met for fsize equals 4mb size
print variable $f
to file results.txt
Is there a command that will return the name of the largest file within a directory? If so, can I set the returned filename into a variable? (4 Replies)

image(n) Tk Built-In Commands image(n)
__________________________________________________________________________________________________________________________________________________NAME
image - Create and manipulate images
SYNOPSIS
image option ?arg arg ...?
_________________________________________________________________DESCRIPTION
The image command is used to create, delete, and query images. It can take several different forms, depending on the option argument. The
legal forms are:
image create type ?name? ?option value ...?
Creates a new image and returns its name. type specifies the type of the image, which must be one of the types currently defined
(e.g., bitmap). name specifies the name for the image; if it is omitted then Tk picks a name of the form imagex, where x is an
integer. There may be any number of option-value pairs, which provide configuration options for the new image. The legal set of
options is defined separately for each image type; see below for details on the options for built-in image types. If an image
already exists by the given name then it is replaced with the new image and any instances of that image will redisplay with the new
contents. It is important to note that the image command will silently overwrite any procedure that may currently be defined by the
given name, so choose the name wisely. It is recommended to use a separate namespace for image names (e.g., ::img::logo,
::img::large).
image delete ?name name ...?
Deletes each of the named images and returns an empty string. If there are instances of the images displayed in widgets, the images
won't actually be deleted until all of the instances are released. However, the association between the instances and the image
manager will be dropped. Existing instances will retain their sizes but redisplay as empty areas. If a deleted image is recreated
with another call to image create, the existing instances will use the new image.
image height name
Returns a decimal string giving the height of image name in pixels.
image names
Returns a list containing the names of all existing images.
image type name
Returns the type of image name (the value of the type argument to image create when the image was created).
image types
Returns a list whose elements are all of the valid image types (i.e., all of the values that may be supplied for the type argument
to image create).
image width name
Returns a decimal string giving the width of image name in pixels.
BUILT-IN IMAGE TYPES
The following image types are defined by Tk so they will be available in any Tk application. Individual applications or extensions may
define additional types.
bitmap Each pixel in the image displays a foreground color, a background color, or nothing. See the bitmap manual entry for more informa-
tion.
photo Displays a variety of full-color images, using dithering to approximate colors on displays with limited color capabilities. See the
photo manual entry for more information.
