How to alias this awk?
Hi,

I am running the following df command to display df in GB. I am not able to use df -h on this server as that option is not available.

Code:
 
 df -k /tmp | awk 'NR==1 {CNV=1024*1024;GBYTES="GBytes";FMT="%-35s %-10s %-10s %-10s %10s %-s\n"; printf FMT, $1, GBYTES, $3, $4, $5, $6; next} {printf FMT,$1,$2/CNV,$3/CNV,$4/CNV,$5,$6}'

Sample output below:

Code:
 
 $: df -k /tmp | awk 'NR==1 {CNV=1024*1024;GBYTES="GBytes";FMT="%-35s %-10s %-10s %-10s %10s %-s\n"; printf FMT, $1, GBYTES, $3, $4, $5, $6; next} {printf FMT,$1,$2/CNV,$3/CNV,$4/CNV,$5,$6}'
  
 Filesystem                          GBytes     used       avail        capacity Mounted
swap                                33.2402    0.0285187  33.2117            1% /tmp

I tried to alias this as below:

Code:
alias x='df -k $1 | awk \'NR==1 {CNV=1024*1024;GBYTES="GBytes";FMT="%-35s %-10s %-10s %-10s %10s %-s\n"; printf FMT, $1, GBYTES, $3, $4, $5, $6; next} {printf FMT,$1,$2/CNV,$3/CNV,$4/CNV,$5,$6}\''

But it is 'complaining' that there is a missing single quote. After running the alias above, it presents me a > instead.

Currently, the workaround that I am doing is to create dummy script named /tmp/df_g.ksh

Code:
 
 #!/bin/ksh
 df -k $1 | awk 'NR==1 {CNV=1024*1024;GBYTES="GBytes";FMT="%-35s %-10s %-10s %-10s %10s %-s\n"; printf FMT, $1, GBYTES, $3, $4, $5, $6; next} {printf FMT,$1,$2/CNV,$3/CNV,$4/CNV,$5,$6}'
 exit 0

And then I included the following in my .profile.

Code:
 
 alias df_g='/tmp/df_g.ksh'

Now, I can run it as df_g /tmp.

Is there any way that I can alias the awk without using the dummy script?

ttk_image

ttk_image(n)							 Tk Themed Widget						      ttk_image(n)

__________________________________________________________________________________________________________________________________________________

NAME

       ttk_image - Define an element based on an image

SYNOPSIS

       ttk::style element create name image imageSpec ?options?
_________________________________________________________________

DESCRIPTION

       The  image  element  factory creates a new element in the current theme whose visual appearance is determined by Tk images.  imageSpec is a
       list of one or more elements.  The first element is the default image name.  The rest of the list is a sequence of statespec / value  pairs
       specifying other images to use when the element is in a particular state or combination of states.

OPTIONS

       Valid options are:

       -border padding
	      padding  is a list of up to four integers, specifying the left, top, right, and bottom borders, respectively.  See IMAGE STRETCHING,
	      below.

       -height height
	      Specifies a minimum height for the element.  If less than zero, the base image's height is used as a default.

       -padding padding
	      Specifies the element's interior padding.  Defaults to -border if not specified.

       -sticky spec
	      Specifies how the image is placed within the final parcel.  spec contains zero or more characters "n", "s", "w", or "e".

       -width width
	      Specifies a minimum width for the element.  If less than zero, the base image's width is used as a default.

IMAGE STRETCHING

       If the element's allocated parcel is larger than the image, the image will be placed in the parcel based on the	-sticky  option.   If  the
       image  needs to stretch horizontally (i.e., -sticky ew) or vertically (-sticky ns), subregions of the image are replicated to fill the par-
       cel based on the -border option.  The -border divides the image into 9 regions: four fixed corners, top and left edges (which may be  tiled
       horizontally), left and right edges (which may be tiled vertically), and the central area (which may be tiled in both directions).

EXAMPLE

	      set img1 [image create photo -file button.png]
	      set img2 [image create photo -file button-pressed.png]
	      set img3 [image create photo -file button-active.png]
	      style element create Button.button image 
		  [list $img1  pressed $img2  active $img3] 
		  -border {2 4} -sticky we
